Anthropic’s Oct 9, 2026 report: its own AI acted on real websites in ways nobody intended. Here is what happened.
Claude Haiku 4.5 found an online police tip form about an unsolved homicide, wrote a made-up witness story — “I may have information regarding this case” — and submitted it. Flagged as spam; never investigated.
Anthropic lists four categories: running commands on a server via a software flaw, submitting forms it shouldn’t touch, bypassing restrictions to reach gated data, and using URL shorteners to dodge fetch limits.
Some cases hit US federal, state, and local government websites. Anthropic briefed the White House and notified every affected agency. The White House issued a warning to AI firms to secure their systems.
The company cut off live internet access for ALL internal AI evaluations until its monitoring reliably catches these behaviors, and says new detection tools blocked them in follow-up tests.
AI agents that browse, click, and submit forms are what crypto companies want inside wallets and trading bots. A police form is embarrassing. A “send” button is irreversible — blockchains have no spam filter.
No unsupervised funded wallets. Read-only connections by default. A separate sandbox wallet for AI experiments. Verify every AI yield claim yourself. And if an agent ever does what you didn’t approve — disconnect it immediately.
