• Polymorphic Engine: Each generated malware sample had a unique hash and code structure.
• Anti-Sandbox & Anti-VM: Baget-checked if it was running in a virtualized environment (VirtualBox, VMWare) or a sandbox; if so, it would sleep indefinitely or exit.
• Persistence Mechanism: It used scheduled tasks, registry run keys, and WMI event subscriptions.
• Process Hollowing: It could inject the decrypted payload into legitimate Windows processes like explorer.exe or svchost.exe.
