DGA-Tarzı Dosya Adı
55ryoipjfdr.exe -- "55" = sayısal önek -- "ryoipjfdr" = rastgele görünen 9 karakter (DGA output gibi) -- Sandbox analiz araçlarını karıştırır (bilinen imza yok) -- Yeniden adlandırılan dropper farklı hash üretir
UrlIsNoHistoryW: Bankacılık Tarayıcı Hook!
UrlIsNoHistoryW (wininet.dll) -- "URL Is No History" = IE'nin bu URL'yi geçmişe ekleme bayrağı -- TrickBot bu API'yi hook'lar: 1. Kurban bankacılık sitesine giriyor 2. UrlIsNoHistoryW çağrıldığında TrickBot araya giriyor 3. URL, kimlik bilgileri, form verisi kaydediliyor 4. Web inject: sahte banka sayfası kurbanına gösteriliyor -- Bu import YALNIZCA bankacılık trojanlarında görülür -- Meşru yazılımların bu fonksiyonu import etmesi gerekmez
WTSSetUserConfigW: Terminal Servis Yanal Hareketi
WTSSetUserConfigW (wtsapi32.dll) -- WTS = Windows Terminal Services (Uzak Masaüstü) -- SetUserConfig = terminal oturumu kullanıcı konfigürasyonu değiştirme -- TrickBot bunu kullanır → kurumsal RDP/RDS ortamlarına yayılır -- Bankacılık hedefi + RDP yanal hareket = tam kurumsal saldırı zinciri

TrickBot — Malware Profile
TrickBot modular banking trojan. DGA filename. WTSSetUserConfigW RDP targeting. RegUnLoadKeyA registry hive dump.
Technical Details
TrickBot is a modular banking trojan and loader developed by WIZARD SPIDER since 2016. Evolved from Dyre banking trojan with modular architecture allowing plugin-based functionality. Modules: pwgrab (credential theft), networkdll (network reconnaissance), shareDll (SMB spread), tabDll (browser form grabbing), vncDll (remote access), mworm/nworm (propagation). Used extensively to deliver Ryuk and Conti ransomware. C2 communication: HTTPS with custom User-Agent strings. Infrastructure disrupted by Microsoft/ESET/Symantec/CISA in October 2020. Key operators arrested/sanctioned; infrastructure rebuilt multiple times. Shifted focus from banking to enterprise ransomware delivery (2019-2022).
