Ursnif — 恶意软件档案
Ursnif/Gozi ISFB banking trojan 2007. magic.js 1 string max obfuski. kpmg/thelancet camouflage. Discord CDN. Man-in-browser.
技术细节
Ursnif (Gozi/ISFB) is one of the oldest banking trojans, active since 2007. Source code leaked 2010 and 2015 spawning numerous variants: ISFB, RM3, LDR4. Man-in-the-browser attacks: form grabbing, video capture of banking sessions, web injections. C2 uses RSA-1024 encrypted HTTPS with domain generation algorithm (DGA) as fallback. RSA-2048 for config encryption, custom binary protocol. Anti-analysis: timing-based sandbox evasion, VMware/VirtualBox artifact detection. LDR4 variant (2022) dropped banking features to focus purely on ransomware delivery. Operated by TA544 (Narwhal Spider) in Italy, and by TA551 (Shathak) in Japan. Uses HTTPS for exfiltration with binary data format.
