Google Threat Intelligence and Mandiant report attackers using stolen IAM credentials, service account keys, GitHub tokens and exposed API keys to run up enterprise LLM bills, in some cases to $1 million. The credentials are the familiar non-human kind; what’s new is how fast they turn into money, with fraudulent charges topping $100,000 in a single day. If spend alerts on your AI accounts go to finance rather than security, this is a good week to change that.

Google reports LLMjacking attacks using stolen cloud credentials run up charges near $1 million
Google Threat Intelligence and Mandiant found attackers hijacking enterprise LLM access via stolen IAM credentials, service account keys, GitHub tokens and exposed API keys, with some organizations billed up to $1 million. Practitioners should treat these non-human credentials as primary targets, since fraudulent charges can exceed $100,000 in one day.

Delinea blog: AI agent queries are logged under developer credentials, not the agent
Delinea says audit trails attribute actions by AI agents to the human whose credentials the agent used, so the log cannot show who actually ran a query. It cites its 2026 report quoting Gal Diskin on this limitation.

Aembit explains AI agent registries as an inventory layer for enterprise identity security
Aembit's guide describes agent registries as catalogs of agents, owners and identity provider details, populated through CI/CD or platform self-registration using A2A Agent Cards. IAM teams can use the registry metadata as input for access policies on non-human identities.

CyberScoop op-ed: CISA 2030 strategy exposes persistent machine credentials and unchecked AI agent permissions
An op-ed by OmniTrust CEO David Sequino argues that CISA's new strategy runs into stale device, contractor and machine-identity approvals, and AI agents holding excessive permissions. It urges reassessing access when suppliers or roles change, enforcing limits on agent actions, and testing that credentials can be revoked safely.

Vendor moves
CrowdStrike to acquire Fiddler and Dreadnode, adding AI agent observability and testing
CrowdStrike signed deals to buy Fiddler AI (agent observability) and Dreadnode (pre-deployment AI attack testing), and announced an AI Kill Switch that lets humans stop agents at runtime. Agents can hold valid credentials yet misbehave, so agent decision records and stop controls now sit alongside credential governance.

NIST SP 800-63B-4 drops security questions as an account recovery method
NIST SP 800-63B-4 no longer recognizes knowledge-based security questions as an authenticator and recognizes four recovery methods instead: saved codes, issued codes, recovery contacts and repeated identity proofing. Recovery flows relying on security questions must migrate to one of these or document a risk analysis.

WorkOS explains password spraying and why per-account lockouts miss it
WorkOS published a guide on password spraying, which tries a few common passwords across many accounts so no single account trips a lockout. It advises detecting many accounts failing on one password fingerprint and blocking common or breached passwords.
