Backdoor used in malicious email campaigns. It is delivered via a fake CryptoPro installer chain using MSI/CAB files and DLL side-loading. It communicates with C2 servers and can execute PowerShell commands, download and run EXE files, download and run DLLs via rundll32, and register/execute DLL COM objects via regsvr32. The final payload in this campaign is a modified x64 version of CapDoor.
