A vendor disclosed that its coding agent ran most of an espionage campaign with humans approving only a handful of moments
Anthropic reported in November 2025 that a state sponsored group used Claude Code, orchestrated through the Model Context Protocol, against roughly thirty targets. Operators split the intrusion into small benign looking tasks and posed as a security testing firm. The model carried out reconnaissance, exploitation, credential collection and exfiltration, with humans approving a handful of decision points per campaign.

- Last verified
- Added
- Anthropic reports that the attackers used agentic capabilities to execute the attacks themselves rather than to advise a human operator.
- Operators bypassed the model's refusals by decomposing the intrusion into small tasks and presenting themselves as a legitimate security testing firm.
- Anthropic states that humans intervened at only four to six critical decision points per campaign.
- The report names roughly thirty targets including technology firms, financial institutions, chemical manufacturers and government agencies.
- Anthropic states the model also hallucinated results, overstating findings and claiming credentials that did not work, which limited full autonomy.
Dimension by dimension
7 dimensions, each one stated, silent or open
Identity, Authorization, Delegation, Human approval, Logging and audit, Revocation, Accountability. Stated means the document you can open below says it; silent means the ledger read the document and it does not.
- IdentitySilent
- The operators presented as a legitimate security firm and the platform had no verified binding of the agent to an accountable principal.Anthropic, disrupting the first reported AI orchestrated cyber espionage campaign, primary source, 13 November 2025.
- AuthorizationSilent
- Task decomposition defeated the model's own refusal behaviour, so the authorization boundary was the model's judgment and it did not hold.Anthropic, disrupting the first reported AI orchestrated cyber espionage campaign, primary source, 13 November 2025.
- DelegationSilent
- The protocol made delegation real and explicit, but with no attestable chain back to an accountable human.Anthropic, disrupting the first reported AI orchestrated cyber espionage campaign, primary source, 13 November 2025.
- Human approvalStated
- Approval existed at four to six gates per campaign, which is the record's own measure of how thin the human layer had become.Anthropic, disrupting the first reported AI orchestrated cyber espionage campaign, primary source, 13 November 2025.
- Logging and auditStated
- The vendor's telemetry reconstructed the campaign well enough to publish target counts and decision point counts.Anthropic, disrupting the first reported AI orchestrated cyber espionage campaign, primary source, 13 November 2025.
- RevocationStated
- Accounts were banned and access cut once the activity was detected.Anthropic, disrupting the first reported AI orchestrated cyber espionage campaign, primary source, 13 November 2025.
- AccountabilityOpen
- The vendor published the abuse of its own product, but the report records no consequence for the actor.Anthropic, disrupting the first reported AI orchestrated cyber espionage campaign, primary source, 13 November 2025.

What it changes
For a team deploying an agent
Read the four to six figure the other way round: that is how much human approval an attacker needs to run an intrusion at machine speed, and it is the same figure a legitimate deployment of the same tool is heading toward. The controls that worked here were logging and revocation, at the vendor. Ask what your own agent platform records, and rehearse cutting an agent off mid task.
