Re: "Transparent"
It's because of how the exploit drops directly into RAM bypassing any security software. This teqnique is nothing new. The dropper can be encoded dozens of times to such a point that even using the most advanced file heuristic analysis it goes undetected.  It also has polymorphic properties so it is capable of self modifying it's own code to further evade detection. This makes signature based detection also useless. Another method used is covert application channels where shell code is injected into a file such as calc.exe or system file and the digital file signature is also forged. All connections established by the RAT are fully encrypted utilizing Reverse_TCP connection method. Because the infected system is 'phoning home' it in most cases is allowed through the firewall. One way to prevent this connection attempt is to have proper implicit deny ACLs in place. However, one would have to be able to monitor and identify the outgoing encrypted traffic or any network traffic for that matter and verifiy it is in fact legitimate. Constant whitelisting would need to be properly applied without the distruption of 'Normal' traffic. I do not see any practical solution to this in the near future.

Re: "Transparent"
The transparency or "invisibility" comes through the faulty certificate and, possibly, from other characteristics that make it behave like an innocent file.

Security Measures
What security measures and best practices should be used for a trojan that is detectable only via network forensics and specialized tools that are capable of detecting suspicious activity on endpoint systems? Also, what are these "specialized tools"?
