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.
