Process Memory Dump Via Dotnet-Dump

Detects the execution of "dotnet-dump" with the "collect" flag. The execution could indicate potential process dumping of critical processes such as LSASS.

Detection logic

Detection requirements

Platform: Linux macOS Windows
The rule states no platform. This is derived from the ATT&CK technique it maps to.
Log source product: windows
Log source category: process_creation

Known benign triggers

Process dumping is the expected behavior of the tool. So false positives are expected in legitimate usage. The PID/Process Name of the process being dumped needs to be investigated
