Cybersecurity researchers Tal Peleg and Coby Abrams from Varonis have identified a significant security vulnerability in PostgreSQL, designated as CVE-2024-10979, which has a CVSS severity score of 8.8. This vulnerability affects all PostgreSQL versions prior to 17.1, 16.5, 15.9, 14.14, 13.17, and 12.21. It allows unprivileged users to manipulate environment variables within the PostgreSQL PL/Perl extension, potentially enabling arbitrary code execution. PostgreSQL's advisory states that this flaw can lead to data theft or system takeover by altering sensitive process environment variables. Users are advised to update to the fixed versions and implement restrictions on allowed extensions and user permissions to mitigate the risk.

A new Android malware named "ToxicPanda" was first identified in late October 2024 and has been reclassified as a unique entity after initial classification under the TgToxic family. It poses a risk through account takeover via on-device fraud and primarily targets retail banking applications on Android devices. The malware has spread significantly in Italy, Portugal, Spain, and various Latin American regions, with over 1,500 devices reported as victims. ToxicPanda allows cybercriminals to gain remote access to infected devices, intercept one-time passwords, and bypass two-factor authentication. The threat actors are likely Chinese speakers, which is unusual for targeting European banking. The malware spreads through social engineering tactics, encouraging users to side-load the malicious app, and exploits Android’s accessibility services for elevated permissions. Cleafy’s analysis indicates that ToxicPanda's command-and-control infrastructure shows evolving operational strategies, and the malware may undergo further modifications. The challenges for security professionals are increasing as malware operators refine their tactics and expand their targets. Cleafy noted that contemporary antivirus solutions have struggled to detect ToxicPanda due to a lack of proactive, real-time detection systems.

Cybersecurity experts from Dr.Web have discovered a cyber attack involving Trojan.AutoIt.1443, targeting approximately 28,000 users primarily in Russia and neighboring countries. The malware disguises itself as legitimate applications and is spread through deceptive links on platforms like GitHub and YouTube, leading to password-protected downloads that evade antivirus detection. Key components of the malware include UnRar.exe and scripts named Iun.bat and Uun.bat, which facilitate its installation while erasing traces of activity. The malware scans for debugging tools, establishes network access via Ncat, and manipulates the system registry to maintain persistence. Its operations include cryptomining using SilentCryptoMiner and cryptostealing through a clipper tool that swaps cryptocurrency wallet addresses. The campaign has affected users drawn to pirated software, highlighting the risks of downloading from unverified sources.

Researchers have identified over 280 malicious applications that exploit optical character recognition (OCR) technology to steal cryptocurrency wallet credentials from compromised Android devices. These apps, disguised as legitimate services, harvest sensitive information like text messages and images but are not found on Google Play, indicating distribution via phishing and dubious websites. The malware uses OCR to extract mnemonic phrases from images, making it easier for attackers to access cryptocurrency wallets. A McAfee researcher uncovered a server with stolen data due to poor security configurations, revealing the attackers' focus on capturing recovery phrases. The malware has evolved to use sophisticated communication methods and obfuscation techniques, complicating detection efforts. Initially targeting South Korea, the malware's recent emergence in the UK indicates a geographic expansion of its operations.

Criminal enterprises are targeting Chinese businesses using a Remote Access Trojan (RAT) called ValleyRAT, which can take control of infected Windows endpoints. Researchers at FortiGuard identified this malware, which poses a threat to sectors like ecommerce, finance, sales, and management. The initial breach often occurs through phishing tactics, with attackers distributing loaders disguised as Microsoft Office files. Once inside a system, ValleyRAT uses a multi-stage approach to execute components in memory, making detection difficult. The malware can monitor activities and deploy plugins based on the attackers' goals. The group behind these attacks is known as "Silver Fox," which has previously targeted Chinese organizations. In spring 2023, Weibu Online reported efforts to track Silver Fox, which used SEO poisoning to enhance the visibility of their phishing sites. While the origins of Silver Fox are unclear, some experts suggest they may be of Chinese descent. Businesses are advised to keep antivirus systems updated and educate employees about phishing risks to mitigate breaches.
