Mythos AI Highlights Existing Cybersecurity Vulnerabilities Without Changing the Fundamental Threat Landscape

In April 2026, Anthropic unveiled Claude Mythos Preview, a highly capable AI model able to detect and exploit software vulnerabilities at unprecedented speed. During controlled evaluations, the AI identified hundreds of vulnerabilities in widely used software such as Mozilla Firefox and OpenBSD, developing exploits for many of them. Notably, inexperienced engineers were able to complete multistep attacks overnight, tasks that normally require weeks of expert effort. Despite these impressive capabilities, experts emphasize that Mythos does not introduce fundamentally new threats. Most vulnerabilities it identified are well-known types, and its strength lies in automation and rapid chaining of standard cybersecurity procedures. The AI's performance exposes the limitations of current vulnerability detection practices rather than creating unknown risks. Mythos also underscores a persistent cybersecurity reality: defenders must always succeed, while attackers need only succeed once. Tools l
