技术细节

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.
