There\u2019s just one problem: Anthropic launched the initiative only because, during testing, it discovered that Claude Mythos Preview was surprisingly good at hacking software. Anthropic didn\u2019t develop Claude Mythos Preview to hack software, either. It just turned out to be shockingly good at it.<\/p>\n
That\u2019s also why Anthropic isn\u2019t releasing the Claude Mythos Preview to the public. The company needs to develop cybersecurity safeguards to \u201cblock the model\u2019s most dangerous outputs.\u201d<\/p>\n
Now, the company is working with partners including Amazon (AMZN<\/a>), Apple (AAPL<\/a>), Microsoft (MSFT<\/a>), and Nvidia (NVDA<\/a>) through Project Glasswing to help them identify vulnerabilities in their software before similarly powerful models hit the market.<\/p>\n Claude Mythos Preview, Anthropic says, has already discovered thousands of flaws in existing programs and applications, including all of the popular operating systems and web browsers.<\/p>\n In one particular example of the model\u2019s abilities, Anthropic said Mythos was able to chain together several software vulnerabilities in Linux. This popular operating system underpins much of the web and enables ordinary users to gain complete control of a computer.<\/p>\n It\u2019s not just cutting-edge models like Mythos that represent a potential cybersecurity threat, though. According to experts, the industry\u2019s move toward AI generally represents a new opportunity for hackers to breach systems worldwide.<\/p>\n \u201cThe level of opening that this provides attackers is dramatic,\u201d Charles Harry, a research professor at the University of Maryland who leads the Center for Governance of Technology and Systems<\/a>, told Yahoo Finance.<\/p>\n The good news? The same technologies can be used to prevent cyberattacks as long as defenders can catch up.<\/p>\n Hackers have existed for decades, finding and exploiting software errors to steal data, take control of systems, and more.<\/p>\n Humans are, well, only human, and when they write code, they occasionally make mistakes. Despite strenuous testing, those errors get overlooked and eventually ship with the final piece of software. Hackers spend their time scouring programs and applications for bugs in the hopes of using them to break into a piece of software. And tossing AI into the mix only further complicates things.<\/p>\n \u201cAI is just yet another layer of complexity on an already complex technical ecosystem,\u201d Harry said. Attackers can exploit that complexity by finding more ways into software.<\/p>\n Andrew Lohn, a senior fellow at Georgetown University\u2019s Center for Security and Emerging Technology (CSET), said that AI coding isn\u2019t helping either.<\/p>\n \u201cOne thing that I worry about a little bit with AI, and [large language models] in general, is you can produce more code \u2026 so there\u2019s more vulnerabilities,\u201d he told Yahoo Finance.<\/p>\n \u201cAs more code gets written by AI, and more of the code gets inspected or certified by AI, then it raises more questions about where the vulnerabilities are,\u201d Lohn said.<\/p>\n The massive push across the tech industry to take advantage of AI as quickly as possible could prompt some workers to cut corners, potentially exposing more companies to cyberattacks.<\/p>\n We\u2019ve already seen it on the offensive side. Security researcher Callum McMahon discovered a piece of malware that ricocheted from an open-source project called LightLLM to an AI training company, Mercor, last month.<\/p>\n That in and of itself isn\u2019t Earth-shattering. But according to TechCrunch<\/a>, McMahon<\/a> and AI researcher Andrej Karpathy<\/a> found that the malware was \u201cvibe coded,\u201d meaning the attacker created it using AI. The reason McMahon found it? The malware itself contained an error that crashed his computer.<\/p>\n And if those errors are happening on the offensive side, they\u2019re certainly happening on the defensive side.<\/p>\n Anthropic also suffered a cybersecurity incident last week, though the company said the leak of some of its source code was the result of human error, not a cyberattack. Still, Lohn said the push to go faster makes similar instances more likely.<\/p>\n It\u2019s not all negative news, though. Just as AI can be used to attack different pieces of software, it can be used to defend against attacks as well. Companies across the spectrum are implementing AI into their cybersecurity systems to detect attacks early and address them promptly.<\/p>\n Harry, however, cautioned that as organizations lean further into AI defense, malicious actors will look for increasingly clever ways to hide their attacks. And the fighting will continue.<\/p>\n Email Daniel Howley at dhowley@yahoofinance.com.
