International Response to LockBit Ransomware
In a significant development, global authorities have disclosed the identity and initiated strict sanctions against Dmitry Yuryevich Khoroshev, a Russian national and the chief operator behind the LockBit ransomware. This move marks a pivotal moment in the ongoing battle against cybercrime. Khoroshev, known in cyber circles as ‘LockBitSupp’ and ‘putinkrab’, has been pinpointed as the mastermind responsible for orchestrating numerous cyberattacks, which purportedly amassed over $100 million in ransom payments. The coordinated efforts by the FBI, UK’s National Crime Agency, and Europol, alongside economic sanctions by the US Department of the Treasury and similar bodies in the UK and Australia, aim to dismantle the operations of the LockBit group. These sanctions include travel bans and asset freezes, emphasizing the seriousness of the international stance against cyber threats. The collective actions not only highlight the capacity of international law enforcement to track and penalize cybercriminals but also serve as a deterrent to similar criminal endeavors.
Data Breach Exposes UK Ministry of Defence Payroll Information
The UK Ministry of Defence (MoD) has been compromised in a data breach, leading to unauthorized access to a significant portion of the Armed Forces payroll data. This breach impacted personal details including names, bank account information, and, in some instances, addresses of active, reserve, and some retired military personnel. The total number of affected payroll records is estimated at 270,000. Defence Secretary Grant Shapps, addressing the House of Commons, confirmed that an external contractor’s system, distinct from the MoD’s primary networks, was the point of intrusion. This system has been isolated to prevent further exposure, and while the breach did not disrupt the issuance of April salaries and other payments, it raised serious concerns about data security. An ongoing investigation suggests potential security lapses by the contractor might have facilitated the breach. The affected individuals are being notified, and while no data theft has been confirmed, the possibility of foreign state involvement is being considered.
Exploitation of LiteSpeed Cache Vulnerability in WordPress Sites
Cybercriminals are exploiting a severe vulnerability in the LiteSpeed Cache plugin to unauthorizedly create admin accounts on WordPress websites. This plugin, which enhances site performance and is used by over five million sites, has a critical flaw in versions earlier than 5.7.0.1. Identified as CVE-2023-40000, this vulnerability allows attackers to inject malicious JavaScript, leading to the creation of administrator profiles with potentially harmful intentions. According to WPScan, this flaw has been actively exploited since April, with attackers deploying code that targets WordPress files and databases to establish control over sites.
This issue is compounded by another targeted attack on the WordPress plugin “Email Subscribers,” exploiting a different SQL injection flaw, CVE-2024-2876, which allows the creation of admin accounts via unauthorized database queries. Despite the lesser popularity of this plugin, the impact remains significant.
Website administrators are urged to update their plugins to the latest versions promptly, deactivate unnecessary components, and closely monitor for the creation of new admin accounts. In instances of confirmed breaches, a comprehensive site cleanup, including the removal of all unauthorized accounts and restoration from clean backups, is essential to secure the sites from further exploitation.
DocGo Announces Data Breach Involving Patient Health Information
DocGo, a mobile healthcare provider operating across thirty U.S. states and the United Kingdom, has disclosed a significant cyberattack resulting in the theft of patient health data. The breach, confirmed through a recent SEC Form 8-K filing, highlighted that unauthorized access was detected in their systems, prompting an immediate response to mitigate the incident. The company swiftly initiated containment measures and launched a comprehensive investigation with the aid of third-party cybersecurity experts. This breach specifically impacted a limited number of health records from their U.S.-based ambulance services.
Despite the sensitive nature of the stolen data, DocGo has reassured that the breach was contained to a single business unit and that there is no indication of ongoing unauthorized activities. They are currently notifying affected individuals and have reported the incident to law enforcement. Although no ransomware group has yet claimed responsibility for the attack, the potential for the misuse of the stolen data could pose future challenges. DocGo remains confident, however, that this incident will not materially impact their overall operations or financial stability.
Monday.com Disables Feature After Phishing Exploit
Monday.com, a widely used project management platform, has decided to remove its “Share Update” feature following its exploitation in phishing attacks. The feature, intended to enhance communication by allowing updates to be shared with non-account members, was misused by threat actors to send phishing emails. These deceptive messages, which appeared to be from the “Human Resources” department, directed recipients to phishing sites via shortened URLs.
The phishing activity was first flagged by concerned Monday.com customers who reported unusual emails purportedly sent from the platform’s official accounts. The emails passed all standard authentication checks, including SPF, DMARC, and DKIM, making them appear legitimate. Upon investigation, it was revealed that the attacks were facilitated through the “Share Update” feature, prompting Monday.com to immediately disable the feature and suspend the offending user.
The company has since contacted all recipients of the phishing emails to alert them to the security risk. While the feature was not linked to any data hosted on Monday.com or any customer account access, its misuse led to its removal to prevent further abuse. Monday.com is currently reviewing the feature and has not specified if or when it might be reinstated.
Google Patches Critical Zero-Day in Chrome
Google has swiftly addressed the fifth zero-day vulnerability found in Chrome this year, rolling out a security update to mitigate the issue. Identified as CVE-2024-4671, this high-severity vulnerability exists in the Visuals component of Chrome, which is responsible for rendering and displaying content. The flaw, a “use after free” issue, can lead to data leakage, arbitrary code execution, or crashes when the freed memory is accessed by the program after its release.
The vulnerability was discovered and reported by an anonymous researcher and had been actively exploited in the wild. Google has not disclosed specific details about the attacks but has confirmed their occurrence. The tech giant has released version 124.0.6367.201/.202 for Windows and Mac, and 124.0.6367.201 for Linux, with updates scheduled to roll out gradually.
Users are encouraged to verify that their Chrome browser is updated to the latest version by checking in Settings > About Chrome. This proactive measure ensures the application of critical security updates, safeguarding users against potential exploits. This incident underscores the importance of maintaining current software versions and highlights Google’s ongoing efforts to secure user data against evolving cyber threats.
Ascension Healthcare System Hit by Suspected Ransomware Attack
Ascension, a prominent U.S. healthcare network, is currently facing significant operational disruptions due to a suspected ransomware attack, leading to the diversion of ambulance services to alternative hospitals. The attack, which began affecting systems on Wednesday, has forced the shutdown of critical platforms including the MyChart electronic health records system, along with various communication and medical ordering systems.
In response to the crisis, Ascension has implemented “downtime procedures,” prompting several hospitals within its network to divert emergency services to ensure prompt medical triage. This measure is part of a broader strategy to manage the impact while the organization works towards restoring full functionality to its systems. Elective procedures and non-emergency appointments have been temporarily paused, with the healthcare provider urging affected patients to bring detailed personal medical information to any rescheduled appointments.
The incident is under investigation with the help of Mandiant cybersecurity experts, and while the specific perpetrators have not been officially confirmed, sources indicate that the Black Basta ransomware group may be responsible. This group has been actively targeting the healthcare sector and is known for its damaging ransomware campaigns. Ascension is taking extensive measures to mitigate the effects of the attack and has advised business partners to sever connections with its network as a precaution.
