Vidar has transformed from a credential stealer into a multi-stage, stealth-driven infostealer that uses Go-compiled droppers, a living‑off‑the‑land execution chain (WScript → PowerShell → ConHost → RegAsm), fileless reflective .NET loading, and social-engineering lures (fake GitHub repos, CAPTCHAs, game cheats) to harvest crypto wallets and password managers and exfiltrate data via Telegram.
