The Department of Know: Liquid drained, CISA urges change, agentic whistleblowers
Read the full stories at CISOSeries.com This week's Department of Know is hosted by Rich Stroffolino, with guests Alexandra Landegger, global head of cyber strategy & transformation, RTX, Mark Eggleston, CISO-at-large. Missed the live show? Check it out on YouTube. The Department of Know is live every Friday at 4:00 p.m. ET. Join us each week by registering for the open discussion at CISOSeries.com. Big thanks to our sponsor, ThreatLocker This week, we looked at how AI is making attacks faster, less predictable, and easier to execute. But an AI-generated attack still needs permission to run, access data, use trusted applications, and move through the environment. ThreatLocker helps organizations control those actions before they become incidents. Book a demo at threatlocker.com/ciso.

153M licenses for sale, Anthropic reverses course, Astra enters the red zone
Dark web shop stocks 153 million driver's licenses Nexus, a new dark web service, claims it's selling scans of more than 153 million US and Canadian driver's licenses, plus over 10 million ID cards, three million travel and international IDs, and at least 579,000 medical cards. 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. The FBI's New Orleans office has opened an inquiry. (KrebsOnSecurity) Anthropic puts 30-day data retention in reverse After customer pushback, Anthropic is revising a policy that stored 30 days of traffic from its Fable and Mythos models. 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 hijacked, AI jolts global finance, agents get too many keys
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. (The Guardian) AI agents get too many keys New research from Cequence Security and Enterprise Management Associates found a sizable confidence gap around AI agent permissions. 94% of surveyed organizations believe their agents don't have more access than necessary, but only 33% actually enforce least privilege. 65% have seen an agent act outside its intended role, and 29% say that caused measurable business impact.
