Permanent link Tool: BabyShark

TypeReconnaissance, Backdoor
DescriptionBabyShark is Microsoft Visual Basic (VB) script-based malware family first seen in November 2018. The malware is launched by executing the first stage HTA from a remote location, thus it can be delivered via different file types including PE files as well as malicious documents. It exfiltrates system information to C2 server, maintains persistence on the system, and waits for further instruction from the operator.

(Palo Alto) Based on our research, it appears the malware author calls the encoded secondary payload “Cowboy” regardless of what malware family is delivered.

In our analysis, we found BabyShark attacks were using KimJongRAT and Gh0st RAT as the encoded secondary payload and thus were the “Cowboys”.
