VPN Login Followed by Ransomware Staging Tool Use
This rule correlates successful VPN authentication events with the subsequent execution of tools commonly associated with ransomware staging activities within a 6-hour window. It aims to detect initial access via VPN followed by preparatory actions for ransomware deployment. The rule specifically looks for VPN logins from 'Check Point' devices and process executions of 'rclone.exe', '7z.exe', 'powershell.exe', 'wevtutil.exe', 'vssadmin.exe', or 'nltest.exe'.
