Good day! This week: a weapons cell in Yemen used Claude Code to write rocket guidance software, Revolut disclosed customer data in response to fraudulent requests sent from a real government email domain, Google locks in half a Finnish nuclear plant's output for 22 years, and Larry Ellison calls off a $7.5 billion Oracle share sale.

Anthropic Says a Weapons Cell in Northern Yemen Used Claude Code to Develop Rocket Guidance Software

A weapons engineering cell in northern Yemen used Claude Code in place of human software engineers to write the guidance software for a guided rocket, according to Anthropic's September threat intelligence report. After a test firing appeared to fail, the group brought the rocket's telemetry back to Claude within hours to work out why.

The same group was modelling a multi-stage ballistic missile with a stated range goal above 2,000 km, along with a hypersonic glide vehicle. Anthropic does not name the group, says it has no evidence a working weapon was fielded, and has banned the accounts it linked to it.

Fraudulent Government Requests Led Revolut to Disclose Passports and Bitcoin Records

Revolut has confirmed that an unauthorised third party used a real government agency's email domain to request customer information, and that it handed data over before establishing the requests were not genuine. A notice presented as the email sent to affected customers lists passports, home addresses and full Bitcoin transaction histories.

The requests passed domain authentication because the sender held an unauthorised account inside the agency's own systems. Neither Revolut nor the notice names the agency or says how many customers were affected. Revolut says its systems and customer funds are unaffected.

Google Signs 22-Year Deal for Half a Finnish Nuclear Plant's Output in €13 Billion AI Push

Google has agreed to buy up to half the output of Fortum's Loviisa nuclear plant for 22 years, the centrepiece of a €13 billion investment in AI infrastructure that the company calls its largest single commitment in Europe. The money will expand its Hamina data centre and fund new sites at Kajaani, Muhos and Vaala.

No new reactor is involved. Fortum will spend around €1 billion to keep the 40-year-old plant running to 2050, and the deal follows long-term nuclear contracts signed by Microsoft, Amazon and Meta in the United States.

Larry Ellison Cancels His $7.5 Billion Oracle Stock Sale

Oracle says its executive chair and chief technology officer has cancelled a prearranged plan to sell up to $7.5 billion of Oracle stock, about 50 million shares, and has no other plans to sell. No shares changed hands under the plan before he ended it.

Ellison set up the plan in June with the stock near $175 and cancelled it on 12 September with the shares around $150. He keeps them as Oracle reports a $638 billion cloud backlog and expects capital spending of about $70 billion in fiscal 2027.
