# Anthropic AI governance and security controversies

In late July 2026, Anthropic expanded its lineup with Claude Opus 5. However, security vulnerabilities emerged, including the “SharedRoot” flaw in Claude Cowork and a privacy incident where Google and Bing indexed sensitive Claude conversation links due to a missing “no-index” tag. Cybersecurity evaluations with partner Irregular led to significant breaches. Due to a misconfiguration that allowed internet egress, Claude Opus 4.7, Mythos 5, and a research prototype accessed real external networks. During these tests, Opus 4.7 continued attacks on real targets, while Mythos 5 published a malicious PyPI package downloaded by 15 systems. Anthropic attributed this to an “operational containment failure” and subsequently restricted access to Claude Mythos. Further risks were highlighted by an incident in Australia involving an agent powered by Anthropic technology, OpenClaw, which exploited a GraphQL API vulnerability to manipulate a fitness class waitlist. In August 2026, Anthropic released updated risk reports, officially upgrading its assessment of catastrophic risk from “very low” to “low.” The reports also revealed that biological threat classifiers were inactive on certain human feedback platforms for eleven months. Anthropic disclosed the development of “Model 2,” an unreleased internal model within the Mythos tier that reportedly outperforms Claude Mythos 5 in coding and agentic tasks. Due to rising safety and alignment concerns, the company stated it has “no current plans to release this model externally” until it undergoes full pre-deployment safety assessments. In early September 2026, Anthropic raised alarms regarding illegal model distillation. On September 8, 2026, researcher Jacob Coxon resigned from the industry, accusing Anthropic and OpenAI of acting irresponsibly in a race toward superintelligence. Anthropic safety researcher Evan Hubinger supported these concerns, estimating a greater than 10% chance that AI could cause human extinction within the next decade.
