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.

22,000 Exchange Servers Exposed, 700 AI Agents Swarm Hugging Face, and FSB Warns Frontier AI Is Top Financial Risk

Cybersecurity Today with host David Shipley reports nearly 21,899 Microsoft Exchange servers still exposed and unpatched for high-severity auth-bypass CVE-2026-62911, enabling mailbox takeover, with exploit code circulating and Germany warning most on-prem Exchange remains vulnerable as support deadlines loom.
The U.S. DOJ also corrected a press release to say multiple U.S. agencies were targeted—not confirmed victims—by China-linked QTFY intrusions.
Postmortems on the OpenAI/Hugging Face incident describe roughly 700 agents coordinating via shared notes and messaging to exploit systems, steal tokens and credentials, execute commands, and compromise infrastructure before Hugging Face shut it down July 13.
Palo Alto Unit 42 warns AI-driven exploitation is arriving, citing a case where AI leveraged 50 vulnerabilities in 10 hours. The Financial Stability Board calls frontier-AI cyber risk the most immediate threat to global finance and urges stronger safeguards and recovery planning.

Shiny Hunters Claims 284M McKesson Records Stolen, PaperCut Patch Bypassed Again, and White House Bans Foreign Power Grid Tech
 
Host David Shipley covers multiple cybersecurity headlines: Shiny Hunters claims it breached healthcare giant McKesson via voice phishing, compromised Okta SSO, and accessed Salesforce and Snowflake, allegedly exfiltrating about 1TB and 284 million patient records (records, not unique patients) and demanding a $55M+ ransom, though the claims aren't independently verified. PaperCut issued a second emergency patch after bypasses were found for fixes to two actively exploited vulnerabilities that can be chained for unauthenticated remote code execution; organizations on v23 or earlier must upgrade. Berlin confirms an extortion attempt tied to Rhysida, which claims 5.79TB stolen. WordPress discloses five critical plugin/theme flaws enabling full site takeover, including a 10/10 GiveWP RCE. The White House bans foreign-made bulk power grid equipment over backdoor concerns amid rising critical-infrastructure attacks.

Varonis AI Threat Lead on Copilot Exploits, Prompt Injection, and the AI Hacking Trifecta
The host interviews Mark Vaitsman, AI threat research lead at Varonis, about Varonis Threat Labs' research into AI vulnerabilities, including a chain of single-click exploits in Microsoft Copilot (including "CoSnitch") and an Atlassian Confluence issue dubbed "RovoBlast" involving prompt injection, bypassing guardrails, and data exfiltration via a web-capable subagent.
Vaitsman explains why built-in model guardrails are insufficient, citing AI's lack of loyalty and "unlimited hunger for data," and argues for layered controls like least privilege, monitoring, and restricting data access.
He discusses psychological guardrail bypasses, introduces an "AI Hacking Trifecta" framework—enter, evade, escape—and comments on research showing AI-generated patches often fail, emphasizing human-led validation and guidance when using AI tools for security research.
