Title: Video game cheats, mods, used to hide malware
Description: Cisco Talos recently discovered a new campaign targeting video game players and other PC modders. Talos detected a new cryptor used in several different malware campaigns hidden in seemingly legitimate files that users would usually download to install cheat codes into video games or other visual and game modifications (aka "mods"). The cryptor uses Visual Basic 6 along with shellcode and process injection techniques. The cryptor in this campaign uses several obfuscation techniques that makes it difficult to dissect and could pose a challenge for security analysts not familiar with Visual Basic 6. Video game players may opt to download certain cheats or modifications (aka "mods") to change the way some games are presented. The adversaries use these gaming and OS modding tools to attach hidden malware to infect their victims.
