Anthropic PBC\u2019s Claude Mythos model has emerged as the most widely discussed artificial intelligence solution without being fully released.<\/p>\n

Information about the model, which\u00a0reportedly\u00a0has the ability to analyze software at large scale, find bugs in hardened software ecosystems, and identify vulnerabilities, has been tightly controlled by Anthropic. That situation did not change much on Monday when Anthropic Head of Threat Intelligence\u00a0Jacob Klein\u00a0(pictured) spoke at the\u00a0SANS Cybersecurity Summit\u00a0in a hotel just outside of Washington D.C., although he did provide a hint of the model\u2019s capabilities during his appearance.<\/p>\n

Klein offered a brief description of the model\u2019s power in the context of how rapidly AI has changed the cybersecurity world and vowed transparency in the months ahead.<\/p>\n

\u201cIt\u2019s very good at finding vulnerabilities and chaining them together for an exploit,\u201d Klein told the group. \u201cYou have to rethink what your risk picture looks like now. The landscape has changed today. There is a trade-off that we have to balance out. We will be transparent, and I would hope that the other labs will have the same level of visibility.\u201d<\/p>\n

Breaches are accelerating<\/h3>\n

Klein\u2019s appearance at the SANS Institute\u2019s gathering comes at a time when the pace of AI-related breaches has picked up dramatically. Over the past weekend, cloud development platform Vercel Inc. disclosed that its internal systems had been breached through a compromise of Context.ai, a third-party tool used by a Vercel employee.<\/p>\n

Hackers have since claimed to have stolen customer credentials from Vercel and have made the data available for sale online. This followed a report earlier this month that a North Korean threat actor inserted malicious code into the widely used Java script library Axios, as adversaries have used AI to probe every link in the supply chain.<\/p>\n
