Signatures

Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Query firmware table information (likely to detect VMs)
Checks for available system drives (often done to infect USB drives)
Creates files inside the system directory
Deletes files inside the Windows folder
Drops PE files
Drops PE files to the windows directory (C:\Windows)
Drops files with a non-matching file extension (content does not match file extension)
Found dropped PE file which has not been started or loaded
PE file contains sections with non-standard names
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
