Sistem Temizleme Rehberi
- Sistemi ağdan ayırın — Loader başka zararlı yazılım indiriyor olabilir
- İndirilen tüm payload'ları analiz edin
- Tüm ağ trafiğini inceleyin, şüpheli bağlantıları kesin
- Antivirüs ile tam tarama yapın
- Sistem yenileme düşünün

技术细节
IcedID (BazarLoader) is a banking trojan and loader first observed 2017. Man-in-the-browser attacks targeting banking credentials via web injections. BazarLoader component: delivers Ryuk, Conti, and other ransomware payloads. Uses HTTPS with TLS for C2, custom binary protocol. Delivered via malspam (Office macros, password-protected archives). Notable for forked distribution: Standard IcedID vs. Lite variant (reduced banking features). Lite/BackConnect IcedID evolved to focus solely on ransomware delivery. C2 uses high entropy DGA-like domains with .com TLD.
