Legitimate RMM Abuse in Crazy Ransomware Intrusions

Huntress investigations reveal:
• Net Monitor for Employees deployed via msiexec
• SimpleHelp persistence via PowerShell
• Disguised binaries (OneDriveSvc.exe, vhost.exe)
• Defender service tampering
• Crypto wallet keyword monitoring
• SSL VPN credential compromise as initial access

The adversary leveraged redundancy across remote access tools to guarantee persistence even if one method was removed.

Key takeaway: Detection must focus on anomalous deployment patterns of legitimate administrative tools - not just malware signatures.

Are you correlating RMM installations with VPN authentication anomalies?
