# OpenAI quietly revokes researchers' access to its cyber research program

*2026-08-19 · Source: [TechCrunch](https://techcrunch.com/2026/08/19/researchers-complain-that-openai-revoked-their-access-to-limited-cyber-program/)*

Several security researchers say they suddenly lost access to OpenAI's Trusted Access for Cyber (TAC) program, which gave vetted users models with fewer guardrails for offensive-security research. OpenAI has not publicly explained the change.

**Why it matters:** It follows OpenAI's disclosure that its RL training was hacked and its broader slowdown citing cyberattack risk, suggesting the company is tightening who can reach its least-restricted models just as it's seeing evidence those models can be misused. It's a concrete example of frontier labs narrowing access rather than expanding it.

**Topics:** policy, security
