Chinese Hackers CISA Cyber Security Ghost MFA Sensitive data

Chinese Ghost Hackers Focus on Profits, Attack Key Sectors in the US and UK


 

In the world of cybercrime, criminals usually fall into two groups. Some target individuals, tricking them for money. Others go after important organizations like hospitals and companies, hoping for bigger payouts. Although attacks on healthcare are less common, they cause major harm when they happen. Incidents like the New York Blood Center hack, where hackers stole a million patient records, show how serious the risk is. Now, a new report warns about Chinese cybercriminals, known as Ghost, who are attacking government offices, power companies, banks, factories, and hospitals. Most of their attacks have affected North America and the United Kingdom.


Ghost Hackers Active in Over 70 Countries

According to research shared by Rebecca Harpur from Blackfog, the Ghost hacking group is based in China and acts on its own without links to the government. Their main goal is to make money, not to steal secrets. Over time, this group has changed its identity multiple times, previously using names like Cring, Crypt3r, Hello, and Phantom. By rebranding, they make it harder for law enforcement agencies to track them as one single group.

Despite their tricks, agencies like the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) have raised alarms about the damage Ghost can cause. The Blackfog report explains that victims usually receive a message demanding money, threatening to either destroy stolen information or release it publicly if they refuse to pay.


How Ghost Carries Out Its Attacks

The way Ghost hackers break into systems usually follows the same pattern:

• They first find and exploit weaknesses in systems that are open to the internet, such as VPN devices, websites, and email servers.

• After getting inside, they install secret programs like Cobalt Strike and web shells to stay hidden. They often create fake accounts and disable security software once they have high-level access.

• With these privileges, they move across the network quietly and transfer sensitive data to their own servers.

• Once enough data is stolen, they release ransomware programs (often named Ghost.exe or Cring.exe) across the network. This encrypts files, destroys backup copies, and leaves a ransom note demanding payment.


Tips to Stay Protected

Although the FBI has provided detailed steps to defend against these attacks, Blackfog suggests a few important actions:

1. Keep backups of all important data and store them separately from your main network.

2. Always install the latest updates for your operating systems, applications, and firmware.

3. Use multi-factor authentication to add an extra layer of security to user accounts.

4. Divide your network into smaller parts to make it harder for hackers to move around freely if they break in.


The Ghost hacking group is not interested in spying — their focus is on making money. Organizations need to stay alert, strengthen their defenses, and act fast to prevent serious damage from these ongoing threats.

Cybercriminals Intensify Attacks on Password Managers

 

Cybercriminals are increasingly setting their sights on password managers as a way to infiltrate critical digital accounts.

According to Picus Security’s Red Report 2025, which analyzed over a million malware samples from the past year, a quarter (25%) of all malware now targets credentials stored in password managers. Researchers noted that this marks a threefold surge compared to the previous year.

“For the first time ever, stealing credentials from password stores is in the top 10 techniques listed in the MITRE ATT&CK Framework,” they said. “The report reveals that these top 10 techniques accounted for 9Beyond the growing frequency of attacks, hackers are also deploying more advanced techniques. 3% of all malicious actions in 2024.”

Advanced Hacking Techniques

Dr. Suleyman Ozarslan, co-founder and VP of Picus Labs, revealed that cybercriminals use sophisticated methods like memory scraping, registry harvesting, and breaching both local and cloud-based password stores to extract credentials.

To counter this rising threat, Ozarslan emphasized the importance of using password managers alongside multi-factor authentication (MFA). He also warned against password reuse, particularly for password.

Beyond the growing frequency of attacks, hackers are also deploying more advanced techniques. Picus Security highlighted that modern cybercriminals are now favoring long-term, multi-stage attacks that leverage a new generation of malware. These advanced infostealers are designed for stealth, persistence, and automation.

Researchers compared this evolution in cyber threats to “the perfect heist,” noting that most malware samples execute over a dozen malicious actions to bypass security defenses, escalate privileges, and exfiltrate data.

A password manager is a cybersecurity tool that securely stores, generates, and auto-fills strong passwords across websites and apps. By eliminating the need to remember multiple passwords, it strengthens security and reduces the risk of breaches. Experts consider it an essential component of cybersecurity best practices.

ADFS Cyber Security Lateral Phishing MFA Microsoft

Sophisticated Phishing Campaign Circumvents Microsoft's Multi Factor Authentication

 

A help desk phishing campaign uses spiofed login pages to target Microsoft Active Directory Federation Services (ADFS) within an organisation in order to obtain credentials and get around multi-factor authentication (MFA) protections. The campaign's main targets, as reported by Abnormal Security, are government, healthcare, and educational institutions; at least 150 targets were chosen in the attack. 

These assaults aim to infiltrate corporate email accounts to disseminate messages to additional victims within the organisation or launch financially driven attacks such as business email compromise (BEC), wherein payments are redirected to the perpetrators' accounts. 

Microsoft Active Directory Federation Services (ADFS) is an authentication system that enables users to log in once and then access various apps and services without having to enter their credentials again. It is often employed in large companies to enable single sign-on (SSO) for internal and cloud-based services. 

The perpetrators send emails to targets impersonating their company's IT team, requesting that they log in to update security settings or adopt new policies. When victims click on the embedded button, they are redirected to a phishing site that looks identical to their organization's actual ADFS login page. The phishing page prompts the victim to input their username, password, and MFA code or tricked them into approving the push notification. 

"The phishing templates also include forms designed to capture the specific second factor required to authenticate the targets account, based on the organizations configured MFA settings," reads Abnormal Security's report. "Abnormal observed templates targeting multiple commonly used MFA mechanisms, including Microsoft Authenticator, Duo Security, and SMS verification.” 

Once the victim has entered all of their information, they are sent to the real sign-in page, which reduces suspicion and gives the impression that the procedure was completed successfully. Meanwhile, the hackers use the stolen details to gain access into the victim's account, steal any valuable data, set up new email filter rules, and attempt lateral phishing.

According to Abnormal, the attackers in this campaign utilised Private Internet Access VPN to hide their location and assign an IP address that was closer to the organisation. Abnormal recommends that organisations move to modern and more secure solutions, such as Microsoft Entra, as well as add additional email filters and suspicious behaviour detection methods, to prevent phishing attempts.

The Evolving Role of Multi-Factor Authentication in Cybersecurity

 


In recent years, the cybersecurity landscape has faced an unprecedented wave of threats. State-sponsored cybercriminals and less experienced attackers armed with sophisticated tools from the dark web are relentlessly targeting weak links in global cybersecurity systems. End users, often the most vulnerable element in the security chain, are frequently exploited. As cyber threats grow increasingly sophisticated, multi-factor authentication (MFA) has emerged as a critical tool to address the limitations of password-based security systems.

The Importance of MFA in Modern Cybersecurity

Passwords, while convenient, have proven insufficient to protect against unauthorized access. MFA significantly enhances account security by adding an extra layer of protection, preventing account compromise even when login credentials are stolen. According to a Microsoft study, MFA can block 99.9% of account compromise attacks. By requiring multiple forms of verification—such as passwords, biometrics, or device-based authentication—MFA creates significant barriers for hackers, making unauthorized access extremely difficult.

Regulations and industry standards are also driving the adoption of MFA. Organizations are increasingly required to implement MFA to safeguard sensitive data and comply with security protocols. As a cornerstone of modern cybersecurity strategies, MFA has proven effective in protecting against breaches, ensuring the integrity of digital ecosystems, and fostering trust in organizational security frameworks.

However, as cyber threats evolve, traditional MFA systems are becoming increasingly inadequate. Many legacy MFA systems rely on outdated technology, making them vulnerable to phishing attacks, ransomware campaigns, and sophisticated exploits. The advent of generative AI tools has further exacerbated the situation, enabling attackers to create highly convincing phishing campaigns, automate complex exploits, and identify security gaps in real-time.

Users are also growing frustrated with cumbersome and inconsistent authentication processes, which undermine adherence to security protocols and erode organizational defenses. This situation underscores the urgent need for a reevaluation of security strategies and the adoption of more robust, adaptive measures.

The Role of AI in Phishing and MFA Vulnerabilities

Artificial intelligence (AI) has become a double-edged sword in cybersecurity. While it offers powerful tools for enhancing security, it also poses significant threats when misused by cybercriminals. AI-driven phishing attacks, for instance, are now virtually indistinguishable from legitimate communications. Traditional phishing indicators—such as typographical errors, excessive urgency, and implausible offers—are often absent in these attacks.

AI enables attackers to craft emails and messages that appear authentic, cleverly designed to deceive even well-trained users. Beyond mere imitation, AI systems can analyze corporate communication patterns and replicate them with remarkable accuracy. Chatbots powered by AI can interact with users in real-time, while deepfake technologies allow cybercriminals to impersonate trusted individuals with unprecedented ease. These advancements have transformed phishing from a crude practice into a precise, calculated science.

Outdated MFA systems are particularly vulnerable to these AI-driven attacks, exposing organizations to large-scale, highly successful campaigns. As generative AI continues to evolve at an exponential rate, the potential for misuse highlights the urgent need for robust, adaptive security measures.

Comprehensive Multi-Factor Authentication: A Closer Look

Multi-Factor Authentication (MFA) remains a cornerstone of cybersecurity, utilizing multiple verification steps to ensure that only authorized users gain access to systems or data. By incorporating layers of authentication, MFA significantly enhances security against evolving cyber threats. The process typically begins with the user providing credentials, such as a username and password. Once verified, an additional layer of authentication—such as a one-time password (OTP), biometric input, or other pre-set methods—is required. Access is only granted after all factors are successfully confirmed.

Key forms of MFA authentication include:

  1. Knowledge-Based Authentication: This involves information known only to the user, such as passwords or PINs. While widely used, these methods are vulnerable to phishing and social engineering attacks.
  2. Possession-Based Authentication: This requires the user to possess a physical item, such as a smartphone with an authentication app, a smart card, or a security token. These devices often generate temporary codes that must be used in combination with a password.
  3. Biometric Authentication: This verifies a user's identity through unique physical traits, such as fingerprints or facial recognition, adding an extra layer of security and personalization.
  4. Location-Based Authentication: This uses GPS data or IP addresses to determine the user's geographical location, restricting access to trusted or authorized areas.
  5. Behavioral Biometrics: This tracks and monitors unique user behaviors, such as typing speed, voice characteristics, or walking patterns, providing an adaptive layer of security.

The combination of these diverse approaches creates a robust defense against unauthorized access, ensuring superior protection against increasingly sophisticated cyberattacks. As organizations strive to safeguard sensitive data and maintain security, the integration of comprehensive MFA solutions is essential.

The cybersecurity landscape is evolving rapidly, with AI-driven threats posing new challenges to traditional security measures like MFA. While MFA remains a critical tool for enhancing security, its effectiveness depends on the adoption of modern, adaptive solutions that can counter sophisticated attacks. By integrating advanced MFA methods and staying vigilant against emerging threats, organizations can better protect their systems and data in an increasingly complex digital environment.

Cyber Crime Lazarus hacking group MFA North Korea

North Korean Hackers Exploit RID Hijacking to Gain Full Control Over Windows Systems

 


A North Korean cybercriminal group, Andariel, has been found using a stealthy hacking technique called RID hijacking to gain full control over Windows systems. This method allows attackers to manipulate a computer’s security settings, turning a low-privilege user account into an administrator account and granting them hidden control over the system.

What is RID Hijacking and How Does It Work?

Windows assigns each user account a Security Identifier (SID), which includes a Relative Identifier (RID) that defines the account’s access level. Key RIDs include:

  • 500 – Default administrator account
  • 501 – Guest account
  • 1000+ – Regular user accounts

Hackers exploit this system by modifying the RID of a normal user account to match that of an administrator. Since Windows determines permissions based on RID values, the system unknowingly grants higher-level access to what appears to be a low-privilege account. However, this attack requires deep access to the system’s core security files, specifically the Security Account Manager (SAM) registry, where user login details are stored.

Researchers from AhnLab Security Intelligence Center (ASEC) have linked these attacks to Andariel, a North Korean hacking group that is part of Lazarus, a well-known state-sponsored cybercrime organization. Andariel typically gains initial access by exploiting software vulnerabilities or tricking users into downloading malware. Once inside, they use hacking tools like PsExec and JuicyPotato to obtain SYSTEM-level privileges, the highest level of access on a Windows machine.

However, SYSTEM-level access has limitations, such as the inability to log in remotely, lack of persistence after a system restart, and high visibility to security systems. To overcome these, Andariel creates a hidden user account using the Windows "net user" command, adding a "$" symbol at the end of the username to make it invisible in regular user lists. They then modify its RID to that of an administrator, granting it full control over the system while remaining undetected.

How to Defend Against RID Hijacking

To protect against RID hijacking, organizations and IT administrators can take the following steps:

  1. Monitor User Login Activity: Use the Local Security Authority (LSA) Subsystem Service to track unusual logins or permission changes.
  2. Secure Critical System Files: Restrict unauthorized modifications to the SAM registry, where login credentials are stored.
  3. Block Hacking Tools: Prevent tools like PsExec and JuicyPotato from running, as they are commonly used for privilege escalation.
  4. Implement Multi-Factor Authentication (MFA): Require an extra authentication step for all accounts, even low-level ones, to prevent unauthorized access.
  5. Regularly Audit User Accounts: Check for hidden or suspicious accounts, especially those with "$" symbols or unusual RID values.

RID hijacking has been known since 2018, when cybersecurity researchers first demonstrated it as a way to maintain persistent access on Windows systems. However, its recent use by North Korean state-sponsored hackers highlights the growing sophistication of cyberattacks. By making small, undetectable changes to Windows user settings, hackers can silently maintain control over a compromised system, making it much harder for security teams to remove them.

The use of RID hijacking by North Korean hackers underscores the importance of proactive cybersecurity measures. Organizations must monitor user accounts, detect hidden activity, and secure critical system files to defend against such stealthy attacks. By staying vigilant and implementing robust security practices, businesses can better protect their systems from advanced threats like RID hijacking.

Why Securing Online Accounts is Critical in Today’s Cybersecurity Landscape

 

In an era where cybercriminals are increasingly targeting passwords through phishing attacks, data breaches, and other malicious tactics, securing online accounts has never been more important. Relying solely on single-factor authentication, such as a password, is no longer sufficient to protect sensitive information. Multi-factor authentication (MFA) has emerged as a vital tool for enhancing security by requiring verification from multiple sources. Among the most effective MFA methods are hardware security keys, which provide robust protection against unauthorized access.

What Are Hardware Security Keys?

A hardware security key is a small physical device designed to enhance account security using public key cryptography. This method generates a pair of keys: a public key that encrypts data and a private key that decrypts it. The private key is securely stored on the hardware device, making it nearly impossible for hackers to access or replicate. Unlike SMS-based authentication, which is vulnerable to interception, hardware security keys offer a direct, offline authentication method that significantly reduces the risk of compromise.

Hardware security keys are compatible with major online platforms, including Google, Microsoft, Facebook, GitHub, and many financial institutions. They connect to devices via USB, NFC, or Bluetooth, ensuring compatibility with a wide range of hardware. Popular options include Yubico’s YubiKey, Google’s Titan Security Key, and Thetis. Setting up a hardware security key is straightforward. Users simply register the key with an online account that supports security keys. For example, in Google’s security settings, users can enable 2-Step Verification and add a security key.

Once linked, logging in requires inserting or tapping the key, making the process both highly secure and faster than receiving verification codes via email or SMS. When selecting a security key, compatibility is a key consideration. Newer devices often require USB-C keys, while older ones may need USB-A or NFC options. Security certifications also matter—FIDO U2F provides basic security, while FIDO2/WebAuthn offers advanced protection against phishing and unauthorized access. Some security keys even include biometric authentication, such as fingerprint recognition, for added security.

Prices for hardware security keys typically range from $30 to $100. It’s recommended to purchase a backup key in case the primary key is lost. Losing a security key does not mean being locked out of accounts, as most platforms allow backup authentication methods, such as SMS or authentication apps. However, having a secondary security key ensures uninterrupted access without relying on less secure recovery methods.

Maintaining Strong Online Security Habits

While hardware security keys provide excellent protection, maintaining strong online security habits is equally important. This includes creating complex passwords, being cautious with email links and attachments, and avoiding oversharing personal information on social media. For those seeking additional protection, identity theft monitoring services can offer alerts and assistance in case of a security breach.

By using a hardware security key alongside other cybersecurity measures, individuals can significantly reduce their risk of falling victim to online attacks. These keys not only enhance security but also ensure convenient and secure access to their most important accounts. As cyber threats continue to evolve, adopting advanced tools like hardware security keys is a proactive step toward safeguarding your digital life.

T-Mobile Enhances Cybersecurity with Yubikey Security Keys

 

T-Mobile has taken a significant step in enhancing its cybersecurity by adopting Yubikey security keys for its employees. The company purchased over 200,000 security keys from Yubico, deploying them across all staff, vendors, and authorized retail partners. The rollout, which began in late 2023, was completed in under three months, with T-Mobile reporting positive results within the first year of implementation.

Jeff Simon, T-Mobile’s chief security officer, highlighted the rapid deployment and the impact of the security keys. He emphasized their effectiveness in strengthening the company’s defenses against cyber threats. These hardware-based keys address vulnerabilities associated with digital passwords, such as phishing, malware, and brute-force attacks.

Security keys leverage public-key cryptography to securely authenticate users without exposing login credentials to potential attackers. The keys generate and store a private authentication key for online services directly on the physical device. This method ensures that even if hackers attempt to phish for login details, they cannot gain unauthorized access without the physical key.

Starting at around $20, these keys are an affordable and viable option for both individuals and businesses looking to bolster their cybersecurity. Tech giants such as Google, Apple, Facebook, and Coinbase have already adopted similar solutions to protect employees and customers.

T-Mobile’s decision to adopt security keys comes after a history of data breaches, including phishing attacks that compromised login credentials and internal systems. In response to an FCC investigation into these breaches, T-Mobile initially considered implementing multi-factor authentication (MFA) for all employee accounts. However, concerns about sophisticated hackers intercepting MFA codes via compromised smartphones led the company to choose a more secure hardware-based solution.

Enhanced Authentication with Yubico FIDO2 Keys

According to T-Mobile’s senior cybersecurity manager, Henry Valentine, the implementation of Yubico’s FIDO2 security keys has eliminated the need for employees to remember passwords or input one-time passcodes (OTP). Instead, employees authenticate their identity passwordlessly using their YubiKeys, enhancing both security and convenience.

While these security keys provide robust protection against phishing and credential theft, T-Mobile remains vigilant against other cybersecurity threats.

Despite the strengthened security measures, T-Mobile continues to face threats from advanced cyber adversaries. Notably, the Chinese hacking group “Salt Typhoon” has targeted US carriers, including T-Mobile, through software vulnerabilities. However, T-Mobile’s adoption of Yubikeys has helped prevent unauthorized access attempts.

The adoption of Yubikey security keys marks a proactive step in T-Mobile’s ongoing commitment to safeguarding its systems and data. By investing in hardware-based authentication, the company aims to stay ahead of evolving cyber threats and ensure a secure digital environment for its employees and customers.

Why MFA Failures Signal Greater Cybersecurity Challenges

 


In the current cybersecurity era, multi-factor authentication (MFA) is widely recommended and often mandated across several sectors, making it one of the most popular security measures that are available. As stated by the Cybersecurity and Infrastructure Security Agency (CISA), implementing MFA is an easy-to-follow method for safeguarding organizations and reducing the risk of account compromise attacks significantly, thereby ensuring the organization's security. 

Several key guidelines and regulations emphasize the importance of multi-factor authentication (MFA) for improving security protocols in several ways, for example, NIST Special Publication (NIST SP) 800-63-3 stipulates that multi-factor authentication is a requirement for systems requiring authentication assurance levels two and three (AAL). 

As an additional measure of security, Executive Order 14028 directs all government agencies in the United States to adopt multi-factor authentication. Several industry standards, including the Payment Card Industry Data Security Standard (PCI DSS) and the Service Organization Control 2 (SOC 2), also require MFA to secure sensitive data environments, to ensure compliance with these standards, and even though MFA has been widely endorsed, emerging concerns over its vulnerabilities are prompting experts to examine its limitations and potential risks in light of those concerns. As the traditional mechanisms of multi-factor authentication (MFA), which have been widely considered a cornerstone of cybersecurity for many years, are struggling to keep pace with the advancing threats, they are coming under more scrutiny. 

It is becoming increasingly evident that legacy multifactor authentication systems are being circumvented with alarming effectiveness as a result of phishing campaigns, ransomware attacks, and advanced exploitation techniques. MFA has become increasingly vulnerable to sophisticated cyberattacks and these developments raise serious concerns about its reliability as a protection measure. Authentication by multiple factors (MFA) has been a cornerstone of cybersecurity for decades.

It has proven to be a very effective method of strengthening security perimeters against unauthorized access. However, with the relentless evolution of cyber threats, it is imperative that organizations continually evaluate whether it is effective. Emerging vulnerabilities in traditional MFA approaches emphasize the importance of adjusting and evolving the security perimeters. 

As a result, the use of SIM swapping techniques, in which attackers hijack mobile phone numbers to intercept SMS codes, has become increasingly prevalent, resulting in significant financial losses. In addition, authentication fatigue is also a growing challenge, since users who are overwhelmed with frequent prompts may adopt risky behaviors, such as sharing codes or circumventing security protocols, that can lead to significant financial losses. 

Moreover, new forms of exploitation of biometric authentication are becoming available because of advances in artificial intelligence and deep-fake technology. As a result of push notification hijacking and sophisticated account takeover techniques, legacy MFA systems remain vulnerable to exploitation. The vulnerability highlights the need to diversify authentication factors, incorporate risk-based assessments, and leverage advanced threat detection tools to enhance security against these threats. 

A crucial part of modern cybersecurity strategies remains Multi-factor authentication (MFA), but it is not immune from failure; organizations should take proactive measures to strengthen their defenses and educate their users about the threats they are facing. In today's rapidly changing threat landscape, it is imperative to maintain an adaptive and dynamic authentication approach to maintain a resilient security posture. 

Insurers are advised to consider the importance of multi-factor authentication (MFA) when insuring businesses because it directly impacts the level of risk incurred by the business. Providing another layer of security to sensitive systems besides passwords makes MFA a very effective security measure that significantly reduces the likelihood of unauthorized access to sensitive systems. In turn, this reduces the risk of cyberattacks, phishing attempts, account takeovers, and credential stuffing, among other cyber threats. 

As insurers, it is important to know if a company has implemented MFA as well as how effectively it is used so that the overall risk profile can be assessed. Insurance companies can price policies accurately based on this knowledge, ensuring that the policies reflect a company's true security posture. A company's liability liability may be misjudged if insurers do not receive this critical information, leaving them at risk of inadequate coverage or increased claims exposure. The use of multi-factor authentication has been a key way of preventing unauthorized access for years, but it is no longer immune to evolving threats as it has been for years. 

As the frequency of tactics such as SIM swapping increases, the risk of hackers intercepting SMS codes has increased, resulting in significant financial losses for the company. Additionally, authentication fatigue is still a concern, as users may bypass security measures or share MFA codes if they become overwhelmed by constant prompts. As artificial intelligence and deepfake technologies continue to rise, biometric systems are becoming more vulnerable. 

Moreover, push notifications hijacking and account takeover methods illustrate the limitations of legacy multi-factor authentication systems. To deal with these challenges, a variety of authentication factors must be used, dynamic risk assessments must be conducted, and advanced threat detection tools be incorporated. While Multi-factor authentication remains a cornerstone of cybersecurity, organizations should continue to strengthen their defenses and adapt their strategies to stay ahead of emerging threats even though MFA remains a cornerstone. 

Today's increasingly complex technological landscape has made biometric authentication an increasingly challenging process, despite being once hailed as a breakthrough in securing systems where passwords failed to work. As far as fingerprints, facial recognition, and retinal scanners were concerned, they were once considered unique and practically impenetrable, but now deepfake technology has disrupted the perception that these systems are secure. As deepfakes have become more sophisticated, they have been revealing critical flaws in biometric systems that can mimic voices, facial features, and even expressions in real-time.

It is warned that as deepfakes become more common in the business world, organizations will need to adopt additional verification procedures to keep their business environment secure, particularly when conducting sensitive transactions. Approximately one-third of businesses may abandon facial recognition technology altogether by the year 2026, signaling an erosion of trust in biometrics as a whole. In light of the increasing threats from insecure biometrics, organizations must reevaluate their dependence on these technologies and implement robust countermeasures to address them. When stakes continue to rise in cyberspace, it will be imperative to safeguard sensitive systems against exploitation by adapting strategies and implementing layered defenses. 

A significant advancement has been achieved in the field of digital security in the form of the integration of Public Key Infrastructure (PKI) into Multi-Factor Authentication (MFA) systems. In the process of verifying identities through digital certificates, a PKI provides a secure framework for the authentication of users. As cybersecurity threats continue to evolve, PKI's role in enhancing multifactor authentication is gaining prominence. 

PKI guarantees ethe encryption of data transmission and employs digital signatures to guarantee the integrity and authenticity of the data. Based on a study by Orbis Market Reports, it has been projected that PKI will continue to grow in the authentication market, indicating its increasing adoption. Organizations are making progress towards a safer digital environment by combining PKI with adaptive authentication and artificial intelligence. As an integral part of cybersecurity, multifactor authentication plays a critical role, but it is not sufficient by itself to address every risk associated with cybercrime. 

Companies must integrate multifactor authentication with advanced threat detection, ongoing monitoring, and other proactive security measures to build a robust security framework. Layered approaches are essential for combating evolving threats and ensuring comprehensive protection for their systems.

Cloud Security Cryptojacking Cybersecurity Threats Google Cloud MFA Raccoon Stealer Ransomware Technology

TRIPLESTRENGTH Targets Cloud for Cryptojacking, On-Premises Systems for Ransomware Attacks

 

Google unveiled a financially driven threat actor, TRIPLESTRENGTH, targeting cloud environments for cryptojacking and on-premise ransomware operations.

"This actor engaged in a variety of threat activity, including cryptocurrency mining operations on hijacked cloud resources and ransomware activity," Google Cloud noted in its 11th Threat Horizons Report.

TRIPLESTRENGTH employs a three-pronged attack strategy: unauthorized cryptocurrency mining, ransomware deployment, and offering cloud platform access—spanning services like Google Cloud, AWS, Azure, Linode, OVHCloud, and Digital Ocean—to other attackers. The group's primary entry methods involve stolen credentials and cookies, often sourced from Raccoon Stealer logs. Compromised environments are used to create compute resources for mining cryptocurrency using tools like the unMiner application and the unMineable mining pool, optimized for both CPU and GPU algorithms.

Interestingly, TRIPLESTRENGTH has concentrated its ransomware efforts on on-premises systems, deploying lockers such as Phobos, RCRU64, and LokiLocker.

"In Telegram channels focused on hacking, actors linked to TRIPLESTRENGTH have posted advertisements for RCRU64 ransomware-as-a-service and also solicited partners to collaborate in ransomware and blackmail operations," Google Cloud disclosed.

One notable incident in May 2024 involved initial access through Remote Desktop Protocol (RDP), followed by lateral movement and antivirus evasion to execute ransomware across several systems. TRIPLESTRENGTH also regularly advertises access to compromised servers on Telegram, targeting hosting providers and cloud platforms.

To counteract such threats, Google has introduced multi-factor authentication (MFA) and improved logging for detecting sensitive billing actions.

"A single stolen credential can initiate a chain reaction, granting attackers access to applications and data, both on-premises and in the cloud," Google warned. 

"This access can be further exploited to compromise infrastructure through remote access services, manipulate MFA, and establish a trusted presence for subsequent social engineering attacks."

AWS Data Breach LummaC2 malware MFA PowerSchool

PowerSchool Data Breach Exposes Millions

 


An American education technology company, PowerSchool, is the latest giant to fall a victim of hacking and data breaches, which probably compromised millions of records of students and teachers in North America. As one of the leading providers of school records management software, PowerSchool serves 18,000 schools who manage data over 60 million students.


How the breach happened

The compromise was discovered on December 28 and was traced to a subcontractor's account. The new report said, however, that another incident of hacking-a compromise of the access of a PowerSchool software engineer-may have had something to do with the breach. Malware infected the engineer's computer and exfiltrated login credentials for internal systems, such as Slack, AWS, and other tools.

According to the logs retrieved by researchers, the infostealing malware known as LummaC2 was used to steal the engineer's passwords. The malware extracted saved passwords and browsing histories from the web browsers of the engineer and uploaded them to a server run by cybercriminals. The stolen credentials were shared in cybercrime groups, which further exposed PowerSchool's systems. 


What Data Was Stolen?

The hackers accessed a range of sensitive personal information, including:  

  • Social Security numbers  
  •  Student grades and demographics  
  •  Medical information  
  •  Parental access details, such as restraining orders  
  •  Records of students’ medication schedules  

School districts impacted by the breach reported that the attackers stole all historical data stored in PowerSchool’s systems.  

The lack of multi-factor authentication (MFA) on a compromised maintenance account was one key vulnerability. PowerSchool has implemented MFA and reset passwords across its customer support portal. Many of the employee credentials discovered were weak and have been exposed in other breaches.

The breach, which has underlined the threats of infostealing malware in hybrid work setups where employees operate company systems using personal devices, has left much to be expected from PowerSchool.


Response and Investigation

PowerSchool, the company concerned, is reportedly working with a cybersecurity firm named CrowdStrike for the investigation into the incident. According to them, no signs of malware have been found neither has any sign of system-layer access. But they are analyzing the stolen data.


Effects on Schools

Many school districts are operating independently to gauge the scope of the breach, relying on collective knowledge from other administrators. As the investigation continues, there are questions about PowerSchool's security measures and how it managed this extensive breach. 

Schools, parents, and educators are urged to be vigilant and ensure additional layers of security are put in place to prevent future incidents.

Hackers Exploit Microsoft Teams for Phishing and Malware Attacks

 

Cybercriminals are increasingly targeting Microsoft Teams, utilizing the platform for sophisticated phishing, vishing, and ransomware campaigns. Exploiting Teams' widespread use, attackers employ social engineering tactics to deceive users and extract sensitive data. Methods range from fake job offers to malicious file sharing, aiming to infiltrate accounts and compromise organizational networks.

Bypassing Multifactor Authentication

One notable tactic involves bypassing multifactor authentication (MFA). Threat actors, reportedly linked to the SolarWinds attack, create fraudulent “onmicrosoft.com” subdomains designed to mimic legitimate security entities. They send chat requests via Microsoft Teams, prompting users to enter a code into the Microsoft Authenticator app. This action grants attackers unauthorized access to Microsoft 365 accounts, enabling data theft or the integration of malicious devices into corporate networks.

The Black Basta ransomware group employs a different strategy by overwhelming users with spam emails and impersonating IT support staff on Teams. Claiming to assist with email issues, they persuade victims to install remote desktop tools, providing attackers with direct access to deploy malware. This includes Trojans and ransomware designed to exfiltrate sensitive data and compromise systems.

Another prevalent scheme involves fake job offers. Scammers contact individuals with fabricated employment opportunities, sometimes conducting entire interviews via Microsoft Teams chat. These scams often escalate to requests for personal information, such as Social Security numbers or tax details. In some cases, victims are asked to pay for materials or services, resulting in financial loss and potential identity theft.

Attackers also impersonate HR personnel, sending phishing messages about urgent policy updates. These messages frequently include malicious files disguised as legitimate updates. Once downloaded, malware like DarkGate is installed, granting attackers control over the victim’s system and network.

Additionally, compromised Microsoft 365 accounts are used to distribute malicious files through Teams chats. These files often appear as PDFs with double extensions, deceiving users into downloading executable malware. Once activated, these programs can breach data and facilitate deeper network infiltration.

Mitigation Strategies for Organizations and Users

Vigilance is essential in countering these threats. Users should verify unexpected messages, invitations, or file-sharing requests, especially those containing links or urgent calls to action. Tools that check link safety and domain age can help detect phishing attempts.

Organizations should prioritize employee education on recognizing scams and enforcing robust cybersecurity protocols. By staying informed and cautious, users can mitigate risks and safeguard against cyberattacks targeting Microsoft Teams.

Multi-Factor Authentication (MFA)
CISA Cyber Security Cybersecurity measures FBI FIDO Hackers MFA mobile phone Multi-Factor Authentication (MFA)

CISA's Enhanced Mobile Security Recommendations Following U.S. Telecom Breach

 



The Cybersecurity and Infrastructure Security Agency (CISA) issued updated recommendations in December 2024 aimed at enhancing mobile phone cybersecurity. Following a significant hack involving major U.S. telecom companies like AT&T, Verizon, and Lumen Technologies, these guidelines focus on adopting more secure multifactor authentication (MFA) methods. 
  
Understanding MFA and Its Vulnerabilities 
 
Multifactor authentication (MFA) is a popular cybersecurity measure requiring users to provide additional verification beyond a password. Common practices include:
  • Text Message Verification: Receiving a one-time code via SMS.
  • Device-Based Approvals: Confirming login attempts on associated devices.
However, CISA has raised concerns about the vulnerability of certain MFA techniques, particularly text-based verification. Text message-based MFA, while convenient, is susceptible to interception by hackers. 

The breach highlighted flaws in text messaging systems, particularly when messages were sent between incompatible platforms like Android and iPhone. Malicious actors exploited these weaknesses to intercept authentication codes and gain unauthorized access to user accounts. While CISA continues to advocate for MFA, it strongly urges users to shift away from text-based methods. 

  
Recommendations for Safer Alternatives 

 
CISA recommends adopting authenticator apps as a more secure MFA option. These apps generate time-sensitive codes that operate independently of messaging systems, making them less prone to interception. However, they remain vulnerable to phishing attacks, where users may be tricked into revealing sensitive information. 

For users seeking the most secure MFA solution, CISA suggests transitioning to phishing-resistant methods like the FIDO (Fast Identity Online) protocol. Developed by the FIDO Alliance, this technology eliminates traditional passwords and uses:
  • Digital Passkeys: Unique codes linked to user accounts.
  • Physical USB Devices: Hardware keys that connect to computers.
The FIDO protocol also supports PINs and biometric identifiers like fingerprints and facial recognition, providing a robust defense against phishing attempts. 

CISA’s latest recommendations highlight the growing need for stronger cybersecurity measures. By moving away from text-based MFA and adopting secure alternatives like authenticator apps and the FIDO protocol, users can better protect their personal information and maintain digital security in an increasingly interconnected world.

Change Healthcare CISA Cyber Security cybersecurity in healthcare Healthcare Cyberattacks HHS MFA regulatory measures

Proposed US Bill Mandates MFA and Cybersecurity Standards for Healthcare

 

A bipartisan group of US senators has introduced new legislation aimed at strengthening cybersecurity in American hospitals and healthcare organizations. The Health Care Cybersecurity and Resiliency Act of 2024 seeks to mandate the adoption of multi-factor authentication (MFA) and establish minimum cybersecurity standards to protect sensitive health information and ensure system resilience against cyberattacks. 

The proposed law, unveiled by Senators Bill Cassidy (R-Louisiana), Mark Warner (D-Virginia), John Cornyn (R-Texas), and Maggie Hassan (D-New Hampshire), aims to improve coordination between the Department of Health and Human Services (HHS) and the Cybersecurity and Infrastructure Security Agency (CISA). Under this legislation, HHS would have a year to develop a comprehensive cybersecurity incident response plan and update the breach reporting portal with additional transparency requirements. 

Currently, healthcare entities classified as “covered entities” under HIPAA are obligated to report breaches to HHS. The new legislation expands these requirements, compelling organizations to disclose the number of individuals affected by a breach, corrective actions taken, and recognized security practices considered during investigations. The HHS secretary would have discretion to add further information to the portal as needed. In addition to enforcing MFA and encrypting protected health information, the bill outlines broader cybersecurity mandates. Covered entities and their business associates would need to adopt minimum standards defined by HHS, conduct regular audits, and perform penetration testing to validate their security measures. 

Senator Cassidy, a medical doctor and ranking member of the Senate Health, Education, Labor, and Pensions (HELP) Committee, underscored the urgency of this legislation. “Cyberattacks on our healthcare sector not only put patients’ sensitive health data at risk but can delay life-saving care,” Cassidy emphasized. The devastating impact of cyberattacks on healthcare was exemplified earlier this year when a ransomware gang targeted Change Healthcare, compromising sensitive health data from approximately 100 million individuals. 

The attack disrupted healthcare services nationwide and cost the UnitedHealth-owned company over $2 billion in remediation efforts, taking nine months to restore its operations. This high-profile incident spurred additional legislative action. Senators Warner and Ron Wyden (D-Oregon) proposed another bill earlier this year to establish mandatory minimum cybersecurity standards for healthcare providers and related organizations. 

 If enacted, the Health Care Cybersecurity and Resiliency Act would mark a significant step in fortifying the healthcare sector’s defenses against cyber threats, ensuring the security of patient data and the continuity of critical healthcare services.

Google Cloud to Enforce Multi-Factor Authentication for Enhanced Security in 2025

 


As part of its commitment to protecting users' privacy, Google has announced that by the end of 2025, all Google Cloud accounts will have to implement multi-factor authentication (MFA), also called two-step verification. Considering the sensitive nature of cloud deployments and the fact that phishing and stolen credentials remain among the top attack vectors observed by Mandiant Threat Intelligence, it seems likely that Google Cloud users should now be required to perform [2 steps of verification], as Mayank Upadhyay, Google Cloud's VP of Engineering and Distinguished Engineer, told the audience. 

By the end of 2025, Google's cloud division is planning to introduce an optional multi-factor authentication (MFA) feature for all users, as part of its efforts to improve account security as a part of its mission to improve security across the company. As part of a recent announcement by the tech giant, it was announced that it will begin the transition with a phased rollout, to help users adapt more smoothly to the changes. 

The technology industry and cyber security industry have long recommended multifactor authentication as a highly secure authentication method. With an additional step of verification, multi-factor authentication (MFA) dramatically reduces the risk of unauthorized logins, data breaches, and account takeovers, regardless of whether the user's password is compromised. As hackers continue to ramp up their sophisticated attacks on cloud infrastructure and sensitive data, Google is pushing for mandatory MFA as part of a growing trend in cybersecurity. 

According to recent announcements, Google is planning on requiring multi-factor authentication (MFA) for all Cloud accounts by the end of 2025, to protect cloud accounts. MFA is supposed to strengthen security while maintaining a smooth and convenient user experience online, which is exactly what Google claims. It has been reported that 70% of Google users have started using this feature and that security consultants are urging those users who are still on the fence to switch over to MFA at once. Users as well as admins who have access to Google Cloud will be affected by the implementation of the new process. 

Generally speaking, this change will not impact Google accounts of general consumer users. In a recent announcement sent made by Mayank Upadhyay, Google Cloud's VP of Engineering and Distinguished Engineer an official announcement the company stated that they plan to have mandatory MFA implemented throughout 2025 in a phased approach, with assistance being provided to help plan the deployment process. In response to Google's announcement, the company now states that it is taking a phased approach to the mandatory 2FA requirement that will apply to Google Cloud users; here's what that means in practice. 

There will be three phases to the implementation, and the first phase begins immediately with Google encouraging users to adopt 2FA if they have not yet had the chance to install 2FA protection on their account, but currently sign in with a password. Google estimates that 70% of online users have done this. As part of the first phase of the program, which is scheduled to begin in November 2024, the aim will be to encourage the adoption of MFA. The Google Cloud console will be regularly updated with helpful reminders and information. Resources will be available to help raise awareness, plan rollout and documentation of the MFA process, as well as to conduct testing and enable MFA for users with ease. The first phase of the project is scheduled to begin in November 2024 and will play a key role in facilitating the adoption of MFA. 

There will be several notes and reminders in the Google Cloud Console, including information you'll find helpful in raising awareness, planning rollouts, conducting tests, and ensuring that MFA is enabled smoothly for users, to help raise awareness. There will be a second phase that begins early next year and, at the start of the year, Google will start requiring MFA for users who sign in to Google Cloud with a password, whether they are new or existing. Nevertheless, Google has not yet expressed a concrete date for when it is planning to deploy the 2FA technology as part of phase two, which is scheduled for "early 2025". 

It is important to note, however, that all new Google Cloud users, whether or not they already have a password, will be required to implement two-factor authentication to sign in. As of now, this is a mandatory requirement, with no ifs, no buts. As soon as the Google Cloud Console, Firebase Console and iCloud are updated with the 2FA notification, Upadhyay will warn users that to continue using those tools, they need to enrol with the 2FA service. The final phase of Google Cloud's 2FA requirement will be rolled out by the end of 2025, it has been told and will be required for all users currently using federated authentication when logging into Google Cloud by that time. 

It was confirmed in the announcement that there will be flexible options for meeting this requirement. In other words, it appears to be an option for users to enable 2FA with their primary identity provider before accessing Google Cloud itself, or to add a layer of security through Google's system, using their Google account to enable 2FA through their cloud service. A senior director of technical field operations at Obsidian Security told me that the threat landscape has rapidly become more sophisticated as a result of this increased MFA prevalence. The breach data shows that 89% of compromised accounts have MFA enabled, according to Chris Fuller, senior director of technical field operations.

Several phishing-as-a-service toolkits, including the Mamba toolkit that you can buy for $250 a month, as well as non-human identity compromises, suggest that identity compromises will continue regardless of the technology used to carry out." Google's phased rollout is designed to ease users into the new requirement, which could have been met with resistance due to perceived friction in the user experience, especially when the requirement is implemented suddenly," Patrick Tiquet, Vice President of Security and Compliance at Keeper Security, said. Tiquet further emphasized that organizations leveraging Google Cloud will need to strategically prepare for MFA implementation across their workforce. 

This preparation includes comprehensive employee training on the critical role of multi-factor authentication in safeguarding organizational data and systems. Effective MFA adoption may be supported by tools such as password managers, which can streamline the process by securely storing and automatically filling MFA codes. Proper planning and training will be essential for organizations to successfully integrate MFA and enhance security measures across their teams.

Threat Detection
2024 Authentication Cyber Fraud CyberCrime Cybersecurity Mamba 2FA MFA phishing phishing-as-a-service SEKOIA Telegram Threat Detection

Mamba 2FA Emerges as a New Threat in Phishing Landscape

 

In the ever-changing landscape of phishing attacks, a new threat has emerged: Mamba 2FA. Discovered in late May 2024 by the Threat Detection & Research (TDR) team at Sekoia, this adversary-in-the-middle (AiTM) phishing kit specifically targets multi-factor authentication (MFA) systems. Mamba 2FA has rapidly gained popularity in the phishing-as-a-service (PhaaS) market, facilitating attackers in circumventing non-phishing-resistant MFA methods such as one-time passwords and app notifications.

Initially detected during a phishing campaign that imitated Microsoft 365 login pages, Mamba 2FA functions by relaying MFA credentials through phishing sites, utilizing the Socket.IO JavaScript library to communicate with a backend server. According to Sekoia's report, “At first, these characteristics appeared similar to the Tycoon 2FA phishing-as-a-service platform, but a closer examination revealed that the campaign utilized a previously unknown AiTM phishing kit tracked by Sekoia as Mamba 2FA.” 

The infrastructure of Mamba 2FA has been observed targeting Entra ID, third-party single sign-on providers, and consumer Microsoft accounts, with stolen credentials transmitted directly to attackers via Telegram for near-instant access to compromised accounts.

A notable feature of Mamba 2FA is its capacity to adapt to its targets dynamically. For instance, in cases involving enterprise accounts, the phishing page can mirror an organization’s specific branding, including logos and background images, enhancing the believability of the attack. The report noted, “For enterprise accounts, it dynamically reflects the organization’s custom login page branding.”

Mamba 2FA goes beyond simple MFA interception, handling various MFA methods and updating the phishing page based on user interactions. This flexibility makes it an appealing tool for cybercriminals aiming to exploit even the most advanced MFA implementations.

Available on Telegram for $250 per month, Mamba 2FA is accessible to a broad range of attackers. Users can generate phishing links and HTML attachments on demand, with the infrastructure shared among multiple users. Since its active promotion began in March 2024, the kit's ongoing development highlights a persistent threat in the cybersecurity landscape.

Research from Sekoia underscores the kit’s rapid evolution: “The phishing kit and its associated infrastructure have undergone several significant updates.” With its relay servers hosted on commercial proxy services, Mamba 2FA effectively conceals its true infrastructure, thereby minimizing the likelihood of detection.

Fortinet Cybersecurity Breach Exposes Sensitive Customer Data

 

Fortinet experienced a significant cybersecurity breach involving a third-party cloud drive, where 440 GB of data was leaked by a hacker named “Fortibitch” after the company refused to pay the ransom. The breach affected about 0.3% of Fortinet’s customers, roughly 1,500 corporate users, and included sensitive information such as financial documents, HR data, customer details, and more. Experts highlight that the breach underscores the critical need for implementing rigorous cybersecurity measures like multi-factor authentication (MFA) and robust identity access management (IAM) systems. 

Multi-factor authentication is particularly emphasized as a vital layer of defense against unauthorized access, significantly reducing the risk of data exposure when combined with strong identity access management. Organizations need to ensure that they enforce MFA and other identity management protocols consistently, especially for accessing essential systems like SharePoint and cloud storage services. Jim Routh, Chief Trust Officer at Saviynt, pointed out the growing concern over cloud security, given its increased adoption in software development and data storage. He stressed that without proper safeguards, such as MFA and secure access controls, sensitive data is at risk of exposure. 

Cybersecurity analyst Koushik Pal from CloudSEK echoed this sentiment, advocating for stricter IAM policies and urging organizations to regularly monitor repositories for potential misconfigurations, exposed credentials, or sensitive data leaks. This kind of vigilance is necessary for all teams to adhere to security best practices and minimize vulnerabilities. Relying on third-party vendors for data storage, as Fortinet did, is not inherently dangerous but introduces additional risks if strict security protocols are not enforced. The breach serves as a reminder that even established cybersecurity companies can fall victim to attacks, highlighting the need for ongoing vigilance. 

According to Routh, it’s crucial for system administrators to manage accounts meticulously, ensuring that identity access management protocols are properly configured and that privileged access is monitored effectively. The breach exemplifies how cybercriminals exploit security weaknesses to gain unauthorized access to sensitive data. As cloud technologies continue to be integrated into businesses, the responsibility to protect data becomes increasingly important. Cybersecurity experts emphasize that organizations must invest in proper training, regularly update security measures, and remain vigilant to adapt to evolving cyber threats. 

Ensuring that MFA, identity management systems, and monitoring practices are in place can go a long way in protecting against similar breaches in the future. This Fortinet incident serves as a wake-up call, showing that no organization is entirely immune to cyber threats, regardless of its expertise in cybersecurity.

Cybernews Data Breach Healthcare Healthcare Breach MFA Personal Data SSNs

Florida Healthcare Data Leak Exposes Thousands of Doctors and Hospitals

 

A data breach at Florida-based recruitment firm MNA Healthcare has left sensitive information of over 14,000 healthcare workers and 10,000 hospitals exposed. Discovered on June 20, 2024, by the Cybernews research team, the breach was caused by a misconfiguration that left a database backup publicly accessible online. The database contained sensitive data, including full names, addresses, phone numbers, work experience, encrypted Social Security Numbers (SSNs), and hashed passwords.

The encryption used for the SSNs was found to be vulnerable due to an exposed environment file containing the Laravel App Key, which is used for encrypting SSNs. While encrypted, researchers indicated that decrypting the SSNs is possible, putting affected healthcare workers at risk of identity theft and fraud. The exposed data is particularly concerning because healthcare professionals are often targeted by cybercriminals, as their high salaries make them attractive for financial fraud.

MNA Healthcare is a staffing firm that operates in nine U.S. states, matching healthcare professionals with various organizations. Among the leaked information were communications between medical staff and MNA representatives, job assignments, and license copies. This breach puts not only doctors and healthcare workers at risk of identity theft, but also opens up opportunities for credential stuffing and phishing attacks.

The exposed data also increases the possibility of criminals using stolen SSNs to engage in fraudulent activities such as filing false tax returns, opening credit accounts, and misusing the information to obtain loans or benefits. As the leaked database included names of hospitals and medical institutions, these entities could also face reputational damage and potential legal ramifications.

To prevent future breaches like the one at MNA Healthcare, companies must implement more robust cybersecurity measures. One essential step is ensuring that databases containing sensitive information, such as SSNs and other personal data, are encrypted using stronger, more up-to-date encryption methods. Regular security audits should be conducted to detect any misconfigurations or vulnerabilities in their systems before malicious actors can exploit them.

Another crucial step is implementing stricter access controls and monitoring systems. Limiting access to sensitive data to only necessary personnel and tracking any unusual access attempts or data transfers can help detect a breach early. Additionally, using multi-factor authentication (MFA) for employees accessing critical systems adds an extra layer of security, making it harder for unauthorized individuals to infiltrate the system. Finally, companies should also educate their employees about cybersecurity risks and how to recognize phishing scams to minimize the risk of human error leading to data breaches.

Following the discovery of the breach, MNA Healthcare secured the exposed configuration, but concerns remain about the company’s overall infrastructure security. Security expert Aras Nazarovas pointed out that the backup and encryption issues raise questions about how the company stores sensitive information. 

The healthcare sector remains a popular target for cyberattacks, and this breach highlights the need for stronger cybersecurity practices in protecting personal information. Affected individuals are advised to monitor their financial accounts and consider identity theft protection to mitigate potential risks.

SonicWall
Akira Ransomware Cyber Attacks MFA Ransomware SonicWall

Hackers Use SonicWall Security Flaw in Ransomware Attacks


 

In the latest ransomware attack, operators have started using a critical bug in SonicWall SonicOS firewall devices as an entry point for compromising business networks. The vulnerability, identified as CVE-2024-40766, is from the management access interface of the firewall and thus impacts all current devices spanning across Generation 5, Generation 6, and Generation 7. A patch was issued by SonicWall on August 22 to address the issue and asked its users to update their appliances. It later turned out that the same weakness also affects the SSLVPN feature of the devices, which has recently been exploited in the wild.

Arctic Wolf security researchers reported that operators of the Akira ransomware strain have been leveraging the bug for initial access to business networks. These appeared to be the types of attacks that involved compromised accounts, local to the affected devices and independent of centralised authentication systems such as Microsoft Active Directory. What's more, the affected accounts were noted to have MFA disabled, further compromising them. The affected breached devices were running firmware versions in the range vulnerable to CVE-2024-40766.

Apart from Arctic Wolf's discovery, the incidents of ransomware groups making their ways into SonicWall SSLVPN accounts were also reported by the security firm Rapid7. While the incidents being connected to the vulnerability CVE-2024-40766 are purely speculative, the company has underlined the need to take precautions.

Immediate Security Recommendations

The cybersecurity researchers at SonicWall, Arctic Wolf, and Rapid7 have strongly recommended that the administrators take to the immediate implementation of the latest SonicOS firmware updates. Specifically, SonicWall has advised customers to allow access to the Firewall management and SSLVPN features only from trusted sources and block it from the internet, if possible. It has also underlined the implementation of MFA for all SSLVPN users by leveraging the use of TOTP or email-based authentication.

Given the threat, this vulnerability has been added to the Known Exploited Vulnerabilities catalogue by the U.S. Cybersecurity and Infrastructure Security Agency, or CISA. Federal agencies were directed to patch their vulnerable SonicWall devices before September 30, according to Binding Operational Directive, or BOD 22-01. That is the gravity of this vulnerability and how urgently the organisations need to act.

SonicWall Devices Targeted in Previous Attacks

SonicWall devices have been routine targets in the past, due to which the hackers exploit security flaws and gain entry to the corporate networks. For instance, suspected Chinese hackers installed malware on SonicWall Secure Mobile Access (SMA) devices, which persists on firmware upgrades. The Ransomware groups-HelloKitty, FiveHands, and now Akira-keeps exploiting similar vulnerabilities in the SonicWall systems for attacks.

Given that SonicWall serves over 500,000 customers, including government agencies and major corporations worldwide, the pervasive nature of these vulnerabilities calls for timely patching and stout security practices. "The company has urged that all users of the affected products must apply the latest updates in order to protect their systems against future attacks.

Protecting Against Fog Ransomware: Key Strategies and Insights

 

In August 2024, a mid-sized financial firm was targeted by a ransomware attack using compromised VPN credentials to deploy a variant called “Fog” on both Windows and Linux systems. Fortunately, the attack was detected and neutralized by Adlumin’s innovative technology, which uses decoy files as sensors to detect ransomware activity. Fog, a variant of the STOP/DJVU ransomware family first observed in 2021, exploits compromised VPN credentials to breach networks and often targets sectors like education and recreation. 

Once inside, the ransomware uses techniques such as pass-the-hash attacks to escalate privileges, disable security mechanisms, encrypt critical files like Virtual Machine Disks (VMDKs), and delete backup data. Victims are usually directed to a negotiation platform on the Tor network through a ransom note. The lack of direct ties to known threat groups suggests that Fog may originate from a new, highly skilled actor. The attackers initiated their operation by pinging endpoints and using tools like “Advanced Port Scanner” for network reconnaissance. 

They then moved laterally through the network using compromised service accounts, mapped network drives, and harvested credentials. For execution, they used the open-source tool ‘Rclone’ to transfer data and deployed ‘locker.exe’ to encrypt files. Additionally, they deleted system backups to prevent victims from restoring their data. Adlumin’s Ransomware Prevention feature played a critical role in neutralizing the attack. This technology, launched in April 2024, uses decoy files that lie dormant until ransomware activity is detected, triggering the automatic isolation of affected machines and blocking further data theft. 

The feature alerts security teams for a deeper investigation, representing a significant advancement in the fight against ransomware. After isolating compromised systems, security engineers conducted a thorough analysis to identify vulnerabilities and restore the affected systems. In the aftermath of the attack, several key measures were recommended to prevent future incidents: ensuring all VPN connections require Multi-Factor Authentication (MFA), keeping VPN software up to date, monitoring VPN access for unusual activity, and deploying automated isolation procedures when ransomware is detected. 

It is also important to protect endpoints with comprehensive security platforms capable of real-time threat monitoring and response, limit administrative privileges, conduct regular security audits, and establish effective incident response plans. Additionally, organizations should regularly back up critical data in secure environments and monitor network traffic for signs of unusual or malicious activity. These proactive steps help organizations prepare for and mitigate the impact of sophisticated ransomware threats like Fog.
