A hacking group called Void Arachne is targeting Chinese-speaking users with a malware campaign disguised as legitimate software installers. The malware steals user data, grants remote access to attackers, and avoids detection by targeting specific antivirus software. Users should be cautious when downloading software and only download from trusted sources.
A new and sophisticated phishing-as-a-service (PhaaS) platform, dubbed ONNX Store, has emerged, targeting Microsoft 365 accounts within financial institutions through a novel approach involving QR codes embedded in PDF attachments. This platform represents a notable evolution in phishing tactics, leveraging the guise of legitimate communication channels to infiltrate corporate networks and compromise sensitive data. ONNX Store's operational framework bears striking resemblance to the previously identified Caffeine phishing kit, attributed to the Arabic-speaking threat actor MRxC0DER, indicating a potentially orchestrated campaign with wide-ranging implications.
Cybercriminals distribute malware disguised as popular software, luring users into downloading Trojanized applications. The hidden malware loader launches Vidar Stealer, stealing browser passwords and deploying additional malicious payloads. Caution when downloading software and avoiding suspicious emails is crucial to thwart such attacks.
Two vulnerabilities in Mailcow's open-source mail server suite, CVE-2024-30270 and CVE-2024-31204, could allow malicious actors to execute arbitrary code. The flaws, affecting versions before 2024-04, were disclosed by SonarSource and involve path traversal and cross-site scripting. Exploiting these vulnerabilities could enable attackers to hijack admin sessions and execute commands on the server.
Insikt Group observed a malicious campaign using Vortax, a fake virtual meeting app, to target cryptocurrency users. Vortax, posing as a legitimate software, delivers three infostealers, including the rare macOS-targeting AMOS, to steal sensitive information. The campaign, likely run by the threat actor "markopolo," represents a significant threat to both Windows and macOS users.
AMD is investigating a potential data breach after the hacker group IntelBroker claimed to have stolen company databases. The stolen data allegedly includes information on future AMD products, spec sheets, and databases covering employee and customer information. To substantiate their claims, IntelBroker posted screenshots showing corporate email addresses and internal phone numbers of AMD employees. However, the employee information appears outdated, and no customer data has been posted yet. IntelBroker is seeking to sell the stolen data for cryptocurrency and has a history of selling data from other high-profile breaches.
Maxicare has reported a security breach involving unauthorized access to personal information. The incident affects about 13,000 members, less than 1% of Maxicare’s total membership, and pertains to booking requests through Lab@Home, a third-party provider. Maxicare assures no sensitive medical data was exposed and that their main systems remain unaffected.

The International Monetary Fund (IMF) recommends governments impose a green tax on AI-related carbon emissions and excess profits to address environmental and economic impacts. Generative AI's rapid development and high energy consumption are projected to significantly increase carbon emissions from data centers. The IMF suggests alternative taxation on capital income and excess profits to mitigate job losses and wealth inequality caused by AI automation.
Microsoft has published a white paper detailing its double key encryption methods for securing customer data, following pressure from Germany's Federal Office for Information Security (BSI). The disclosure comes after BSI invoked a legal clause demanding comprehensive information on Microsoft's encryption practices. This move is part of BSI's ongoing investigation into security measures following a 2023 hack attributed to a Chinese threat actor, raising concerns about Microsoft's security protocols.
The United States and Indonesia conducted their first port-focused cybersecurity exercise in Surabaya, aiming to enhance maritime cyber resilience against potential attacks.
