The US government blocked access to Anthropic's Fable 5 and Mythos 5 models due to a 'Fix this code' prompt, which a researcher claims was a routine cybersecurity task, not a jailbreak. Anthropic disabled the models to comply, and cybersecurity experts argue the restrictions hinder defensive capabilities.

The U.S. government imposed export controls on Anthropic’s Fable 5 and Mythos 5 AI models after Amazon researchers discovered a security vulnerability triggered by the phrase 'fix this code,' enabling the models to generate exploitable security patches. Anthropic disabled the models for all users to comply with export regulations affecting non-citizen access.

Amazon alerted the White House about security risks in Anthropic's Fable 5 AI model, leading to a government-imposed takedown. The model was shut down after Amazon's report on jailbreaking vulnerabilities, despite Anthropic's prior notifications to the government.

The U.S. government ordered Anthropic to suspend foreign access to its AI models Fable 5 and Mythos 5 over national security concerns related to a potential jailbreak method. Anthropic disabled the models to comply, citing disputes over the severity of the reported vulnerability and noting similar capabilities exist in other public models.

The U.S. Commerce Department imposed export restrictions on Anthropic’s Fable 5 and Mythos 5 AI models after research revealed potential bypassing of safeguards. Anthropic disputes the restrictions, arguing they could hinder AI development, while cybersecurity expert Katie Moussouris claims the research was defense-oriented, not malicious.

Microsoft threatened criminal legal action against security researcher 'Nightmare Eclipse' for publicly disclosing zero-day vulnerabilities without prior coordination. The researcher claimed Microsoft refused to communicate, deleted their security response account, and flagged their GitHub account, escalating a public dispute over vulnerability disclosure practices.

Microsoft softened its stance after initially threatening legal action against researcher Nightmare-Eclipse for publicly disclosing Windows zero-day vulnerabilities. The researcher released exploit code, prompting Microsoft to face backlash from the security community. Microsoft's updated statement emphasized no legal pursuit against security researchers but stopped short of addressing specific allegations.
