Samirbous 116f48ccda [New] Elastic Defend Alert from Package Manager Install Ancestry (#5905)
* [New] Elastic Defend Alert from Package Manager Install Ancestry

Detects Elastic Defend alerts (behavior, malicious file, memory signature, shellcode) where the alerted process has a package-manager install context in its ancestry: npm (Node.js), PyPI (pip / Python / uv), or Rust (cargo). Install-time spawn chains are a common path for supply-chain and postinstall abuse; this Higher-Order rule surfaces Defend alerts
whose process tree includes such activity for prioritization.

* Update initial_access_elastic_defend_alert_package_manager_ancestor.toml

* Update rules/cross-platform/initial_access_elastic_defend_alert_package_manager_ancestor.toml

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)
