500ms to midnight: XZ A.K.A. liblzma backdoor

Elastic Security Labs published detection resources for the XZ Utility backdoor, including YARA rules, osquery queries, and KQL searches to help identify systems with potential compromises.

Why it matters: Systems administrators and security teams running affected XZ/liblzma versions need immediate detection tools to assess exposure in their environments.
