Technical Details


Installation to system

The trojan will add an entry to the Windows registry aiming at being run every time Windows starts. The key will be:

[HKLM\Software\Microsoft\Windows\CurrentVersion\Run\UsbD]
 

Which will point where the file is initially run from.

Spreading in

Cidra.D does not spread by itself. It was massively spammed.

Payload
