Description

Detects a single AWS principal invoking Amazon Bedrock models from three or more countries and three or more source IPs within the lookback window. LLMjacking operators often distribute stolen AWS credentials across proxies or resell them to multiple buyers, which produces inference traffic for one identity from many unrelated locations.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

The rule states no platform. This is derived from the 2 ATT&CK techniques it maps to.

Known benign triggers

  • Globally distributed applications or CI runners that call Bedrock with one shared IAM user or role. Prefer per-region identities, or raise the country threshold for these principals.
  • Users on VPNs or privacy relays that rotate exit countries. Corroborate with ASN and user agent before acting.
