* [New] Detection Alert on a Process Exhibiting CPU Spike
This rule correlates security alerts with processes exhibiting unusually high CPU utilization on the same host and process ID within a short time window. This behavior may indicate malicious activity such as malware execution, cryptomining, exploit payload execution, or abuse of system resources following initial compromise.

rules/
Rules within this folder are organized by solution or platform. The structure is flattened out, because nested file hierarchies are hard to navigate and find what you're looking for. Each directory contains several .toml files, and the primary ATT&CK tactic is included in the file name when it's relevant (i.e. windows/execution_via_compiled_html_file.toml)
