Also shipped to the compromised devices are two backdoors named Giddome and Pterodo, both equally of which are trademark Shuckworm instruments that have been regularly redeveloped by the attackers in a bid to continue to be in advance of detection.
At its main, Pterodo is a Visual Simple Script (VBS) dropper malware with capabilities to execute PowerShell scripts, use scheduled duties (shtasks.exe) to maintain persistence, and down load additional code from a command-and-handle server.
