American AI developer Anthropic said Tuesday it was investigating unauthorized access to Mythos, its powerful model which the company itself worries could be a boon for hackers.<\/p>\n
Anthropic said earlier this month it restricted\u00a0the release of Mythos\u00a0to 40 major tech firms to give them a head start in fixing cybersecurity vulnerabilities before they could be exploited by attackers.<\/p>\n
According to Bloomberg, which first reported the probe, a small group of users in a private, online forum gained access to the model via the computer system reserved for Anthropic’s external vendors.<\/p>\n
“We’re investigating a report claiming unauthorized access to Claude Mythos Preview through one of our third-party vendor environments,” an Anthropic spokesperson told AFP.<\/p>\n
The users got hold of Mythos by various means, including using access one of them had as a worker at a contractor for Anthropic, Bloomberg reported.<\/p>\n
Anthropic works with a small number of third-party vendors who help with model development.<\/p>\n
The firm has delayed a general release of\u00a0Mythos, which it says can spot undiscovered security holes that have existed for decades, in systems tested by both human experts and automated tools.<\/p>\n
It shared Mythos first with a few dozen key US tech and financial services players — such as Nvidia,\u00a0Amazon and\u00a0JP Morgan Chase — to allow them to improve their security infrastructure.<\/p>\n
But the company has also been accused of overhyping the powers of a technology which is its stock in trade, and the subject of fierce competition with rival OpenAI.<\/p>\n
