Microsoft Defender for Endpoint can act as a behavioural sensor, surfacing process creation, suspicious handle access, LSASS targeting, and command-line anomalies through its Advanced Hunting query layer. Effective detection requires correlating endpoint telemetry with identity and sign-in logs — a single suspicious PowerShell session gains significance when followed by unusual authentication activity. Practical guidance covers hunting for LSASS access from non-standard processes, encoded PowerShell commands, and suspicious process chains, as well as tuning alerts using context-aware allow-lists rather than broad exclusions. Attack surface reduction rules, tamper protection, and credential protection features improve signal quality. The post also addresses operationalising detections for small security teams, mapping coverage to MITRE ATT&CK, and iteratively measuring false positive rates and missed detections. ## Full article daily.dev links to this article rather than hosting it.
