What it detects

This rule detects a process opening a handle to LSASS with memory-read access rights typical of credential-dumping tooling, while excluding the small set of legitimate operating-system components that normally interact with LSASS. Access to LSASS memory is a top credential-access technique in the Red Canary Threat Detection Report, yielding plaintext secrets and hashes for lateral movement. Alerting on non-system readers of LSASS surfaces dumping attempts across custom and off-the-shelf tools.
