<p>Detection focuses on abnormal or unauthorized cloud instance creation events. From a defender’s perspective, suspicious behavior includes VM/instance creation by rarely used or newly created accounts, creation events from unusual geolocations, or rapid sequences of snapshot creation followed by instance creation and mounting. Unexpected network or IAM policy changes applied to new instances can indicate adversarial use rather than legitimate provisioning.</p>

Log sources and channels

Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.

Mutable elements

Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.

FieldDescription
UserContextIAM user, service account, or role creating the instance. Tuned to allowlist known automation services.
GeoLocationRegion or source IP where the creation request originates. Helps detect cross-region or unusual location abuse.
RateThresholdNumber of instances created per user or account in a time window. Tuned for environments with elastic scaling.
TaggingPolicyExpected tags (e.g., owner, purpose, cost center) for new instances. Deviations may indicate adversarial creation.
