S4E20 - AI Executive Order, Project Glasswing Expanding, Cybersecurity Workforce

Promoting Advanced Artificial Intelligence Innovation and Security The White House EO pushes federal agencies toward AI-enabled cyber defense, frontier-model benchmarking, and a voluntary framework for trusted access to high-end AI systems. Expanding Project Glasswing Anthropic is widening Project Glasswing beyond its first cohort, giving more trusted security teams access to Claude Mythos Preview while the industry works through how to scale vulnerability discovery, disclosure, and patching. Securely testing on customer data The crew digs into the practical problem of validating AI and security tools against real customer environments without turning sensitive data into test exhaust, training material, or cross-tenant risk. The cybersecurity workers employers want are in short supply — Axios Axios frames the cyber labor crunch around specialized, hands-on roles that employers want most, raising the question of whether AI changes the skills gap or just moves it up the stack.

S4E14 – Federal Gov vs. Anthropic, 40% layoff at Blocks due to AI

Claude Code Security research preview Claude now reasons about code like a human researcher, re-checks its own findings for confidence, and surfaces patch suggestions in a dashboard while keeping humans in control—limited preview for Enterprise/Team customers plus expedited access for open-source maintainers. Pentagon gives Anthropic a best-and-final offer With a deadline looming, the Pentagon demanded full lawful-use access, threatening supply-chain risk and even a Defense Production Act push, but Anthropic stood firm on guardrails around mass surveillance and autonomous weapons. State Department and other agencies ditch Anthropic for OpenAI State, Treasury, HHS, and others are dropping Claude after Trump’s directive to cancel Anthropic contracts, swapping in OpenAI’s GPT-4.1 for tools like StateChat as the broader federal boycott takes shape. New AirSnitch attack bypasses Wi-Fi encryption AirSnitch leverages cross-layer identity desync to nullify client isolation on routers from Netgear to Cisco, giving nearby attackers full MitM access to intercept and tamper with otherwise encrypted traffic. Your password manager’s “zero knowledge” promise is broken ETH Zürich’s USENIX paper proves that malicious servers controlling Bitwarden/Dashlane/LastPass infrastructure can hijack everyday vault interactions and read users’ encrypted data despite the “zero knowledge” pitch. Researchers find critical vulnerabilities in cloud-based password managers The ETH team demonstrated a dozen attacks on Bitwarden, seven on LastPass, six on Dashlane, and even a 1Password flaw, showing compromised servers—without exotic hardware—can view or rewrite entire vaults.

Adversarial Podcast S4E12 – Curl shuts down bug bounty program, most expensive security control that gave zero security

The end of the curl bug bounty program. Curl’s creator Daniel Stenberg announced the shutdown of the project’s bug-bounty program because overwhelming volumes of low-quality and AI-generated reports, coupled with bad-faith security submissions, impose excessive mental and time costs while providing little real improvement to the software.Changing Federal Reserve Regulations. The memo directs Federal Reserve supervisory staff to shift toward a more risk-focused, judgment-driven, and proportionate supervisory model that prioritizes material financial risks, relies more on other regulators’ and firms’ internal audit work, reduces procedural and duplicative oversight, and sharpens the clarity and impact of supervisory findings and enforcement.Reddit: "What is the most expensive security control you added that gave zero security."

00:00 Intro 01:40 Iran's Internet blackout 48:06 U.S. Weighs Expanding Private Companies’ Role in Cyberwarfare 57:35 Aligning cybersecurity programs to frameworksThere's an internet blackout in Iran. How are videos and images getting out? During Iran’s nationwide internet blackout imposed amid widespread anti-government protests, some citizens have been using Elon Musk’s Starlink satellite service to bypass state-controlled communication blackouts and share information with the outside world despite government efforts to restrict or jam such access.Lawmakers to Restart Efforts to Revive Lapsed Cyber Intel Bill. U.S. lawmakers are preparing to revive and reauthorize the lapsed Cybersecurity Information Sharing Act, a key bill that facilitates sharing of cyber threat intelligence between the federal government and the private sector, with bipartisan momentum to include it in broader funding legislation as concerns grow about rising cyber threats and gaps left by the law’s expiration.U.S. Weighs Expanding Private Companies’ Role in Cyberwarfare. The U.S. administration is considering a significant shift in cyber strategy that would allow private companies, beyond their current contractor roles, to directly participate in offensive cyber operations against foreign adversaries—a move that would require new legal authorities and raises legal, ethical and oversight concerns.Should Our Security Controls Be More Like North Korea or Norway? Security programs work better when they resemble Norway’s balanced, trust-based model rather than North Korea’s heavy-handed, surveillance-first approach.Hosts:Jerry Perullo (Founder, https://adversarial.com/)Sounil Yu (Founder, https://www.knostic.ai/)Mario Duarte (Founder, stealth startup)Producer: Tillson Galloway (Founder, http://githoundexplore.com/)
