Good day everyone!
Today's #readoftheday is brought to you by AnyRun and describes a campaign that has targeted Chinese-speaking users and distributing the malware known as #ValleyRAT. A RAT, which stands for remote access trojan, is a type of malware that is designed to allow the attacker to access and control a victim's machine. This one targets the Windows operating system and employs a range of techniques to evade detection and is delivered when the first-stage loader is disguised as a legitimate application like Microsoft Office. When the unsuspecting victim executes the malware a decoy document is deployed and the executable loads the shellcode that advances the attack to the next stage.
Attackers have long since used files that are masqueraded as legitimate process, executables, and so on as well as using the technique of dropping a decoy document when the user executes malware. The idea here is a layered effect: one, the adversary abuses the trust a user has for legitimate file names and THEN provides something that the victim may have been expecting, basically giving the victim something as to not raise an alarm. This may be the delay that the attacker needs to get a stronger foothold in the environment and gain persistence.
Stay tuned for your threat hunting tip of the day, but until then, Happy Hunting!
