US officials weigh cutting deadlines to fix digital flaws amid worries over AI-powered hacking

US cybersecurity officials are considering sharply shorter deadlines for fixing critical flaws in government IT systems, amid concerns hackers could exploit them using artificial‑intelligence tools such as Anthropic’s Mythos, people familiar with the matter said.

The move, which has not been previously reported, would slash the deadline ​for responding to actively exploited vulnerabilities from two weeks to three days, the people said.
