#ESETResearch discovered that #LuckyMouse/#APT27 used a code-signing certificate belonging to VMPsoft, the developer of the VMProtect packer. The signed file is a loader for the SysUpdate backdoor (aka Soldier). We notified VMPSoft of this compromise 1/4

Pivoting on the certificate, we found genuine VMPsoft binaries and a sample of SysUpdate signed and packed with VMProtect. Since LuckyMouse rarely use VMProtect, it is possible that they also stole VMProtect packer when they got the digi certificate. 2/4

While the certificate is still valid, we have notified GlobalSign.
