Command Injection Attacks Cyber Security Data Rust vulnerability Safety Windows security flaw

Windows Systems Vulnerable to Attacks Due to Critical 'BatBadBut' Rust Flaw

 

A significant security loophole within the Rust standard library has emerged, posing a threat specifically to Windows users by enabling potential command injection attacks. Designated as CVE-2024-24576 and carrying a maximum severity score of 10.0 according to the Common Vulnerability Scoring System (CVSS), this vulnerability is significant. However, it's worth noting that it solely affects situations where batch files are called upon in Windows environments with untrusted arguments.

The Rust Security Response working group, in an advisory issued on April 9, 2024, highlighted that the flaw arises from inadequacies in the Rust standard library's handling of arguments when initiating batch files (bearing the .bat and .cmd extensions) on Windows via the Command API. Essentially, the flaw permits attackers to execute arbitrary shell commands by circumventing the established escaping mechanisms.

This vulnerability affects all Rust versions preceding 1.77.2 and was initially discovered and reported by security researcher RyotaK to the CERT Coordination Center (CERT/CC). RyotaK, who named the vulnerability "BatBadBut," emphasized that it impacts multiple programming languages and stems from the manner in which these languages utilize the CreateProcess function in Windows while incorporating escape mechanisms for command arguments.

According to CERT/CC, the vulnerability underscores a broader issue wherein programming languages lack robust validation mechanisms for executing commands within the Windows environment. This oversight potentially allows attackers to execute disguised arbitrary code as command arguments.

The extent of the vulnerability's impact hinges on the implementation of vulnerable programming languages or modules. As not all programming languages have rectified the issue, developers are advised to exercise caution when executing commands on Windows platforms.

In order to mitigate the risk of inadvertent execution of batch files, RyotaK recommends relocating such files to a directory not included in the PATH environment variable. By doing so, batch files would only execute upon specification of their full path, thereby reducing the likelihood of unexpected execution.

Gmail malware MFA Bypass Microsoft 365 multifactor authentication phishing kit Safety Security Tycoon

'Tycoon' Malware Kit Bypasses Microsoft and Google Multifactor Authentication

 

An emerging phishing kit called "Tycoon 2FA" is gaining widespread use among threat actors, who are employing it to target Microsoft 365 and Gmail email accounts. This kit, discovered by researchers at Sekoia, has been active since at least August and received updates as recent as last month to enhance its evasion techniques against multifactor authentication (MFA).

According to the researchers, Tycoon 2FA is extensively utilized in various phishing campaigns, primarily aimed at harvesting Microsoft 365 session cookies to bypass MFA processes during subsequent logins. The platform has amassed over 1,100 domain names between October 2023 and late February, with distribution facilitated through Telegram channels under different handles such as Tycoon Group, SaaadFridi, and Mr_XaaD.

Operating as a phishing-as-a-service (PhaaS) platform, Tycoon 2FA offers ready-made phishing pages for Microsoft 365 and Gmail accounts, along with attachment templates, starting at $120 for 10 days, with prices varying based on the domain extension. Transactions are conducted via Bitcoin wallets managed by the "Saad Tycoon Group," suspected to be the operator and developer of Tycoon 2FA, with over 1,800 recorded transactions as of mid-March.

The phishing technique employed by Tycoon 2FA involves an adversary-in-the-middle (AitM) approach, utilizing a reverse proxy server to host phishing webpages. This method intercepts user inputs, including MFA tokens, allowing attackers to bypass MFA even if credentials are changed between sessions.

Despite the security enhancements provided by MFA, sophisticated attacks like Tycoon 2FA pose significant threats by exploiting AitM techniques. The ease of use and relatively low cost of Tycoon 2FA make it appealing to threat actors, further compounded by its stealth capabilities that evade detection by security products.

Sekoia researchers outlined a six-stage process used by Tycoon 2FA to execute phishing attacks, including URL redirections, Cloudflare Turnstile challenges, JavaScript execution, and the presentation of fake authentication pages to victims.

The emergence of Tycoon 2FA underscores the evolving landscape of phishing attacks, challenging the effectiveness of traditional MFA methods. However, security experts suggest that certain forms of MFA, such as security keys implementing WebAuthn/FIDO2 standards, offer higher resistance against phishing attempts.

To assist organizations in identifying Tycoon 2FA activities, Sekoia has published a list of indicators of compromise (IoCs) on GitHub, including URLs associated with Tycoon 2FA phishing campaigns.

Researchers Unveil Sound-Based Attack: Swipe Sounds Used to Recreate Fingerprints

 

A group of researchers from China and the US has introduced an intriguing new method for compromising biometric security systems. Their study, titled "PrintListener: Uncovering the Vulnerability of Fingerprint Authentication via the Finger Friction Sound," presents a novel side-channel attack aimed at the sophisticated Automatic Fingerprint Identification System (AFIS). 

This attack exploits the sound produced by a user's finger swiping across a touchscreen to extract fingerprint pattern details. Through testing, the researchers claim success rates of attacking "up to 27.9% of partial fingerprints and 9.3% of complete fingerprints within five attempts at the highest security FAR [False Acceptance Rate] setting of 0.01%." This research marks the first instance of utilizing swiping sounds to deduce fingerprint information.

Fingerprint biometric security measures are prevalent and widely trusted, with projections suggesting the fingerprint authentication market could reach nearly $100 billion by 2032. However, with growing awareness of potential fingerprint theft, individuals and organizations are becoming more cautious about exposing their fingerprints, even in photographs.

In the absence of direct access to fingerprints or detailed finger images, attackers have found a new avenue for obtaining fingerprint data to bolster dictionary attacks like MasterPrint and DeepMasterPrint. The PrintListener study reveals that "finger-swiping friction sounds can be captured by attackers online with a high possibility," using common communication apps such as Discord, Skype, WeChat, and FaceTime. By exploiting these sounds, the researchers developed PrintListener, a sophisticated attack method.

PrintListener overcomes significant challenges, including capturing faint friction sounds, separating fingerprint influences from other user characteristics, and advancing from primary to secondary fingerprint features. The researchers achieved this through the development of algorithms for sound localization, feature extraction, and statistical analysis.

Through extensive real-world experiments, PrintListener demonstrates remarkable success rates in compromising fingerprint security, surpassing unassisted dictionary attacks. This research underscores the importance of addressing emerging threats to biometric authentication systems and developing robust countermeasures to safeguard sensitive data.

Here's How to Safeguard Your Online Travel Accounts from Hackers

 

Just days following Kay Pedersen's hotel reservation in Chiang Mai, Thailand, via Booking.com, she received a troubling email. The email, poorly written in broken English, warned her of "malicious activities" within her account.

Subsequently, Kay and her husband, Steven, encountered issues. Steven noticed unauthorized reservations at different hotels, prompting them to report the fraudulent activity to Booking.com. In response, Booking.com cancelled all their bookings, including the one in Chiang Mai. Despite their immediate action, restoring their original reservation proved challenging. While Booking.com eventually reinstated the reservation, the new rate was more than double the original.

The Pedersens are not isolated cases. A recent surge in hacking incidents has targeted travellers. Criminals reportedly obtained Booking.com passwords through its internal messaging system. Loyalty program accounts and other online travel agencies have also been popular targets.

The susceptibility of travel accounts to attacks is attributed to the wealth of sensitive information they hold, including passports, driver’s licenses, and travel dates. Caroline McCaffery, CEO of ClearOPS, underscores the importance of safeguarding this information.

To mitigate the risk of hacking, travellers can employ several strategies:

1. Utilize two-factor authentication, preferably through an authenticator app, to enhance security.
2. Enable login notifications to receive alerts of any unauthorized account access.
3. Avoid reusing passwords and opt for strong, unique passwords for each account. Password management services like Google Password Manager can be helpful.
4. Exercise caution when using public Wi-Fi networks, and employ a Virtual Private Network (VPN) for added security.

However, travellers themselves also contribute to the problem by sharing excessive personal information and falling victim to phishing scams. Bob Bacheler, managing director of Flying Angels, highlights the risks associated with oversharing on social media and with unknown websites.

Phishing, in particular, remains a prevalent method for hacking attempts. Albert Martinek, a customer cyber threat intelligence analyst at Horizon3.ai, emphasizes the dangers of clicking on suspicious links.

The Pedersens' case underscores the challenges travellers face in resolving hacking incidents. While Booking.com investigated and secured their account, the couple endured uncertainty regarding their hotel reservation.

Ultimately, responsibility for addressing these security concerns lies with the companies that handle travellers' data. Implementing passwordless authentication systems like Passkeys could offer a solution to mitigate hacking risks. However, until travel companies prioritize safeguarding personal information, travellers will continue to bear the consequences.

Multiple Iterations of 'HeadCrab' Malware Seize Control of Numerous Servers

 

The HeadCrab malware, known for incorporating infected devices into a botnet for various cyber activities, has reappeared with a novel variant that grants root access to Redis open source servers.

According to findings by Aqua Security researchers, the second version of this cryptomining malware has impacted 1,100 servers, with the initial variant having already compromised a minimum of 1,200 servers.

Asaf Eitani, a security researcher from Team Nautilus, Aqua Security's research team, clarified that while HeadCrab doesn't conform to the typical rootkit, its creator has endowed it with the capability to manipulate a function and generate responses. In essence, this mirrors rootkit behavior as it gains control over responses, allowing it to modify and remain undetected.

Eitani explained, "The tradition of the term rootkit is malware that has root access and controls everything, but in this sense, you are able to control what the user sees."

The updated variant includes subtle adjustments enabling attackers to better conceal their activities. Custom commands have been removed, and encryption has been integrated into the command and control infrastructure, enhancing stealth.

A distinctive feature of HeadCrab is a "mini blog" within the malware, where the author, operating under the pseudonym Ice9, provides technical details about the malware and leaves a Proton Mail email address for anonymity. 

While Aqua Security researchers contacted Ice9, they were unable to ascertain his identity or location. Ice9 claimed they were the first to reach out and insisted that the malware doesn't impair server performance, asserting its ability to eliminate other malware infections. Ice9 praised the researchers in the mini blog after they discovered the second variant.

Notably, Ice9 is the sole user of HeadCrab and exclusively manages the command and control infrastructure.

HeadCrab infiltrates a Redis server when an attacker utilizes the SLAVEOF command, downloads a malicious module, and executes two new files—a cryptominer and a configuration file. Aqua Security researchers advise organizations to conduct scans for vulnerabilities and misconfigurations in their servers and implement protected mode in Redis to minimize the risk of HeadCrab infection.

Record Surge in Data Breaches Fueled by Ransomware and Vendor Exploits

 

According to a recent report from Apple and a Massachusetts Institute of Technology researcher, the United States has witnessed a record-breaking surge in data breaches, fueled by increased attacks on third-party vendors and a rise in aggressive ransomware incidents. 

The study, authored by MIT professor Stuart Madnick and released on Thursday, reveals a distressing trend, with data breaches more than tripling from 2013 to 2022 and compromising a staggering 2.6 billion personal records in the past two years alone.

The situation has further escalated in 2023, with the first eight months seeing over 360 million individuals affected by corporate and institutional data breaches. Alarmingly, one in four Americans had their health data exposed in these breaches during this period. The report also highlights an increase in ransomware attacks, surpassing the total for the entire year of 2022. In the first three quarters of 2023, ransomware attacks rose by nearly 70% compared to the same period in the previous year.

A survey conducted in 2023 among 233 IT and cybersecurity professionals in the healthcare sector across 14 countries revealed that 60% of organizations in the sector faced ransomware attacks, almost double the reported rate in 2021. The largest health data breach this year involved an email hacking incident reported by HCA Healthcare, affecting 11 million individuals.

Data breaches have not been limited to the healthcare sector, as millions of individuals across various economic sectors have been impacted. Third-party vendor incidents have been particularly prominent, with exploits targeting vulnerabilities in Progress Software's MOVEit and Fortra's GoAnywhere file transfer applications.

The report emphasizes the widespread consequences of vendor exploitation attacks, where initial breaches provide hackers access not only to the vendor's system and data but also to the systems and data of the vendor's clients. The study notes that approximately 98% of organizations reported having a relationship with a vendor that experienced a data breach within the last two years.

In light of these findings, the report underscores the urgent need for organizations to prioritize the security of personal data, given the prevalence of data breaches and their tangible consequences for individuals.

This shift in dynamics is evident in the ongoing legal battle between Google and Epic Games, where Epic Games accuses Google of stifling competition by imposing high fees on app developers.

Google CEO Sundar Pichai has defended Google's stance, citing security concerns associated with sideloading apps. He emphasizes that Google's policies, exemplified by Android's diverse device designs, foster innovation and provide users with choices.

However, Pichai's emphasis on security raises eyebrows, as Android has always been known for its open-source nature and embrace of sideloading. His focus on potential malware infections seems to be a tactic to instill fear among users. In reality, Google's Play Protect feature is only a recent addition for screening sideloaded apps.

Critics argue that sideloading empowers Google with greater control over the apps users can access. While Google maintains that the Play Store provides the highest level of security, a study by Kaspersky Labs contradicts this claim, revealing that over 600 million malicious app downloads occurred from the Google Play Store in 2023 alone.

Apple's staunch opposition to sideloading stems from its desire to retain control over the app distribution process on iPhones. However, both Apple and Google are undoubtedly aware of the 30% commission they charge developers for hosting apps on their respective app stores. This hefty fee has driven companies like Epic Games to explore alternative distribution channels.

The debate over sideloading highlights the growing tension between app developers, app store operators, and users. As the battle for app distribution intensifies, it remains to be seen whether sideloading will become a mainstream practice or remain a niche alternative.

AI/ML Tools Uncovered with 12+ Vulnerabilities Open to Exploitation

 

Since August 2023, individuals on the Huntr bug bounty platform dedicated to artificial intelligence (AI) and machine learning (ML) have exposed more than a dozen vulnerabilities that jeopardize AI/ML models, leading to potential system takeovers and theft of sensitive information.

Discovered in widely used tools, including H2O-3, MLflow, and Ray, each boasting hundreds of thousands or even millions of monthly downloads, these vulnerabilities have broader implications for the entire AI/ML supply chain, according to Protect AI, the entity overseeing Huntr.

H2O-3, a low-code machine learning platform facilitating the creation and deployment of ML models through a user-friendly web interface, has been revealed to have default network exposure without authentication. This flaw allows attackers to provide malicious Java objects, executed by H2O-3, providing unauthorized access to the operating system.

One significant vulnerability identified in H2O-3, labeled as CVE-2023-6016 with a CVSS score of 10, enables remote code execution (RCE), allowing attackers to seize control of the server and pilfer models, credentials, and other data. Bug hunters also pinpointed a local file include flaw (CVE-2023-6038), a cross-site scripting (XSS) bug (CVE-2023-6013), and a high-severity S3 bucket takeover vulnerability (CVE-2023-6017).

Moving on to MLflow, an open-source platform managing the entire ML lifecycle, it was disclosed that it lacks default authentication. Researchers identified four critical vulnerabilities, with the most severe being arbitrary file write and patch traversal bugs (CVE-2023-6018 and CVE-2023-6015, CVSS score of 10). These bugs empower unauthenticated attackers to overwrite files on the operating system and achieve RCE. Additionally, critical-severity arbitrary file inclusion (CVE-2023-1177) and authentication bypass (CVE-2023-6014) vulnerabilities were discovered.

The Ray project, an open-source framework for distributed ML model training, shares a similar default authentication vulnerability. A crucial code injection flaw in Ray's cpu_profile format parameter (CVE-2023-6019, CVSS score of 10) could result in a complete system compromise. The parameter lacked validation before being inserted into a system command executed in a shell. Bug hunters also identified two critical local file include issues (CVE-2023-6020 and CVE-2023-6021), enabling remote attackers to read any files on the Ray system.

All these vulnerabilities were responsibly reported to the respective vendors at least 45 days before public disclosure. Users are strongly advised to update their installations to the latest non-vulnerable versions and restrict access to applications lacking available patches.

British Library Hit by Cyber Incident, Disrupting Services

 

The British Library in London, known for its serene study environment and vast collection of 170 million items, has been disrupted by a "cyber incident." This event has led to the shutdown of its website, impeding access to the online catalog, and the cessation of Wi-Fi services. 

Staff members are unable to use computers, creating a predigital atmosphere within the library. Ordering books now involves consulting hardback catalogs or external websites, writing down catalog numbers, and handing them to librarians for verification. The incident has affected various users, including authors and academics, who rely on the library for their work.

Despite the significance of the British Library, the institution has provided minimal information about the incident on social media. The library stated that it is facing a major technology outage due to the cyber incident, impacting both online and on-site services. 

The staff is collaborating with Britain's National Cyber Security Center to investigate the matter. Speculation about the cause of the shutdown abounds among users, with many having to adjust their work plans to accommodate the disruption.

While details remain scarce, other European libraries presume the British Library was deliberately targeted. The National Library of Scotland, for instance, has intensified its monitoring and protection in response to the attack. 

This incident underscores a shift in cybercriminals targeting libraries, which traditionally flew under the radar. Tasmina Islam, a cybersecurity education lecturer, suggests that financial motives may be driving such attacks, as libraries house valuable information, including personal data and intellectual property. She emphasizes the need for libraries and institutions to enhance their security measures.

Within the British Library, employees are puzzled by the event, describing it as a "nightmare." However, not all users are dismayed by the interruption. Eric Langley, a Shakespeare scholar, finds the blackout oddly liberating, allowing him to focus solely on the bard's work. Nevertheless, he acknowledges that an extended disruption would pose challenges.

Notorious Ransomware Gang Claims Responsibility for Cyberattack on Southwestern Ontario Hospitals

 

A notorious cybercrime gang known as Daixin Team has publicly admitted to pilfering millions of records from five hospitals in southern Ontario, subsequently leaking the data online when their ransom demands were not met. The targeted hospitals include those in Leamington, Windsor, Sarnia, and Chatham-Kent. The Windsor Star has obtained a purported link to the leaked information, which is hosted on the dark web, offering access to personal details of patients from these facilities.

While the hospitals confirmed the publication of the compromised data, they did not officially confirm Daixin Team's involvement. Windsor Regional Hospital CEO, David Musyj, emphasized that the attackers were part of a sophisticated and organized operation, rather than an isolated individual. 

The affected hospitals, including Sarnia’s Bluewater Health, Chatham-Kent Health Alliance, Windsor-Essex hospice, Erie Shores HealthCare, Hôtel-Dieu Grace Healthcare, and Windsor Regional Hospital, continue to grapple with system access issues following the cyberattack on October 23. In addition to disrupting digital and tech-based systems, the perpetrators made off with substantial amounts of personal information pertaining to both staff and patients. When the hospitals refused to yield to ransom demands, the criminals opted to disseminate the pilfered data.

A comprehensive investigation, involving local police departments, the Ontario Provincial Police, the FBI, and INTERPOL, is underway. Daixin Team has a track record of similar cyberattacks against various organizations, including a German water metering company, AirAsia, Fitzbiggon Hospital in Missouri, and OakBend Medical Centre in Texas.

Brett Callow, a threat analyst at the cybersecurity firm Emsisoft Ltd., emphasized that Daixin Team has been active since the middle of the previous year and has repeatedly targeted healthcare organizations. He cautioned that while this incident is unfortunate, it may not be the last, and underscored the urgency for robust cybersecurity measures in the healthcare sector. Following the breach, the hackers locked the hospitals out of their own systems by targeting TransForm Shared Service Organization, which oversees technology systems for all five facilities.

Musyj revealed that the extent of the stolen data is still unknown, but investigations are ongoing. He emphasized that the decision not to pay the ransom aligns with the joint statement from the 50 members of the International Counter Ransomware Initiative, which includes Canada. Callow, however, stressed that global governments need to take more effective measures to combat cybercriminals.

The U.S. government’s Cybersecurity and Infrastructure Security Agency issued a warning about Daixin Team last year, specifying that the group targets businesses in the Healthcare and Public Health sector with ransomware and data extortion operations. They encrypt servers responsible for healthcare, exfiltrate personal information, and demand ransom payments.

Callow concluded by advising caution and preparation for potential misuse of the compromised information, given the hackers' track record. He recommended assuming that the information could be exploited and taking appropriate precautions.
