HyperBro

Actor(s): EMISSARY PANDA


HyperBro is a RAT that has been observed to target primarily within the gambling industries, though it has been spotted in other places as well. The malware typically consists of 3 or more components: a) a genuine loader typically with a signed certification b) a malicious DLL loader loaded from the former component via DLL hijacking c) an encrypted and compressed blob that decrypts to a PE-based payload which has its C2 information hardcoded within.
