Quick Takeaways Huntress warns of a widespread campaign against SonicWall SSL VPN accounts, with over 100 accounts compromised across 16 environments mainly on October 4-10, using valid credentials rather than brute-force attacks. The attackers, appearing to log in from the same IP, often disconnected after initial access or conducted reconnaissance, including network scanning and local Windows account access. This activity follows SonicWall’s September data breach involving cloud backup files, but Huntress currently sees no direct link between the two incidents. Recommendations include disabling remote management, resetting credentials, monitoring logs, enabling multi-factor authentication, and revoking external access to mitigate further risk.…

Essential Insights Astaroth banking Trojan now uses GitHub’s raw content service to host encrypted configuration files, aiding in evasion from traditional detection methods. The malware delivery relies on spear-phishing with malicious Word documents containing obfuscated macros that download and execute loader files. Once activated, the malware fetches its configurations from GitHub, decrypts them in memory, and employs stealth techniques like process hollowing and process masquerading to stay hidden. Targeting primarily European and North American banking clients, Astaroth facilitates credential theft, unauthorized transfers, and ransomware deployment, with ongoing detection recommended through monitoring GitHub raw content access. Problem Explained A newly emerging…
