T1082 — System Information Discovery

Tactic: Discovery · Platforms: ESXi, IaaS, Linux, macOS, Network Devices, Windows

An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture. Adversaries may use this information to shape follow-on behaviors, including whether or not the adversary fully infects the target…

detection:
  selection:

    userIdentity.type: 'AWSService'

  condition: selection and not filter_service_principal

falsepositives:
  - These are among the most frequent read-only API calls made by CLI tooling, CI/CD pipelines, and inventory systems, so this rule is only useful for volume-based anomaly detection, not single-event alerting.
