Sistem Temizleme Rehberi

  1. Sistemi ağdan ayırın — Loader başka zararlı yazılım indiriyor olabilir
  2. İndirilen tüm payload'ları analiz edin
  3. Tüm ağ trafiğini inceleyin, şüpheli bağlantıları kesin
  4. Antivirüs ile tam tarama yapın
  5. Sistem yenileme düşünün

Détails techniques

SmokeLoader (Dofoil/Smoke Bot) is a modular loader/downloader active since 2011. Primary function: download and execute additional payloads (Emotet, TrickBot, FormBook, Ursnif). Heavy obfuscation: string encryption (RC4+XOR), process injection via APC, code injection. Heaven's Gate technique: switches from 32-bit to 64-bit mode to evade WoW64 hooks. Anti-analysis: CPUID-based VM detection, process listing for analysis tools, timing checks. Uses process hollowing to inject into explorer.exe or svchost.exe. C2 communication: RC4-encrypted HTTP POST requests with bot ID, campaign ID. Sold as pay-per-install (PPI) service on underground forums (~$400/1000 installs). Frequently updated to bypass detection, >100 variants documented.
