What it detects

This rule detects invocation of the Invoke-PowerDump credential dumping function inside a PowerShell session as used during the BlueSky ransomware intrusion to harvest local account hashes and this matters because Invoke-PowerDump is offensive tooling with no legitimate administrative purpose and its execution indicates active credential access.
