Threats Tagged 'python-based'

A Python-based Malware-as-a-Service builder enables operators to generate customized Windows infostealer executables. The system comprises a builder component and an embedded payload, using Nuitka or PyInstaller compilation to evade detection. The builder features automatic dependency installation, webhook configuration with XOR and Base64 encoding, and multiple compilation backends. The payload targets Chromium and Firefox browsers, extracting credentials, cookies, and credit card data. It harvests Wi-Fi passwords, Discord tokens, and Roblox session cookies while employing anti-analysis techniques including debugger detection, VM process blacklisting, disk size checks, and timing evasion. Persistence is established through registry Run keys and scheduled tasks. All stolen data is packaged into in-memory ZIP archives and exfiltrated via attacker-controlled webhooks, following a scalable affiliate model.
