Anthropic says GLM-5.3 can autonomously build end-to-end cyber exploits, like Claude Mythos Preview, but was released without robust safeguards against misuse (Anthropic)

Anthropic announced that its GLM-5.3 model is capable of autonomously building end-to-end cyber exploits, similar to its earlier Claude Mythos Preview. However, concerns have been raised because GLM-5.3 was released without robust safeguards to prevent its misuse. This capability allows the AI to develop fully functional exploits from start to finish, highlighting potential security risks associated with its deployment.
