Treasury’s Scott Bessent says no liability exemptions for AI labs
Treasury Secretary Scott Bessent urged Congress to reject AI labs' requested liability exemptions, arguing creator liability is the best safety guarantee.
Testifying before the House Financial Services Committee, Treasury Secretary Scott Bessent said the government should not grant frontier labs liability waivers, responding to Anthropic CEO Dario Amodei's slowdown essay. He cited Treasury's AI safety work since the release of Anthropic's Mythos model, whose cybersecurity risks prompted an April meeting, and coordination with banks and labs after the July Hugging Face cyberattack. Bessent also highlighted the Gold Eagle clearinghouse run with CISA and called for more US-built open-source models to counter China.

25 Years of Mass Surveillance Is Enough
Bruce Schneier and Cindy Cohn argue post-9/11 mass surveillance expanded far beyond its counterterrorism justification and should be reevaluated for costs to rights.
An essay by Bruce Schneier and Cindy Cohn (originally in Lawfare) traces the post-9/11 shift from targeted surveillance to mass collection of telephone and internet metadata. It cites the Section 215 bulk phone records program, struck down in interpretation by the Second Circuit in 2015 and curtailed by the USA Freedom Act, and the NSA's Upstream program under Section 702 of the 2008 FISA Amendments Act, which ended content searches in 2017. The authors note mass surveillance now serves routine law enforcement and immigration actions, with FBI Director Kash Patel confirming purchases of Americans' data from brokers, and private systems like Flock license plate readers and venue facial recognition feeding government access.

Risky Bulletin: Ukraine's top prosecutor resigns amid scam call center scandal
Ukraine's top prosecutor Ruslan Kravchenko resigned after NABU arrested a deputy for taking bribes protecting scam call centers running fake investment platforms.
Ukraine's anti-corruption bureau NABU arrested Serhiy Kropyva, Deputy Head of International Cooperation at the Prosecutor General's Office, alleging officials took monthly protection fees from a network of 100-500 scam call centers luring victims into fake investment platforms, with bribes reportedly growing from $700,000 to $3.5 million per month. Prosecutor General Ruslan Kravchenko resigned on Monday, calling it a political decision, while Kropyva was fired with bail set at 120 million hryvnias ($2.7 million) and over 100 call centers shut down in the past month. The newsletter also briefly covers a cyberattack crippling more than 80 Luxembourg medical practices via payment vendor BMS Engineering, ShinyHunters' claimed theft of 200,000 Florida DMV driver records, a cyberattack on the American Meteor Society, and school closures in Springfield, Massachusetts.

Proofpoint 2026 Voice of the CISO Report Finds Cyber Resilience Improving, While AI Expands the CISO Mandate
Proofpoint's 2026 survey of 1,600 CISOs finds improving cyber resilience, rising human risk, and expanding AI responsibilities without added resources.
Proofpoint released its 2026 Voice of the CISO report, a Censuswide-conducted survey of 1,600 CISOs across 16 countries fielded in May 2026. Expected material cyberattacks fell from 76% to 61% year over year and material data loss declined from 66% to 53%, but 79% of CISOs now identify human risk as their biggest vulnerability and GenAI security concerns jumped 18 points to 78%. The report also finds 79% of CISOs expect to manage AI-related risks without proportional resources, and 85% say boards are evaluating cyber risk through a commercial lens.

“Zero-click” WeChat worm could hijack accounts and spread via a single call
Researchers discovered a critical memory corruption flaw in WeChat's VoIP stack enabling a zero-click worm, WeWorm, that hijacks accounts via calls; Tencent patched it.
Calif researchers weaponized a memory corruption issue in WeChat's VoIP stack into "WeWorm", a worm that spreads through WeChat calls without user interaction, hijacks each victim's account, and propagates via saved contacts across iOS and Android, potentially reaching millions of devices within hours. Exploitation takes seconds and grants full account control, and chaining with other reported Android/iOS bugs could lead to full device control. Tencent issued updated WeChat versions for iOS and Android and applied server-side mitigations; technical details remain withheld. WeChat has over a billion users, overwhelmingly in China.

Whistleblower says USPS deploying new, ‘untested’ IT systems governing mail
A whistleblower alleges USPS is rushing untested IT systems that could reject thousands of mail-in ballots ahead of the 2026 midterm elections.
A whistleblower complaint released by Sen. Richard Blumenthal says USPS is deploying three new, largely untested IT systems — including the Federal Ballot Mail Portal — that could reject entire ballot batches over single scan errors. The systems were developed in weeks without standard testing or interoperability checks, and USPS allegedly continued work despite court injunctions against its rule changes. House Oversight Democrats demanded USPS halt implementation, and election experts warn the design could lead to new lawsuits and mass ballot denials.

The AI Kill Switch Act is repeating the Clipper Chip’s mistakes
Op-ed argues the AI Kill Switch Act repeats the Clipper Chip's mistake by mandating backdoors into frontier AI systems.
The op-ed criticizes the AI Kill Switch Act, sponsored by Reps. Ted Lieu and Nathaniel Moran, which would let CISA require frontier AI labs to build the ability to throttle, suspend, or shut down their systems. The author compares this to the 1993 Clipper Chip, whose Law Enforcement Access Field was found flawed in 1994, and argues mandated kill switches would create deliberate weaknesses in AI agents embedded in banking, power grids and other critical infrastructure. It also flags the bill's exemption of red-teaming incidents and CAISI's incomplete agent security standards, recommending mandatory red-teaming and liability frameworks instead.

The push to designate AI as the next critical infrastructure sector
Americans for Responsible Innovation report urges designating AI models, companies and supporting infrastructure as critical infrastructure with CISA as sector lead.
A report from the nonprofit Americans for Responsible Innovation calls for the federal government to declare the AI sector — including frontier model designs, model weights, datacenters, AI hardware and semiconductors — the 17th critical infrastructure sector, with CISA as the lead agency for sector cyberthreats. The authors argue AI is concentrated among a handful of foundation models and interdependent with other sectors, so a single attack on the AI stack could cascade widely, citing incidents like Iranian drone attacks on Amazon datacenters. Former DHS officials note the designation would unlock federal resources such as CDM access and threat intelligence, but warn that picking a lead agency could trigger a bureaucratic turf war with Commerce and Treasury.
