Anthropic's new Mythos Preview model could significantly enhance security for under-resourced critical infrastructure sectors, such as water systems and gas suppliers, who have struggled to update their technology stacks. The U.S. government is involved in a significant dispute with Anthropic, which has found serious security flaws in nearly every operating system during testing. The government has also cut resources at the Cybersecurity and Infrastructure Security Agency (CISA), which would lead these efforts. However, the Trump administration has reduced the agency's funding, staffing and resources and has proposed more cuts next year. The administration's nominee to run CISA has been in limbo in the Senate for more than a year.
