SideWinder Adopts ClickOnce and PDF Lures in 2025 Campaign

🛡️ Trellix researchers report that the threat actor SideWinder has evolved its tradecraft in 2025 by adopting a PDF + ClickOnce infection chain alongside previously used Word exploit vectors. Four spear‑phishing waves from March through September targeted a European embassy in New Delhi and organizations in Sri Lanka, Pakistan and Bangladesh, using tailored lures and a signed MagTek executable that side‑loads a malicious DLL. The DLL decrypts and runs a .NET loader (ModuleInstaller) which fetches StealerBot, a .NET implant capable of reverse shells, delivering additional payloads, and collecting screenshots, keystrokes, credentials and files.

Google: Brickstorm malware stole data from U.S. orgs

🔒 Google researchers warn that the Go-based Brickstorm backdoor was used in prolonged espionage against U.S. technology, legal, SaaS, and BPO organizations, averaging a 393-day dwell time. Suspected activity from the UNC5221 cluster involved deploying the malware on appliances lacking EDR protection such as VMware vCenter/ESXi, where it acted as a web server, SOCKS proxy, file dropper, and remote shell. Operators used techniques like a malicious Java Servlet Filter (Bricksteal), VM cloning, and startup-script modifications to capture credentials and move laterally, then tunneled to exfiltrate emails via Microsoft Entra ID Enterprise Apps. Mandiant published a scanner and YARA rules to aid detection but cautions it may not catch all variants or persistence.
