Researcher to Release Free Attack Obfuscation Tool

Cybercrime gang FIN7, aka Carbanak, spotted hiding behind another Windows function, according to research to be presented at Black Hat Asia next month.

Advanced nation-state and cybercrime groups increasingly are hiding behind legitimate Microsoft Windows functions to mask their hacks - and their latest method ups the ante in abuses of the basic command prompt.

The FIN7, aka Carbanak, cybercrime gang known for attacking banks and most recently, the hospitality and restaurant industries, last year was spotted by FireEye exploiting the cmd.exe Windows binary. The unique use of their technique inspired Daniel Bohannon, senior applied security researcher for Mandiant, a FireEye company, to create a tool that helps organizations better defend against attackers who hide their payloads behind the legitimate Windows commands.

"The way they used the [command process] blew my mind, so from that point forward, I started looking at command-execution obfuscation," Bohannon says of FIN7's activity.

The command prompt obfuscation method is another twist in what researchers refer to as "living off the land," or fileless malware attacks, where attackers use native Windows tools on a victim's machine to hide their activity and malware from detection-based security tools and whitelisting. "Attackers don't need to drop custom malware on disk. They can use native tools and run everything in memory," Bohannon explains.
