What it detects

This rule detects use of ProcDump to capture the memory of the LSASS process for offline credential extraction. Alloy Taurus operators dumped LSASS with ProcDump during their campaign against a Southeast Asian government target, and while ProcDump is a legitimate Sysinternals tool this specific target makes it a strong credential-access signal.
