TrickBot Hakkında

TrickBot (TrickLoader), 2016'dan beri aktif modüler bankacılık trojanıdır. Dyre/Dyreza'nın halefidir. Web enjeksiyonu, credential hırsızlığı, e-posta toplama ve lateral movement yetenekleri olan modüler mimariye sahiptir. Uzun yıllar boyunca Conti ransomware için birincil dropper olmuştur. 2022'de operasyonel olarak dağıtıldığı düşünülmektedir.

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).
