A group of unauthorized users has reportedly gained access to Mythos<\/a>, the cybersecurity tool recently announced by Anthropic. <\/p>\n Much has been made of Mythos and its purported power \u2014 an AI product designed for enterprise security that, in the wrong hands, could become a potent hacking tool, according to the company. Now, Bloomberg has reported<\/a> that a \u201cprivate online forum,\u201d the members of which have not been publicly identified, has managed to gain access to the tool through a third-party vendor.<\/p>\n \u201cWe\u2019re investigating a report claiming unauthorized access to Claude Mythos Preview through one of our third-party vendor environments,\u201d an Anthropic spokesperson told TechCrunch. The company said that, so far, it has found no evidence that the supposedly unauthorized activity has impacted Anthropic\u2019s systems in any way.<\/p>\n The unauthorized group tried a number of different strategies to gain access to the model, including using \u201caccess\u201d enjoyed by the person who was interviewed by Bloomberg. That person is currently employed at a third-party contractor that works for Anthropic, the outlet reported.<\/p>\n Members of the group are part of a Discord channel that seeks out information about unreleased AI models, the outlet reported. The group has been using Mythos regularly since gaining access to it, and provided evidence to Bloomberg in the form of screenshots and a live demonstration of the software.<\/p>\n Bloomberg reports that the group, which supposedly gained access to the tool on the very same day it was publicly announced, \u201cmade an educated guess about the model\u2019s online location based on knowledge about the format Anthropic has used for other models.\u201d The group in question is \u201cinterested in playing around with new models, not wreaking havoc with them,\u201d the source told the outlet. <\/p>\n Mythos was released to a select number of vendors, including big names like Apple, as part of an initiative called Project Glasswing. The limited release of the model was designed to prevent its use by bad actors. The tool could be weaponized against corporate security instead of bolstering it, Anthropic said.<\/p>\n Techcrunch event<\/p>\n \n\t\t\t\t\t\t\t\t\tSan Francisco, CA<\/span> If true, unauthorized use of Mythos could spell trouble for Anthropic, which provided the exclusive release to allay the company\u2019s concern for enterprise security.<\/p>\n<\/div>\n When you purchase through links in our articles, we may earn a small commission<\/a>.
