New Pony Loader Obfuscation Technique via Smoke Loader

Cyber actors are leveraging the infamous Smoke Loader downloader to deliver several malware families to include: Zeus, Neutrino, Chthonic banking trojan and crypto mining software.  The RIG exploit kit (EK) developers are currently using this downloader to deliver the Monero coin miner.   Attackers are now delivering the Pony/Fareit malware via the PowerArchiver compressor (XXEncode 0.0), which significantly reduces the rate of detection by anti-virus vendors (less than six vendors) and the file format is detected as a text file.    Wapack Labs identified the secondary command and control (C2) infrastructure which continues to be developed by operators.
