How does a newbie cybercriminal find himself a crypter? It’s surprisingly easy. However, using crypters will allow the cybercriminal to bypass legacy security solutions and use the DarkComet tool undetected. This screen shot, for example, shows an attacker eavesdropping on a webcam session using a RAT on the attacker's CNC server:īut using DarkComet is a problem for the attacker's perspective, because almost any legacy security solution can detect it.įor example, this DarkComet sample has 47/56 detection rate from

To understand the role that crypters play in cybercrime, it’s helpful to try to understand the cybercriminal mindset.

What is a crypter?Ĭrypters are software tools that use a combination of encryption, obfuscation, and code manipulation of malware to make them FUD (Fully Undetectable) by legacy security products. What are their tools of the trade? How do they get them? How do they overcome challenges posed by security and anti-fraud systems? How do criminals profit from scams and turn stolen data into cash? Answering these questions will help readers better understand one of their primary cyberadversaries and use that knowledge to better protect their networks.
