Shadow Copy Deletion or Resizing Using OS Utilities
This rule detects attempts to delete or resize Volume Shadow Copies using various Windows operating system utilities. Adversaries often delete shadow copies to prevent system recovery and hinder forensic analysis, especially in ransomware attacks. The rule specifically looks for command-line executions of `powershell.exe`, `pwsh.exe`, `wmic.exe`, `vssadmin.exe`, `diskshadow.exe`, and `wbadmin.exe` with arguments indicating shadow copy deletion or resizing operations. This includes commands like 'shadow delete', 'wbadmin delete catalog', and 'vssadmin resize shadowstorage'.
