ALPHV/BlackCat Change Healthcare cyber attack Ransomware United Health

Ransomware Attack Targets Healthcare Giant, Change Healthcare

 


A recent cyberattack on Change Healthcare, a subsidiary of United Health, has led to a distressing data extortion situation, further complicating an already tumultuous ordeal. Let's delve into the details to understand the gravity of the situation and its potential repercussions.


Background

In February, Change Healthcare fell victim to a cyberattack, causing significant disruptions in the US healthcare system. The attack, attributed to the BlackCat/ALPHV ransomware operation, resulted in the theft of approximately 6 TB of data.


Double Extortion Tactics

Following intense pressure from law enforcement, the BlackCat gang abruptly shut down their operation amidst allegations of an exit scam. Subsequently, an affiliate named "Notchy" joined forces with the RansomHub gang to engage in a double extortion scheme against Change Healthcare. Despite rumours of a ransom payment, the threat actors are now threatening to release the stolen data unless their extortion demands are met.


Data Leak and Implications

Screenshots of purportedly stolen data, including corporate agreements and sensitive patient information, have begun circulating online. The leaked information not only jeopardises the privacy of individuals but also raises concerns about potential financial repercussions for Change Healthcare and its affiliates.


Response and Investigation

Change Healthcare has refrained from commenting on the situation, leaving many questions unanswered. Meanwhile, the Department of Health and Human Services has launched an investigation into the incident to assess potential breaches of healthcare data regulations.


Financial Fallout

The fallout from the cyberattack has hit hard financially, with UnitedHealth Group revealing substantial losses of $872 million during the first quarter of this year. These losses cover not only the direct costs of responding to the attack but also the wider disruptions it caused across the company's operations. Additionally, the timing of public sector cash receipts has been affected, further exacerbating the financial impact. Furthermore, UnitedHealth Group disclosed that it had advanced approximately $3 billion to healthcare providers whose finances were disrupted by the attack.


With data security at the forefront of public discourse, it underscores the growing threat posed by ransomware attacks in critical sectors such as healthcare. The need for robust cybersecurity measures and proactive response strategies has never been more apparent, as organisations grapple with the devastating consequences of data breaches and extortion attempts.

India's Businesses Under Huge Cyber Threats, Kaspersky Reported

Indian businesses are being warned about the looming threat of ransomware attacks by cybersecurity experts. These attacks not only jeopardize company data but also pose a serious risk to user information. To address this urgent issue, experts stress the importance of promptly implementing advanced threat intelligence and industrial cybersecurity solutions. 

Kaspersky, a prominent cybersecurity firm, sheds light on the severity of the situation through their research findings. They indicate that ransomware attacks expected in 2024 could result in significant financial losses similar to those experienced in 2023. This underscores the vulnerability of both IT and operational systems within Indian companies, urging them to take proactive steps to defend against potential cyber threats. 

India's vast user base and thriving enterprises have become prime targets for cybercriminals, as per insights from Kaspersky. The cybersecurity firm reveals that India consistently ranks among the top 12 targeted countries and territories for Advanced Persistent Threats (APTs) globally. 

Kaspersky's data underscores ransomware as the predominant cyber threat in 2024. The company points out that the increasing adoption of digital platforms within Indian organizations has stretched the local ICT supply chain, exposing visible vulnerabilities that attract cyberattacks. 

According to Kaspersky, following are Current Challenges Faced by Organizations in India: 

Escalation of Cyberthreats: The advent of the digital age has exposed organizations to heightened vulnerabilities, underscoring the critical importance of cybersecurity. India grapples with a wide array of cyber threats, spanning from financial fraud and data breaches to sophisticated cyber espionage campaigns. 

Varied Attack Methods: Given its expansive population, India serves as a fertile ground for cybercriminals who employ diverse tactics such as phishing, ransomware, and social engineering to infiltrate systems and networks. 

Sector-Specific Targets: Certain sectors, including financial institutions, e-commerce platforms, and government entities, find themselves particularly susceptible to cyberattacks due to the sensitive nature of the data they handle. 

Surge in Ransomware Attacks: The proliferation of ransomware incidents has witnessed a dramatic surge, resulting in significant disruptions to businesses that endure downtime ranging from several days to weeks.

The High Cost of Neglecting Backups: A Ransomware Wake-Up Call

 


Ransomware attacks are becoming increasingly costly for businesses, with a new study shedding light on just how damaging they can be. According to research from Sophos, a staggering 94% of organisations hit by ransomware in 2023 reported attempts by cybercriminals to compromise their backups. This alarming trend poses a significant threat to businesses, as compromised backups can lead to a doubling of ransom demands and payments compared to incidents where backups remain secure.

The impact is particularly severe for certain sectors, such as state and local government, the media, and the leisure and entertainment industry, where 99% of attacks attempted to compromise backups. Perhaps most concerning is the revelation that overall recovery costs can skyrocket when backups are compromised, with organisations facing recovery costs up to eight times higher than those whose backups remain unaffected.

To mitigate the risk of falling victim to ransomware attacks, businesses are urged to take proactive measures. First and foremost, it's essential to backup data frequently and store backups securely in a separate physical location, such as the cloud, to prevent them from being compromised alongside the main systems. Regularly testing the restoration process is also crucial to ensure backups are functional in the event of an attack.

Furthermore, securing backups with robust encryption and implementing layered defences to prevent unauthorised access is essential for ransomware defence. Vigilance against suspicious activity that could signal attackers attempting to access backups is also recommended.

While it's tempting to believe that your organisation won't be targeted by ransomware, the reality is that it's not a matter of if, but when. Therefore, taking proactive steps to secure backups and prepare for potential attacks is imperative for businesses of all sizes.

For businesses seeking additional guidance on ransomware remediation, you can follow this step-by-step guide in order to navigate the recovery process. This Ransomware Defender solution aims to minimise the impact of data breaches and ensure business continuity by storing backups in a highly secure environment isolated from the main infrastructure.

The threat of ransomware attacks targeting backups is real and growing, with significant implications for businesses' financial, operational, and reputational security. By implementing robust backup strategies and proactive defence measures, organisations can better protect themselves against the rising tide of ransomware attacks.

Data Breach Data Theft IoT IT OT Ransomware Waterfall Security

Rise of Hacktivist Groups Targeting OT Systems

Recent research from Waterfall Security Solutions has revealed important insights into the changing nature of cyberattacks on Operational Technology (OT) organizations. One key finding is the rise of hacktivist groups as major players in targeting OT systems. 

Additionally, the study emphasizes that most disruptions in OT environments do not occur directly through manipulation of OT systems but rather as a result of IT-based attacks, particularly ransomware incidents. In simpler terms, hackers are increasingly using ransomware to disrupt OT operations, and these disruptions are causing significant problems for OT organizations. 

Let’s Understand Operational Technology 

Operational Technology (OT) involves using both hardware and software to control industrial equipment, focusing on how it interacts with the physical world. This includes systems like programmable logic controllers (PLCs), distributed control systems (DCSs), and supervisory control and data acquisition (SCADA) systems. 

OT environments are responsible for overseeing and managing real-world processes in industries like manufacturing, energy, healthcare, building management, and environmental systems. 

Differences Between OT, IT, and IOT 

The blending of Operational Technology (OT) and Information Technology (IT) is changing industries in the era of the Internet of Things (IoT). OT deals with managing physical equipment, while IT deals with data systems. IoT connects ordinary objects to the internet, allowing smooth communication and automation. This merging presents fresh chances for making processes more efficient and fostering innovation in various fields. 

Following the report, it highlights a worrying trend a nearly 20% rise in cyberattacks causing physical consequences. 

As per report, last year, cyber incidents inflicted hefty financial blows on companies like Johnson Controls and Clorox, racking up costs of approximately $27 million and $49 million, respectively. In Massachusetts, MKS Instruments faced a staggering $200 million loss due to a cyberattack that halted its operations temporarily. Moreover, its supplier, Applied Materials Inc. based in California, reported an additional loss of $250 million stemming from the same incident. 

Further it reveals that only about 25% of cyberattacks cause problems for operational technology (OT) but instead compromise other parts of the network infrastructure directly. Various attacks happen by compromising machines in the IT network. 

Andrew Ginter, from Waterfall, explains that companies often shut down their OT systems as a precaution when there is a risk of nearby compromised processes. For example, Hahn Group GmbH turned off its systems after an attack last March, leading to weeks of recovery work. Similarly, UK Royal Mail had printers hijacked to print ransom notes, resulting in nationwide mail export suspensions and £42 million in losses. 

Furthermore, Ginter points out if there is a problem with the IT network, it can affect the OT network and vice versa, potentially leading to disruptions in physical operations that rely on these networks.

Behind the LockBit Takedown: Strategies and Significance

 


It was widely hailed as a major victory for law enforcement to take down LockBit in the sprawling war against ransomware and was considered one of the most important victories for law enforcement. However, after law enforcement takes down ransomware groups, they usually reemerge, albeit with less power to continue their criminal activity. 

There was a back-and-forth tussle between law enforcement and the AlphV ransomware group in December when the group resurfaced on the dark web hours after being taken down by the police. As of today, AlphaV has been active for over ten years and lists new victims on its data leak site. 

Over the past decade, ransomware has become an increasingly prevalent problem worldwide, with modern ransomware gangs running complex businesses, and governments and private companies working together to stop these gangs have been working together for the past year. As a part of Operation Cronos, LockBit's infrastructure was used by the coordinating organizations involved with the operation to publish information about the gang's activities. 

There is no doubt that this activity against LockBit is an important victory, but ransomware continues to be a major threat, even from LockBit. To combat ransomware better, cybersecurity communities need to reflect on some lessons learned to improve the fight against ransomware. There have been instances where a victim has paid LockBit but has yet to receive the data that they promised was deleted from their servers, according to the UK's National Crime Agency (NCA). 

As a result of this, a victim trusts that the criminal will keep their end of the bargain after paying the ransom. This is one of the top risks associated with paying a ransom. The disclosure that LockBit failed to delete the data as promised severely tarnished its reputation. If a ransomware group appears trustworthy, its victims will not be willing to pay. 

Organizations need to be prepared for such eventualities and have plans in place in case of such an event. When a company's data is compromised, it needs to prioritize the creation of a thorough disaster recovery plan and procedure in case of data loss or damage, rather than relying on decryption for the sake of recovery. In response to a law enforcement takedown last week, which resulted in police seizing both LockBit's cyber extortion operations and its darknet site, as well as receiving significant intelligence, the criminals are attempting to relaunch their cyber extortion operation. 

The group's administrator, LockbitSupp, launched a new extortion site on Saturday that contains the names and contact information of five victim companies they are threatening to leak stolen documents. Even so, the site is no longer showing any of the old listings from before the law enforcement operation occurred.

Since its launch four years ago, this prolific ransomware-as-a-service outfit has hosted more than 2,000 documents that have been stolen from its victims. Last Monday, police posted a splash page to the dark web that said that they were in control, the most of any of the several extortion gangs operating on it. A week after LockBit's .onion website was hijacked by the U.K. National Crime Agency (NCA), the gang parodied LockBit's infrastructure in a series of posts about how the police had possessed “unprecedented technological access” to the company's infrastructure. 

To downplay the extent of the access, the ransomware service attempted to downplay it. The arrests of alleged affiliates as well as the shutting down of 14,000 accounts on third-party services have come as a result of the ransomware gang's failure to destroy the data of victims, even after it promised to. In an attempt to minimize the reputational damage caused by police action, a new LockBit post attempts to minimize the damage caused by the action. 

The criminals repeat what they claim in the beginning that police had compromised outdated PHP servers. To counter ransomware-as-a-service (RaaS), agencies will resort to a two-fold attack: first, to disrupt the administrative staff of the gang, and then to disrupt its affiliates. It is generally the task of the administrative staff to manage the data leak site, and the task of the affiliates to deploy the ransomware and encrypt networks is the task of the affiliates. 

There is a significant part of the administration staff that enables criminals, and without them being removed, there will be many more criminals assisting them. A disruption of the administration staff will result in the affiliates of the ransomware gangs working for other ransomware gangs. Infrastructure is used by affiliates themselves, either by purchasing it or by illegally accessing it. 

The tools, network connections, and behaviours of this infrastructure provide a considerable amount of information about this infrastructure. The ransom process exposes some details about the administrators: For the ransom process to proceed, the administrator must provide a method of communication and a method of payment for the ransom to be paid. 

The significance of these details may not seem useful to an organization immediately, but law enforcement and researchers will be able to leverage these details to uncover more about the individuals who committed these crimes. Using details from past incidents, law enforcement was able to disrupt LockBit's infrastructure as well as some affiliates of the group by using information from past incidents. 

Likely, Operation Cronos could not have been undertaken without that information, which was gathered with the assistance of attack victims and the allied agencies of the governmental organizations. The fact that an organization does not need to be a victim to help is an important thing to remember. Private organizations are eager to work with governments and are eager to collaborate with them. 

By partnering with CISA, the US government division that formed the Joint Cyber Defense Collaborative (JCDC) to create a global partnership platform to share critical and timely information to fight ransomware, organizations in the US can contribute to the effort to fight ransomware. Government agencies and public organizations can share information through the JCDC in a bidirectional manner. 

To stay on top of emerging trends as well as identify the infrastructure being used by attackers, CISA and organizations work together. There are several ways in which law enforcement can take advantage of collaboration and information sharing to gain a critical advantage against even the most powerful attacker groups, as the LockBit takedown demonstrated.

Enterprise AI Adoption Raises Cybersecurity Concerns

 




Enterprises are rapidly embracing Artificial Intelligence (AI) and Machine Learning (ML) tools, with transactions skyrocketing by almost 600% in less than a year, according to a recent report by Zscaler. The surge, from 521 million transactions in April 2023 to 3.1 billion monthly by January 2024, underscores a growing reliance on these technologies. However, heightened security concerns have led to a 577% increase in blocked AI/ML transactions, as organisations grapple with emerging cyber threats.

The report highlights the developing tactics of cyber attackers, who now exploit AI tools like Language Model-based Machine Learning (LLMs) to infiltrate organisations covertly. Adversarial AI, a form of AI designed to bypass traditional security measures, poses a particularly stealthy threat.

Concerns about data protection and privacy loom large as enterprises integrate AI/ML tools into their operations. Industries such as healthcare, finance, insurance, services, technology, and manufacturing are at risk, with manufacturing leading in AI traffic generation.

To mitigate risks, many Chief Information Security Officers (CISOs) opt to block a record number of AI/ML transactions, although this approach is seen as a short-term solution. The most commonly blocked AI tools include ChatGPT and OpenAI, while domains like Bing.com and Drift.com are among the most frequently blocked.

However, blocking transactions alone may not suffice in the face of evolving cyber threats. Leading cybersecurity vendors are exploring novel approaches to threat detection, leveraging telemetry data and AI capabilities to identify and respond to potential risks more effectively.

CISOs and security teams face a daunting task in defending against AI-driven attacks, necessitating a comprehensive cybersecurity strategy. Balancing productivity and security is crucial, as evidenced by recent incidents like vishing and smishing attacks targeting high-profile executives.

Attackers increasingly leverage AI in ransomware attacks, automating various stages of the attack chain for faster and more targeted strikes. Generative AI, in particular, enables attackers to identify vulnerabilities and exploit them with greater efficiency, posing significant challenges to enterprise security.

Taking into account these advancements, enterprises must prioritise risk management and enhance their cybersecurity posture to combat the dynamic AI threat landscape. Educating board members and implementing robust security measures are essential in safeguarding against AI-driven cyberattacks.

As institutions deal with the complexities of AI adoption, ensuring data privacy, protecting intellectual property, and mitigating the risks associated with AI tools become paramount. By staying vigilant and adopting proactive security measures, enterprises can better defend against the growing threat posed by these cyberattacks.

Ransomware Strikes Tarrant Appraisal District

 



Tarrant Appraisal District (TAD) finds itself grappling with a major setback as its website falls prey to a criminal ransomware attack, resulting in a disruption of its essential services. The attack, which was discovered on Thursday, prompted swift action from TAD, as the agency collaborated closely with cybersecurity experts to assess the situation and fortify its network defences. Following a thorough investigation, TAD confirmed that it had indeed fallen victim to a ransomware attack, prompting immediate reporting to relevant authorities, including the Federal Bureau of Investigation and the Texas Department of Information Resources.

Despite concerted efforts to minimise the impact, TAD continues to work towards restoring full functionality to its services. Presently, while the TAD website remains accessible, the ability to search for records online has been temporarily suspended. Moreover, disruptions extend beyond the digital realm, with phone and email services also facing temporary outages. This development comes hot on the heels of a recent database failure experienced by TAD, which necessitated the expedited launch of a new website. Originally intending to run both old and new sites concurrently for a fortnight, the agency was compelled to hasten the transition following the database crash.

Chief Appraiser Joe Don Bobbitt has moved seamlessly to reassure the public, asserting that no sensitive information was compromised during the disruption. However, TAD remains vigilant and committed to addressing any lingering concerns. The agency is poised to provide further updates during an upcoming board meeting.

These recent challenges encountered by TAD underscore the critical importance of robust cybersecurity measures and organisational resilience in the face of unforeseen disruptions. Against the backdrop of escalating property values across North Texas, scrutiny of appraisal processes has intensified, with TAD having previously grappled with website functionality issues. Nevertheless, the agency remains steadfast in its commitment to enhancing user experience and fostering transparency.

In light of recent events, TAD remains resolute in prioritising the integrity of its operations and the safeguarding of sensitive data. The deliberate response to the ransomware attack prompts the agency's unwavering dedication to addressing emerging threats and maintaining public trust. As TAD diligently works towards restoring full operational capacity, stakeholders are urged to remain careful and report any suspicious activity promptly.

The resilience demonstrated by TAD in navigating these challenges serves as a testament to its dedication to serving the community and upholding the highest standards of accountability and transparency in property valuation processes.

Cyber Extortion Stoops Lowest: Fake Attacks, Whistleblowing, Cyber Extortion

Cyber Extortion

Recently, a car rental company in Europe fell victim to a fake cyberattack, the hacker used ChatGPT to make it look like the stolen data was legit. It makes us think why would threat actors claim a fabricated attack? We must know the workings of the cyber extortion business to understand why threat actors do what they do.

Mapping the Evolution of Cyber Extortion

Threats have been improving their ransomware attacks for years now. Traditional forms of ransomware attacks used encryption of stolen data. After successful encryption, attackers demanded ransom in exchange for a decryption key. This technique started to fail as businesses could retrieve data from backups.

To counter this, attackers made malware that compromised backups. Victims started paying, but FBI recommendations suggested they not pay.

The attackers soon realized they would need something foolproof to blackmail victims. They made ransomware that stole data without encryption. Even if victims had backups, attackers could still extort using stolen data, threatening to leak confidential data if the ransom wasn't paid.

Making matters even worse, attackers started "milking" the victims and further profiting from the stolen data. They started selling the stolen data to other threat actors who would launch repeated attacks (double and triple extortion attacks). Even if the victims' families and customers weren't safe, attackers would even go to the extent of blackmailing plastic surgery patients in clinics.

Extortion: Poking and Pressure Tactics

Regulators and law enforcement organizations cannot ignore this when billions of dollars are on the line. The State Department is offering a $10 million prize for the head of a Hive ransomware group, like to a scenario from a Wild West film. 

Businesses are required by regulatory bodies to disclose “all material” connected to cyber attacks. Certain regulations must be followed to avoid civil lawsuits, criminal prosecution, hefty fines and penalties, cease-and-desist orders, and the cancellation of securities registration.

Cyber-swatting is another strategy used by ransomware perpetrators to exert pressure. Extortionists have used swatting attacks to threaten hospitals, schools, members of the C-suite, and board members. Artificial intelligence (AI) systems are used to mimic voices and alert law enforcement to fictitious reports of a hostage crisis, bomb threat, or other grave accusation. EMS, fire, and police are called to the victim's house with heavy weapons.

What Businesses Can Do To Reduce The Risk Of Cyberattacks And Ransomware

What was once a straightforward phishing email has developed into a highly skilled cybercrime where extortionists use social engineering to steal data and conduct fraud, espionage, and infiltration. These are some recommended strategies that businesses can use to reduce risks.

1. Educate Staff: It's critical to have a continuous cybersecurity awareness program that informs staff members on the most recent attacks and extortion schemes used by criminals.

2. Pay Attention To The Causes Rather Than The Symptoms: Ransomware is a symptom, not the cause. Examine the methods by which ransomware infiltrated the system. Phishing, social engineering, unpatched software, and compromised credentials can all lead to ransomware.

3. Implement Security Training: Technology and cybersecurity tools by themselves are unable to combat social engineering, which modifies human nature. Employees can develop a security intuition by participating in hands-on training exercises and using phishing simulation platforms.

4. Use Phishing-Resistant MFA and a Password Manager: Require staff members to create lengthy, intricate passwords. To prevent password reuse, sign up for a paid password manager (not one built into your browser). Use MFA that is resistant to phishing attempts to lower the risk of corporate account takeovers and identity theft.

5. Ensure Employee Preparedness: Employees should be aware of the procedures to follow in the case of a cyberattack, as well as the roles and duties assigned to incident responders and other key players.

Aiohttp Cyble Internet Ransomware Vulnerabilities and Exploits

Critical Bug in aiohttp: Ransomware Attackers On A Roll

Critical Bug in aiohttp: Ransomware Attackers On A Roll

In the rapidly changing world of cybersecurity, cyber threats have been a nuisance and Ransomware is a constant menace. In a recent incident, cybersecurity firm Cyble found a serious vulnerability that threat actors are exploiting to get unauthenticated remote access to sensitive data from server files. Let's take a look into the concerning issue.

The Aiohttp Library Vulnerability

At the core of this story lies the Aiohttp Python library, a famous web synchronous framework that makes web apps and APIs. Sadly, a bug in the library has allowed hackers to break in. 

How does the vulnerability work?

The vulnerability, known as CVE-2024-23334 is a "directory traversal vulnerability." In other words, it lets unauthorized remote actors obtain files from a server they aren't ethically allowed to. 

This is how the vulnerability works:

1. Not enough Proper Validation: When setting routes for server files, Aiohttp is unable to execute proper validation. Particularly, the problem hits when the follow_symlinks option is set to true. 

2. Accessing files outside the Root Directory: Attackers exploit this flaw to traverse directories and steal files beyond the specified root directory. In simple terms, the attackers can steal sensitive information like databases, configuration files, and other important data. 

The flaw rates 7.5 on the CVSS scale. 

The Damage

The impact of the flaw is concerning:

1. Ransomware Attacks: Ransomware as a service (RaaS) attacks are monetizing on this flaw. Threat actors gain account critical files, encrypt them, and demand heavy randoms for decryption keys. 

2. Global Penetration: Cyble has found around 43,000 web-exposed Aiohttp incidents across the world. A lot of these servers are situated in the USA, Spain, Germany, and different Asian regions. 

3. Data Exposure: Companies using Aiohttp may cluelessly expose sensitive files on the internet. Threat actors can misuse this loophole and steal important data, disrupting user privacy and business operations. 

How to control it?

Follow these steps to protect your systems

1. Security Audits: Perform routine security audits of your web apps. Keep an eye out for incidents of Aiohttp and cross-check that they are using patched versions.

2. Access Controls: Have strict access controls. Restrict the Aiohttp accessible directories to avoid unauthorized traversal. 

3. Update Aiohttp: The Aiohttp development team immediately addressed the problem by releasing version 3.9.2. Make sure to update your Aiohttp installations as soon as possible. 

The ShadowSyndicate Links

Surprisingly, one of the IP addresses related to the hackers was earlier associated with the infamous ShadowSyndicate group. The group has a notorious history of foul play in ransomware attacks. This makes the exploitation of the Aiohttp flaw even more problematic. 

What can we learn?

The digital landscape is evolving, but so do cyber threats. The Aiohttp flaw is a sign that caution and routine updates are a must. We should stay informed, patch our systems timely, and strengthen defenses against ransomware attacks. 

Prevention is better than cure, a vigilant approach today will protect us from tomorrow's data hostility.

Aiohttp Ransomware Shadowssyndicate Threat Landscape Vulnerabilities and Exploits

Threat Actors Exploit the Aiohttp Bug to Locate Susceptible Networks

 

The ransomware actor "ShadowSyndicate" was observed searching for servers that could be exposed to the aiohttp Python library's directory traversal vulnerability, CVE-2024-23334. 

Aiohttp is an open-source toolkit designed to manage massively concurrent HTTP requests without the need for conventional thread-based networking. It is built on top of Python's Asyncio asynchronous I/O framework. 

Tech companies, web developers, data scientists, and backend engineers use it to create high-performance web applications and services that combine data gathered from numerous external APIs. 

On January 28, 2024, aiohttp published version 3.9.2, which addressed CVE-2024-23334, a high-severity path traversal issue that affects all versions of aiohttp from 3.9.1 and earlier and enables unauthenticated remote hackers to access files on susceptible servers. 

When 'follow_symlinks' is set to 'True' for static routes, there is insufficient validation, which leads to an unauthorised access to files located outside the server's static root directory On February 27, 2024, a researcher published a proof-of-concept (PoC) exploit for CVE-2024-23334 on GitHub, and a thorough video demonstrating step-by-step exploitation instructions was published on YouTube in early March.

Cyble's threat analysts indicate that their scanners detected exploitation attempts targeting CVE-2024-23334 beginning on February 29 and continuing at an increasing pace throughout March.

The scanning efforts originate from five IP addresses, one of which was identified in a Group-IB report from September 2023 as belonging to the Shadowsyndicate ransomware perpetrator. 

ShadowSyndicate is an opportunistic, financially motivated threat actor who has been active since July 2022 and has been associated to an array of ransomware variants, including Quantum, Nokoyawa, BlackCat/ALPHV, Clop, Royal, Cactus, and Play. Group-IB suspects the threat actor is an affiliate involved in numerous ransomware operations. 

Cyble's findings, while not conclusive, suggests that threat actors may be conducting scans on servers using a compromised version of the aiohttp library. Whether or whether these scans result in breaches is unknown at this moment. 

In terms of the attack surface, Cyble's internet scanner ODIN shows that there are around 44,170 internet-exposed aiohttp instances worldwide. The majority (15.8%) are in the United States, followed by Germany (8%), Spain (5.7%), the United Kingdom, Italy, France, Russia, and China.

International Initiative Targets Cybercrime

 


The Cybercrime Atlas initiative has shifted into its operational phase in 2024, marking a significant milestone in global cybersecurity efforts. Originating from discussions at the RSA Conference two years prior, the initiative aims to dismantle cybercriminal networks by mapping out their relationships, infrastructure, and supply chains.

Founded with the support of key players like Banco Santander, Fortinet, Microsoft, and Paypal, the initiative has since expanded to include over 20 law enforcement agencies, private-sector security firms, financial institutions, NGOs, and academic institutions. Together, they analyse intelligence packages and profile threat actors to disrupt cybercriminal operations effectively.

Derek Manky, Chief Security Strategist at Fortinet's FortiGuard Labs, emphasises the initiative's focus on intelligence gathering and the identification of choke points and disruption opportunities. The ultimate goal is to dismantle criminal infrastructure, make arrests, and reduce the profitability of cybercrime, sending a clear message to criminals.

Sean Doyle, the lead of the Cybercrime Atlas initiative, highlights its twofold purpose: creating actionable insights and using them collaboratively to impede cybercriminal activities. Despite recent high-profile cyber attacks, such as the ransomware attack on Change Healthcare and the British Library, the initiative strives to make life more challenging for cybercriminals.

The initiative's significance is underscored by the World Economic Forum's involvement and its recognition of cybersecurity as a critical global risk. With "cyber insecurity" ranked as the fourth top short-term global risk in the WEF's Global Risks Report 2024, the initiative represents a proactive approach to address digital threats.

Moreover, the WEF has actively engaged in addressing the cyber skills gap and promoting cybersecurity resilience among organisations. At its annual meeting in Davos, discussions on ransomware disruption garnered interest from CEOs and board members, reflecting a growing awareness of cybersecurity issues beyond traditional IT circles.

Tal Goldstein, Head of Strategy at the WEF Centre for Cybersecurity, emphasises the collaborative nature of tackling cyber threats, highlighting the need for concerted efforts from companies, governments, and international organisations. Recognising the complexity of cybersecurity challenges, the initiative signals a collective response to safeguarding digital ecosystems.

All in all, the Cybercrime Atlas initiative represents a pivotal step towards combating cybercrime on a global scale. With a focus on collaboration, intelligence gathering, and disruption tactics, it aims to mitigate the growing threat posed by cybercriminals, making cyberspace safer for individuals, businesses, and organisations worldwide.

Change Ransomware Attack: UnitedHealth Profits from a Crisis it Created

Change Ransomware Attack

Change Ransomware Incident: Details so far

The change Ransomware attack

  • Last week, an Oregon medical practice suffered a serious Ransomware attack called Change Ransomware.
  • Due to the attack, the medical practice was left with an empty bank account.
  • The only way out was to sell the practice to United Health. 

Emergency Exemption Request

  • UnitedHealth applied for an emergency exemption to speed up its acquisition of a medical practice in Corvallis, Oregon. 
  • The practice was on the verge of shutting down if the merger wasn't approved immediately.
  • The reason for this immediate merger is unclear, however, inside sources disclosed that it's the same issue affecting other health providers in the U.S.- the intentional weeks-long outage of United Health's Change Healthcare clearing and claims processing systems.
  • The outage compromised the flow of information essential for healthcare providers to get paid.

United Health's Profit Amid Crisis

  • United Health, a health insurer giant, has profited from desperation due to a hack of its Change computer systems. 
  • Roughly half of all healthcare transactions are down through Change.
  • The outage impacted 137 software apps that healthcare providers use. 
  • While healthcare providers try to cope with huge revenue losses, UnitedHealth keeps profiting and avoids disclosing its wealth.
  • UnitedHealth offered an emergency zero-interest lending program, providing small loans to healthcare institutions to "tide them over."

In the complicated healthcare industry, sometimes profit margins are prioritized over patient wellbeing. The recent UnitedHealth incident has raised concerns and left people in wonder. The controversy revolves around a Ransomware attack, a moral dilemma between ethical responsibility and financial interests, and an emergency exemption. UnitedHealth's Cyberattack Should Serve as a 'Wake-up Call' for HealthCare Sector

The Change Ransomware Attack

In Corvallis, Oregon, a medical facility practice faced a difficult situation. The change Ransomware attacks cost them their earnings, leaving the bank accounts empty, and almost pushing them on the verge of shutting down. 

To save themselves, the medical facility practice approached UnitedHealth. 

The Emergency Exemption Request

UnitedHealth immediately demanded an emergency exemption to speed the process of acquiring the struggling practice. The reason for the urgent exemption was unclear, however, inside sources suggested a common link: the weeks-long outage, that would slowly push healthcare providers on the brink of shutting down. The outage would disrupt the flow of information crucial for providing salaries to healthcare providers. 

UnitedHealth's Profits, Others Suffer in Crisis

Here's when the story gets interesting. UnitedHealth has profited from the desperate emergency exemption due to its own system's hacking. Half of the total healthcare transactions depend on Change. 

While healthcare providers were dealing with the losses and on the edge of falling, UnitedHealth declined to share its wealth. However, UnitedHealth is making profits. 

Learnings from the Change Ransomware Attack and UnitedHealth's Approach

The healthcare sector is also evolving quickly. Insurer Giants like UnitedHealth should be made accountable for their actions, and we must scrutinize their actions. 

The crisis amid which UnitedHealth made profits again underlines the dire need for accountability, transparency, and an honest commitment to patient wellbeing.

Ethics must prevail in the delicate balance between profit and well-being.

Cybersecurity Teams Tackle AI, Automation, and Cybercrime-as-a-Service Challenges

 




In the digital society, defenders are grappling with the transformative impact of artificial intelligence (AI), automation, and the rise of Cybercrime-as-a-Service. Recent research commissioned by Darktrace reveals that 89% of global IT security teams believe AI-augmented cyber threats will significantly impact their organisations within the next two years, yet 60% feel unprepared to defend against these evolving attacks.

One notable effect of AI in cybersecurity is its influence on phishing attempts. Darktrace's observations show a 135% increase in 'novel social engineering attacks' in early 2023, coinciding with the widespread adoption of ChatGPT2. These attacks, with linguistic deviations from typical phishing emails, indicate that generative AI is enabling threat actors to craft sophisticated and targeted attacks at an unprecedented speed and scale.

Moreover, the situation is further complicated by the rise of Cybercrime-as-a-Service. Darktrace's 2023 End of Year Threat Report highlights the dominance of cybercrime-as-a-service, with tools like malware-as-a-Service and ransomware-as-a-service making up the majority of harrowing tools used by attackers. This as-a-Service ecosystem provides attackers with pre-made malware, phishing email templates, payment processing systems, and even helplines, reducing the technical knowledge required to execute attacks.

As cyber threats become more automated and AI-augmented, the World Economic Forum's Global Cybersecurity Outlook 2024 warns that organisations maintaining minimum viable cyber resilience have decreased by 30% compared to 2023. Small and medium-sized companies, in particular, show a significant decline in cyber resilience. The need for proactive cyber readiness becomes pivotal in the face of an increasingly automated and AI-driven threat environment.

Traditionally, organisations relied on reactive measures, waiting for incidents to happen and using known attack data for threat detection and response. However, this approach is no longer sufficient. The shift to proactive cyber readiness involves identifying vulnerabilities, addressing security policy gaps, breaking down silos for comprehensive threat investigation, and leveraging AI to augment human analysts.

AI plays a crucial role in breaking down silos within Security Operations Centers (SOCs) by providing a proactive approach to scale up defenders. By correlating information from various systems, datasets, and tools, AI can offer real-time behavioural insights that human analysts alone cannot achieve. Darktrace's experience in applying AI to cybersecurity over the past decade emphasises the importance of a balanced mix of people, processes, and technology for effective cyber defence.

A successful human-AI partnership can alleviate the burden on security teams by automating time-intensive and error-prone tasks, allowing human analysts to focus on higher-value activities. This collaboration not only enhances incident response and continuous monitoring but also reduces burnout, supports data-driven decision-making, and addresses the skills shortage in cybersecurity.

As AI continues to advance, defenders must stay ahead, embracing a proactive approach to cyber resilience. Prioritising cybersecurity will not only protect institutions but also foster innovation and progress as AI development continues. The key takeaway is clear: the escalation in threats demands a collaborative effort between human expertise and AI capabilities to navigate the complex challenges posed by AI, automation, and Cybercrime-as-a-Service.

beer production Belgian brewery Cyber Attacks Cyberattack Cybersecurity Dark Web Duvel Moortgat IT department Ransomware Stormous

Ransomware Group Stormous Takes Responsibility for Cyberattack on Belgian Brewery

 

Stormous, a ransomware group, has admitted to orchestrating the cyber assault on Duvel Moortgat Brewery last Wednesday. Fortunately for beer enthusiasts, the brewery has ample stock to withstand the disruption.

The ransom group announced their involvement via the dark web on March 7th, a day following the attack, listing Duvel as their latest target. Despite this, there is no indication that the Belgian brewery intends to comply with any ransom demands, the specifics of which remain undisclosed. 

Duvel Moortgat has shown resilience in the face of adversity, as their IT department detected the ransomware attack in the early hours of March 6th, prompting an immediate halt in production.

Ellen Aarts, a spokesperson, confirmed the incident, stating that production ceased upon detection of the ransomware, with uncertainty about when it could resume. However, she assured that the brewery possesses sufficient beer inventory to manage the production halt.

Located in Breendonk, Antwerp, Duvel Moortgat is renowned for its signature Duvel ale, alongside Vedett and Maredsous beers, which enjoy international popularity.

Belgian beer enthusiasts took to Reddit to jest about the situation, showcasing their typical humour. Meanwhile, it was revealed that despite the disruption, beer pumps remained operational, leading some employees (excluding IT staff) to enjoy drinks in the cafeteria—a fact perhaps lamented by the IT department.

At present, the timeline for Duvel Moortgat to resume full-scale production remains uncertain, and the perpetrators behind the cyberattack remain unidentified.

United Health Allegedly Paid $22M Ransomware


Change Healthcare breach

There is evidence that the ransomware group behind the Change Healthcare breach, which has caused chaos for hospitals and pharmacies attempting to handle prescriptions, may have received $22 million from UnitedHealth Group.

Researchers studying security issues discovered a post made by an associate member claiming to be a member of the ALPHV/Blackcat ransomware group in a Russian forum used by cybercriminals. According to the member, Optum, a subsidiary of UnitedHealth Group, paid $22 million to obtain a decryption key and "prevent data leakage" to escape the continuous disruption at Change Healthcare, another UnitedHealth subsidiary.

After that, the forum post provides a link to a Bitcoin wallet that appears to have received 350 bitcoins. ALPHV, which mentions Recorded Future and TRM Labs as security companies, has also been linked to the same wallet.  

$22 Million ransom?

Ironically, the affiliate member divulged claims that they were duped out of that $22 million by the administrators of ALPHV. The affiliate member continues, saying, "Be careful everyone, and stop dealing with ALPHV." They claim to still have 4TB of Change Healthcare stolen data.  

A representative for UnitedHealth Group stated, "All I can share is that we remain focused on the investigation and recovery of our operations," in response to the alleged Bitcoin payment.

With no assurances that any of the stolen data will be erased, $22 million would rank among the largest ransomware payments if it turns out to be accurate. The current record holder is a $40 million payout made in 2021 by insurance behemoth CNA.

Additionally, the $22 million might give ransomware groups greater confidence to target the US health industry. For Change Healthcare, "connectivity issues" are still present on the platform two weeks after the ransomware outbreak started. Congressmen in the US were even moved by the disruption to request federal funding to cover the prescriptions' interim costs.

Why it is important?

The latest provider group to call for action in response to the disruption brought on by the cyberattack is the American Medical Association.

The American Medical Association has requested that the Biden administration provide emergency funding to doctors impacted by the outage.

The AMA wrote to Health and Human Services Secretary Xavier Becerra that physician practices have been forced to go without revenue for the twelfth day due to the cyber-takedown of Change Healthcare. 

The American Medical Association is pleading with Becerra to make use of all the powers at her disposal to guarantee the survival of medical practices and the provision of necessary treatment to patients.

The bigger picture

Speaking out about the interruptions to payments and operations brought about by Change's cybersecurity compromise, the AMA joins the AHA and MGMA in this regard.

This "is not even a band-bid on the payment problems," the American Hospital Association stated in a letter dated March 4 to Dirk McMahon, president, and chief operating officer of UnitedHealth Group, in response to the company's offer of Temporary Funding Assistance Program to resume hospital payment operations.

In a letter to the Department of Health and Human Services, MGMA requested enforcement discretion, financial resources, and direction to prevent what it described as a worsening of the negative effects on medical groups.

BlackCat Ransomware Hit Healthcare Giant Optum, Stolen 6TB Sensitive Data

 
In a shocking development, the notorious BlackCat/ALPHV ransomware gang has stepped forward to claim responsibility for a devastating cyberattack on Optum, a subsidiary of the healthcare giant UnitedHealth Group (UHG). This malicious breach has triggered an ongoing outage that is currently wreaking havoc on the Change Healthcare platform. 

BlackChat posted on their dark website that the group successfully exfiltrated a staggering 6 terabytes of data from Change Healthcare's network. This data includes information from lots of healthcare providers, insurance companies, and pharmacies. 

The stolen data has details about people's medical records, insurance, dental records, payments, and claims. It also has personal info like phone numbers, addresses, social security numbers, and email addresses for millions of people. The data even includes information about active U.S. military and navy personnel, making the situation even more serious. 

Change Healthcare serves as the primary payment exchange platform for a staggering network of over 70,000 pharmacies spread across the United States. The platform's critical role in facilitating transactions within the healthcare industry has been severely disrupted by the attack. 

UHG, the parent company of Optum, holds the distinction of being the largest healthcare conglomerate globally in terms of revenue. With a sprawling workforce of 440,000 employees worldwide, UHG collaborates with over 1.6 million physicians and healthcare professionals across a vast network of 8,000 hospitals and care facilities. 

Why BlackCat Ransomware Group Get So Much Attention From CY-Researchers? 

BlackCat ransomware, also known as ALPHV, has emerged as a notable threat in the realm of ransomware. What distinguishes BlackCat is its use of the Rust programming language, known for its emphasis on safety and performance. By leveraging Rust, BlackCat can evade detection by conventional security measures, presenting a formidable challenge for cybersecurity experts. 

Additionally, BlackCat showcases a high degree of sophistication by targeting a diverse array of devices and entry points. Its capability to compromise systems operating on Windows, Linux, and VMWare platforms highlights its adaptability and flexibility in executing attacks. Of particular concern is BlackCat's adoption of double extortion tactics. In addition to encrypting data, it exfiltrates sensitive information to exert pressure in ransom negotiations. 

Since its discovery in November 2021, BlackCat has remained a significant cybersecurity threat. Its ability to breach various systems serves as a stark reminder of the ever-evolving landscape of cyber threats, underscoring the importance of proactive defense strategies. 

Following the attack, Optum alerted users via a dedicated status page that the efforts were ongoing to restore affected systems to full functionality. They also emphasized that while their operations are being restored, systems belonging to Optum, UnitedHealthcare, and UnitedHealth Group remain unaffected by the cyberattack.

Cyber Crime Cybersecurity Law Enforcement LockBit ransomware group Ransomware

Law Enforcement Strikes Blow Against LockBit Ransomware Group

 



Marking a pivotal moment, the FBI and the U.K.'s National Crime Agency have scored a significant victory by gaining control of LockBit, a widely feared ransomware group. Their operation targeted LockBit's main website, the platform through which the group pressured victims into paying large ransom amounts. Instead of the original links leading to victims' data, authorities redirected users to press releases, sanctions details, and decryption information. This move marks a crucial step in the fight against cybercrime, as law enforcement takes bold actions to dismantle the operations of a prominent ransomware threat.

In a bold psychological manoeuvre, the law enforcement agencies hinted at having information about the leader of LockBit, known as "LockBitSupp." Although the reveal on Friday did not disclose the identity, authorities claimed to know who LockBitSupp is, where he resides, and his financial worth. Notably, they suggested that LockBitSupp has engaged with law enforcement, sparking intrigue about the nature of their interaction.

Experts suggest that this strategic messaging aims to undermine trust within the cybercrime community, particularly among LockBit's affiliates. By creating doubt and suspicion, law enforcement seeks to disrupt LockBit's operations and provoke a response from its leader. The approach appears tailored to the confident persona of LockBitSupp, who had previously offered a $10 million reward for anyone revealing his identity.

Cybersecurity analysts, including Jon DiMaggio of Analyst1, emphasize the psychological aspect of this operation, aiming to erode trust among cybercriminals and make them less likely to collaborate with LockBit. The strategy seems designed to target LockBitSupp's confidence and reputation.

Kurtis Minder, CEO of GroupSense and a ransomware negotiator, suggests that the messaging campaign might intentionally provoke LockBitSupp to say something incriminating. By insinuating collaboration between LockBitSupp and law enforcement, authorities seek to create distrust among affiliates who rely on LockBit's services.

Law enforcement's tactics also extend to the public relations realm, recognizing the need to win a battle against cybercriminals who have historically operated with impunity. By seizing the LockBit website and using it to disseminate information harmful to the criminal enterprise, authorities aim to turn cybercriminals' tools against them.

Allan Liska, a threat intelligence analyst at Recorded Future, highlights two possible interpretations of the police message about communication with law enforcement. It could suggest that LockBitSupp is an informant, a claim previously made by rival ransomware gangs. Alternatively, law enforcement might have infiltrated LockBitSupp's inner circle, with LockBitSupp unknowingly sharing sensitive information.

In the ongoing fight against online crime, law enforcement recognizes the importance of delivering impactful disruptions. By taking control of LockBit's infrastructure and using it to expose the group's activities, authorities aim to make their actions more marketable and showcase their effectiveness in combating cybercrime.

This event strongly implies a shift in law enforcement's approach, using strategic messaging and website seizures to not only disrupt criminal operations but also to sway public opinion and instil doubt within the cybercriminal community. The battle against ransomware continues, with authorities employing innovative tactics to bring cybercriminals to justice.

ConnectWise ScreenConnect Cyber Security Cybersecurity Mass Exploitation Ransomware remote desktop management Supply Chain Attack Vulnerability

Ransomware Distributed Through Mass Exploitation of ConnectWise ScreenConnect

 

Shortly after reports emerged regarding a significant security flaw in the ConnectWise ScreenConnect remote desktop management service, researchers are sounding the alarm about a potential large-scale supply chain attack.

Kyle Hanslovan, CEO of Huntress, expressed concerns about the exploitation of these vulnerabilities, warning that hackers could potentially infiltrate thousands of servers controlling numerous endpoints. He cautioned that this could lead to what might become the most significant cybersecurity incident of 2024. ScreenConnect's functionality, often used by tech support and others for remote authentication, poses a risk of unauthorized access to critical endpoints.

Compounding the issue is the widespread adoption of ScreenConnect by managed service providers (MSPs) to connect with customer environments. This mirrors previous incidents like the Kaseya attacks in 2021, where MSPs were exploited for broader access to downstream systems.

ConnectWise addressed the vulnerabilities without assigning CVEs initially, but subsequent proof-of-concept exploits emerged swiftly. By Tuesday, ConnectWise acknowledged active cyberattacks exploiting these bugs, and by Wednesday, multiple researchers reported increasing cyber activity.

The vulnerabilities now have designated CVEs, including a severe authentication bypass flaw (CVE-2024-1709) and a path traversal issue (CVE-2024-1708) enabling unauthorized file access.

The Shadowserver Foundation reported thousands of vulnerable instances exposed online, primarily in the US, with significant exploitation observed in the wild.

According to Huntress researchers, initial access brokers (IABs) are leveraging these bugs to gain access to various endpoints, intending to sell this access to ransomware groups. There have been instances of ransomware attacks targeting local governments, including endpoints potentially linked to critical systems like 911 services.

Bitdefender researchers corroborated these findings, noting the use of malicious extensions to deploy downloaders capable of installing additional malware.

The US Cybersecurity and Infrastructure Security Agency (CISA) added these vulnerabilities to its Known Exploited Vulnerabilities catalog.

Mitigation measures include applying patches released with ScreenConnect version 23.9.8 and monitoring for indicators of compromise (IoCs) as advised by ConnectWise. Additionally, organizations should vigilantly observe their systems for suspicious files and activities.

ConnectWise's actions to revoke licenses for unpatched servers offer some hope, although the severity of the situation remains a concern for anyone running vulnerable versions or failing to patch promptly.
