| Layer | What the Binary Does | |-------|-----------------------| | | Calls WinMain → CreateThread for multiple payloads (keylogger, network, persistence). | | Persistence | Creates a registry Run key under HKCU\Software\Microsoft\Windows\CurrentVersion\Run pointing to itself; also drops a copy in %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup . | | Network | Connects to hard‑coded C2 domains (often using fast‑flux DNS) via HTTP/HTTPS over port 80/443. Uses AES‑256‑CBC encryption for payloads. | | Data collection | Captures keystrokes, screenshots, clipboard contents, and extracts stored credentials from browsers (Chrome, Edge, Firefox) and FTP clients. | | File manipulation | Searches for files with extensions like .docx , .xlsx , .pdf , compresses them into a ZIP archive, and uploads them to the C2 server. | | Self‑defense | Checks for sandbox artifacts (e.g., presence of VMware , VirtualBox drivers), delays execution if detected, and can delete itself after a successful exfiltration. |
