* [New] Elastic Defend Alert Followed by Telemetry Loss Detects when an Elastic Defend endpoint alert is generated on a host and is not followed by any subsequent endpoint telemetry (process, network, registry, library, or DNS events) within a short time window. This behavior may indicate endpoint security evasion, agent tampering, sensor disablement, service termination, system crash, or malicious interference with telemetry collection following detection. * Update defense_evasion_missing_events_after_alert.toml * Apply suggestion from @Mikaayenson Co-authored-by: Mika Ayenson, PhD <Mikaayenson@users.noreply.github.com> --------- Co-authored-by: Mika Ayenson, PhD <Mikaayenson@users.noreply.github.com>
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)
