Myth AI is a threat to cybersecurity, but it doesn’t rewrite the rules of the game

The cybersecurity community went on alert when Anthropic announced on April 7, 2026 that its newest and most powerful general-purpose model for large languages, Claude Mythos Preview, had demonstrated remarkable – and unintended – capabilities. The artificial intelligence system was able to find and exploit software vulnerabilities – the most serious type of software bug – at an unprecedented pace.

The news sparked concern among the public, world governments and the information technology sector about the ability of today’s AI to undermine cybersecurity, with some people calling the model a global cybersecurity threat.

Anthropic claimed that it would be too risky to release the model and that the company had a moral responsibility to disclose these vulnerabilities. Anthropic said it would not immediately offer the model to the public. Instead, it gave tech giants exclusive access to test the model’s capabilities, a process Anthropic called “Project Glasswing.”
