Anthropic’s Mythos Model Forces Companies to Regroup for a New Cyber Era

Anthropic’s recent disclosure of an AI bug‑finding model deemed too “dangerous” for public release is forcing companies to rethink their cybersecurity programs and operations. Instead of releasing the model broadly, the company has convened a closed group of industry leaders across cloud infrastructure, operating systems, networking and finance to deploy its Claude Mythos Preview model in controlled testing of critical software. A week after Anthropic’s announcement, OpenAI likewise revealed it had provided a select group access to its own unreleased model for cyber testing and remediation. As AI accelerates vulnerability discovery and exploits, the Cybersecurity Law Report discussed the implications with legal and cybersecurity leaders from Akin, Alston & Bird, A&O Shearman, Cloud Security Alliance, Cyber Threat Alliance, Debevoise and Paul Weiss. This article examines how Mythos-class models may alter expectations for cyber programs and create pressure on existing vulnerability-sharing frameworks. It also outlines concrete steps CISOs, GCs and boards should consider as AI compresses vulnerability discovery and exploitation timelines. See our two-part series on AI agent security: “Companies See Rogue Incidents but Lag on Controls” (Mar. 18, 2026), and “What CISOs and GCs Need to Know to Defend the Enterprise” (Mar. 25, 2026).

Connected Cars: Addressing Cybersecurity Issues

The connectedness of today’s cars to the broader digital ecosystem introduces cybersecurity risks that original equipment manufacturers must identify and address. These risks include not only a data breach that could expose the intimate details of an individual’s life but, even more critically, threats to the physical safety of a vehicle’s occupants. This final article in a four-part series on connected cars provides an overview of the legal regime governing vehicle cybersecurity, examines potential vulnerabilities, and offers best practices for implementing a cybersecurity and incident response framework, with insights from experts at Exponent, McDermott, Will & Schulte and Morrison Foerster. Part one covered FTC enforcement activity related to connected vehicles, part two discussed the legal framework and part three examined privacy compliance issues.

How Tech CLOs Think Attorneys Should Be Using AI

AI is fundamentally changing the practice of law, but many attorneys are confused or even frightened about what the technology may mean for their careers. Legal tech tools have evolved from basic spelling and grammar checks to document review and drafting, and now include sophisticated AI agents capable of handling complex tasks independently. Chief legal officers at technology companies are uniquely situated to see both sides of this evolution as they serve as the nexus between their business partners and outside counsel. This article summarizes key takeaways from a recent panel of lead counsel at Google, Anthropic, Liberty Mutual and IBM, who spoke at the ABA White Collar Crime Institute regarding how lawyers can adapt and thrive during this continuing wave of change. See “Benchmarking AI Uptake by Compliance Functions” (Dec. 3, 2025).
