Samirbous bf49a90eb0 [New] Sensitive Identity File Open by Suspicious Process via Auditd (#5982)
* [New] Sensitive Identity File Open by Suspicious Process via Auditd

Detects Auditd opened-file reads on sensitive root and cluster paths (Kubernetes token mounts, kubelet and admin kubeconfig, PKI material, shadow, root SSH keys, root cloud CLI and Docker config) when the process looks like common copy or scripting utilities or the binary runs from temp or run staging. User home paths are excluded so file watches
stay explicit and aligned with auditd:

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)
