Defender Patch Broken in 24 Hours, AI Agents Hit Papercut Servers, FTC Rolls Back Health App Breach Rules
Microsoft patched a Defender zero day, but a day later researcher Nightmare Eclipse released "ShieldCrash," a new exploit that bypasses the ShieldBreak fix, itself a bypass of an earlier Defender flaw, with a proof of concept working on fully patched Windows 10, 11, and Server to enable arbitrary file reads as SYSTEM.
Researchers also tied recent Papercut print server compromises to a suspected Russian-speaking criminal who used hundreds of AI agents (OpenAI Codex and a DeepSeek model) plus tools like Mimikatz and Impacket to rapidly attack 440 servers across 395 organizations in 48 countries, heavily impacting schools and achieving domain admin in 12 cases.
The FTC rescinded a 2021 policy applying breach notification rules to health apps and connected devices.

Microsoft's Record 966-Fix Patch Tuesday, Liquid Network Bitcoin Returned (Mostly), and Five Eyes' Back-to-Basics Warning
Cybersecurity Today host David Shipley reports Microsoft's largest Patch Tuesday ever with 966 vulnerability fixes (plus 204 earlier cloud-service fixes), including 105 critical issues, two actively exploited Windows zero-days, and a surge tied to AI-assisted bug discovery—raising defenders' triage and testing burden. 
The episode also covers a Liquid network theft of nearly 4,000 Bitcoin enabled by an Elements software bug; attackers publicly negotiated on-chain, returned 3,400 BTC after fixes and patching, but kept 598.5 BTC, prompting debate over "white hat" claims versus extortion or laundering. 
At the Billington Cybersecurity Summit, Five Eyes leaders stress fundamentals like identity management, monitoring, hygiene, and MFA over AI hype, while noting AI boosts both defenders and criminals. 
Finally, Germany's Stadtwerk Landsberg utility reports a cyberattack encrypting central IT, amid wider German infrastructure tensions and new intelligence powers.

Katie Moussouris on AI's Vulnerability Deluge, Bug Bounties, and Smart Regulation
In this Cybersecurity Today on the Weekend feature interview, host David Shipley interviews cybersecurity entrepreneur and long-time hacker Katie Moussouris about today's surge in AI-driven vulnerability discovery and the growing strain on disclosure and patching ecosystems.
Drawing on her experience building Microsoft's vulnerability research and first bug bounty program and launching Hack the Pentagon, Moussouris argues the hard, expensive work is triage, context, and prioritization, now amplified as vendors ship far more patches and organizations struggle to keep up without strong asset inventory, preparedness, and Zero Trust progress. 
She warns AI model capabilities are outpacing monitoring and containment, especially with open-weight models, and says regulation should focus on requirements like real-time monitoring without harming defenders.
The conversation also covers the reemergence of the old tool-access debates, Microsoft's clash with researcher "Nightmare Eclipse," the rise-and-fall of "security civilizations," Luta Security's work improving internal maturity, concerns about shrinking entry-level talent pipelines, and a closing call to consider universal basic income as part of our strategy to deal with AI's impact on the world.

153M Driver's Licenses for Sale, 9.5M-Patient Breach, and CISA Drops Key Security Assessments
The episode reports the FBI investigating Nexus, a dark web service selling scans of over 153 million U.S. and Canadian driver's licenses and other identity documents, with evidence suggesting near real-time exfiltration tied to IDscan.net before Nexus abruptly disappeared.
It also covers a breach at healthcare SaaS provider Aesto Health affecting 9.54 million individuals, exposing extensive personal and medical data, with delayed confirmation and notifications and 24 months of Experian monitoring offered.
The show details CISA ending six free critical-infrastructure cybersecurity assessments amid workforce reductions, raising concerns given recent targeting of U.S. water systems and warnings about AI-generated exploitation scripts against Siemens PLCs.
Additional updates include Plex urging immediate patching of undisclosed vulnerabilities and Slovenia's HIT gradually reopening casinos after a cyberattack forced a three-day shutdown.
