Using an unordered list, summarize the following article with between 4 and 8 key points.
\nOperational technology providers and their industry groups have been pressing for access to Anthropic\u2019s cybersecurity-focused Mythos Preview model, arguing the initial rollout \u2014 which focused on major tech and finance firms under a global vulnerability patching effort \u2014 left out a widely exposed segment of critical infrastructure that\u2019s often targeted by hackers.In recent weeks, OT industry representatives\u00a0have expressed frustration\u00a0during roundtables and listening sessions about their initial exclusion from Project Glasswing, Anthropic\u2019s initiative with major companies designed to secure critical software across the globe using the Mythos model, according to four people familiar with the discussions.\u00a0The processes for these firms to be granted access are ongoing, two of the people said. All of the sources requested anonymity because the discussions are private.American Water, one of the nation\u2019s largest regulated U.S. water and wastewater utilities, is among several organizations that have recently met with the Office of the National Cyber Director to discuss Mythos and broader AI-cybersecurity threats, said one of the people. American Water heavily relies on and oversees complex operational technology systems to manage its water treatment and distribution infrastructure.\u00a0\u201cThere\u2019s definitely an annoyance in the OT world,\u201d that person said. \u201cThat doesn\u2019t mean people aren\u2019t considering the needs of OT,\u201d they noted, but decisionmakers dictating initial Glasswing access \u201cweren\u2019t thinking in those terms.\u201dNextgov\/FCW has asked Anthropic, ONCD and American Water for comment.Operational technology, which is embedded in critical infrastructure everywhere, is a constant point of concern for cyberdefenders because it underpins essential everyday services like energy, water and transportation. Disruptions to those systems can have immediate real-world consequences.Amid the U.S.-Israel war against Iran, Tehran-backed hackers exploited and disrupted operational technology control systems embedded in multiple U.S. critical infrastructure sectors, targeting equipment manufactured by Rockwell Automation, according to a government advisory issued last month.DARPA recently concluded a two-year-long competition where teams built AI models to autonomously identify and patch vulnerabilities in open-source code used in critical infrastructure systems. Many major AI firms, including Anthropic and OpenAI, provided model infrastructure to participants.Even when access is granted to Mythos, that doesn\u2019t automatically mean all vulnerabilities in a network are fixed, said Cynthia Kaiser, a former senior FBI cybersecurity official, adding that firms will have to prioritize what to patch once they can test their infrastructure against the model.\u201cIt\u2019s not just about getting access. People need to think about \u2014 when they get it, where do they start?\u201d said Kaiser, now senior vice president at Halcyon\u2019s Ransomware Research Center.\u00a0Physical operational systems are often harder to patch than IT because they usually can\u2019t be easily taken offline to apply fixes, and they rely on aging, vendor-controlled equipment that makes rapid patching difficult.Regardless, \u201cthe fact that boards and CEOs have been asking about this \u2014 and that the requests aren\u2019t coming from [Chief Information Security Officers] \u2014 shows that the release of Mythos means companies are taking cybersecurity more seriously,\u201d she added. \u201cI think it\u2019s good and important that they\u2019re thinking about this now.\u201dMythos has been deemed a major turning point for cybersecurity and AI practitioners because it demonstrates how advanced models can be purpose-built for real-world cyber operations, including those planned inside the intelligence community. In the wrong hands, it could be used to carry out sophisticated cyberattacks against government networks, critical infrastructure or other key U.S. systems.The Pentagon labeled Anthropic a supply chain risk earlier this year \u2014 and the White House later ordered a governmentwide phaseout of its technology \u2014 after the AI company declined to ease restrictions on its products being used in domestic surveillance and fully autonomous weapons.The company has legally challenged the supply chain risk label. A federal judge issued a temporary injunction on the designation and ban in late March, which the government has said it intends to appeal.<\/p>\n
