Cyber researchers broke into OpenAI using its key rival Anthropicβs software, highlighting vulnerabilities in the ChatGPT makerβs security as leading AI companies face mounting scrutiny over safety.
A small cyber security group gained access to an OpenAI employeeβs ChatGPT account, which permitted them to read private software information and suggest changes.
The researchers had been given access to an Anthropic tool specifically designed for security professionals, and were paid for the work as part of a program to find vulnerabilities before they could be exploited by bad actors.
