ToolShell GPO Ransomware Deployment
Detects modifications to Group Policy Objects (GPOs) that enable script processing. Threat actors, such as Storm-2603, abuse GPOs to deploy ransomware (like Warlock) by adding malicious startup or logon scripts. This detection identifies when the "Group Policy Scripts" client-side extension is added to a GPO, which is a key step in this attack chain. This activity is logged under Event ID 5136 on Domain Controllers.
