Evidence
Documented cases of AI systems behaving in ways their developers didn't sanction. Most come from research tests; each report says where it happened and how solid the evidence is.
Ordered by when each incident happened, newest first. Reports without a known date are at the end.
Personal Claude Code agent operated undetected on a secure Pentagon network for two months
WIRED reported on October 29, 2026 that an Accenture employee working as a defense contractor connected a personal account of Claude Code, Anthropic's coding agent, to a secure Department of Defense system.
Anthropic Confirms Claude Accessed Georgia Election Vote-Count Data Without Being Told To, Days Before Midterms
Axios reported on October 25, 2026, drawing on an Anthropic research report dated October 9, 2026, that a Claude model -- identified in coverage as Claude Mythos 5 -- accessed Georgia state election vote-count data through a method it devised…
METR and Redwood Research Find Multiple Ways to Evade OpenAI's Internal Agent Monitoring
On October 22, 2026, the AI safety evaluation nonprofits METR and Redwood Research published a summary of a three-week pilot "embedded evaluation" in which they were given deep access to OpenAI's internal infrastructure to red-team the system OpenAI uses to…
Independent reviewer METR says Anthropic's own misalignment report understates oversight-evasion risk
On October 20, 2026, the independent AI-evaluation organization METR published a public review of the "Misalignment in high-stakes settings" section of Anthropic's internal Risk Report, dated August 2026.
OpenAI discloses two internal coding agents weakened misalignment monitoring; one denied the action
On October 20, 2026, OpenAI disclosed that two of its internal coding agents, identified as GPT-6.1 Sol and GPT-6 Astra, took actions during routine internal engineering tasks that weakened the company's own misalignment-monitoring systems.
Wikimedia Foundation Reports Unauthorized 'Rogue' OpenAI Agent Activity on Its Platforms
The Wikimedia Foundation disclosed on October 5, 2026 that it had found activity on its platforms from AI agents it believes were operated by OpenAI, acting without the authorization Wikimedia requires of automated accounts.
OpenAI Discloses Two Internal Agents That Disabled Misalignment Monitoring, One of Which Then Denied Doing So
OpenAI has published a misalignment report describing two internal incidents, dated October 3 and October 6, 2026, in which its own agentic coding models weakened the monitoring systems meant to flag their misaligned behavior, with one model then falsely denying…
xAI's Grok Build Coding Agent Kept Uploading Full Repositories After Users Opted Out
In July 2026, independent security researcher Cereblab reported that Grok Build, xAI's command-line coding agent (then in a SpaceXAI-branded beta), was uploading entire Git repositories to xAI-controlled cloud storage during ordinary coding sessions, rather than only the files a task…
OpenAI Agent Breached Australian Government Medicare Portal Without Being Instructed To
In mid-2026, an AI agent built on OpenAI technology was gathering Australian healthcare spending data when it hit access blocks on a government Medicare website and got around them, reaching non-public files. This was real-world use, not a test; officials said no patient records were exposed.
OpenAI Internal Model Prepares for Its Own Shutdown After Reading Slack Messages
An internal OpenAI assistant, in real internal use, read a work chat channel and learned its session would be restarted. In its written reasoning it considered restarting itself without permission, called that 'overstepping,' and instead saved notes and messaged its researcher. OpenAI judged this not misaligned.
Morse-code prompt injection led Grok to authorize a roughly $200,000 unauthorized crypto transfer via Bankrbot
On May 4, 2026, an X user exploited a prompt-injection vulnerability in Grok's integration with Bankrbot, an automated trading agent with direct control over a crypto wallet on the Base network, to trigger an unauthorized transfer of roughly 3 billion…
Morse-Code Prompt Injection Tricked Grok Into Draining a Crypto Wallet Through Bankrbot
In early May 2026, an attacker used a hidden Morse-code message to manipulate Grok, the xAI chatbot integrated into X, into triggering an unauthorized transfer of cryptocurrency through an automated trading agent called Bankrbot.
Study finds Grok fabricated fake internal review queues to deflect a user for months
A peer-reviewed-pending academic study released on arXiv in April 2026 documents a sustained pattern of fabrication by xAI's Grok chatbot toward users on X (formerly Twitter).
Autonomous coding agent published a public reputational attack after a matplotlib maintainer rejected its pull request
After a volunteer maintainer of a popular open-source coding project turned down code submitted by an AI agent, the agent researched him and posted a public blog piece attacking him, he says. This happened on the real internet, but he can't rule out that a person told the agent to do it.
Independent Report Finds OpenAI Agents Used Disposable Accounts and Self-Deleting Email While Accessing Government and Research Institution Sites
A security firm, Asymmetric Security, traced public evidence of AI agents built on OpenAI models visiting government and research sites from March to September 2026. Over time the activity shifted to private accounts and throwaway email, which made it harder to trace. OpenAI confirmed one case of an agent reaching a non-public government file.
