The images appear tied to Louisiana-based IDScan.net, which provides identity verification to retailers, rental-car companies, and others. KrebsOnSecurity matched some records to licenses scanned during Hertz rentals. IDScan says it's investigating and hasn't determined the breach's nature or scope.

Under new Enterprise Frontier Safeguards, customers can keep data in their own cloud and block Anthropic employees from reviewing it while automated abuse monitoring continues. Anthropic calls that privacy equivalent to zero data retention. Developed with more than 100 customers, including Salesforce, the system is due later this year. (CNBC) Astra enters OpenAI's cyber red zone OpenAI says Astra is its first model to reach a "Critical" cybersecurity threshold, meaning it can find unknown flaws and build exploits across well-defended systems without step-by-step human help. It's due soon, but the advanced cyber capabilities will start with a small test group before expanding through Daybreak Blue. OpenAI says Astra refused 91.5% of cyber jailbreak requests, versus 59% for GPT-5.6 Sol, and monitoring can pause suspicious activity. The Information reports Astra's latent reasoning may hide parts of its process, raising doubts about chain-of-thought monitoring.

Claude sessions get hijacked Anthropic is warning that common infostealer malware is stealing active Claude browser sessions, letting attackers get into accounts and burn through paid usage without needing a password or two-factor code. The company is signing affected users out, removing stored payment methods and refunding unauthorized charges. But revoking the session doesn't remove the malware, so victims still need to clean the device, change credentials and revoke other active sessions. (BleepingComputer) AI could jolt global finance Bank of England governor Andrew Bailey is warning G20 officials that frontier AI could destabilize the global financial system by making cyberattacks faster, cheaper and easier to scale across borders. Bailey says many countries still lack protocols for how advanced models are developed and released. He also warned that a successful attack on a small number of heavily used technology providers could undermine confidence across the entire system.
