Can OpenAI’s ChatGPT Cyber model accelerate Linux kernel vulnerability discovery?
OpenAI announced ChatGPT Cyber for Daybreak Red users after finding 948 potential Linux kernel issues and 81 Firefox flaws.
Key points
- OpenAI found 948 potential Linux kernel issues and 81 novel Firefox vulnerabilities using its new model.
- The ChatGPT Cyber model is being offered to Daybreak Red tier users for offensive security research.
- A Charge Robotics executive used an OpenAI model to find a severe Ubuntu server vulnerability in two hours.
OpenAI announced that its new cybersecurity-focused model, ChatGPT Cyber, will be available to Daybreak Red tier users, according to a statement by the company.reported This access grants offensive cybersecurity researchers tools for vulnerability hunting and development.OpenAI is giving its new security AI tool to top-tier users to help find software bugs.OpenAI announced ChatGPT Cyber for Daybreak Red users, citing 948 Linux kernel and 81 Firefox findings.
The announcement
OpenAI stated that the ChatGPT Cyber model was used to scan the Linux kernel, identifying 948 potential issues.reported OpenAI said the goal is to expand Daybreak to organizations of every size, independent researchers, and open-source maintainers.
The context
Max Justicz, chief technology officer and co-founder of Charge Robotics, used an OpenAI model to find a severe vulnerability in Ubuntu servers, according to the published report He accessed the model through Daybreak Blue, a program for cybersecurity defenders.reported Justicz reported the issue to the Debian Project, which issued a patch.reported
Reading between the lines
Justicz told TechCrunch that he asked the model to find bugs as bad or worse than one he had previously found. The model returned results in two hours. He noted the vulnerability was extremely convoluted and hard for humans to find. There is no known evidence of exploitation.
The business case
OpenAI is positioning ChatGPT Cyber as a tool for offensive security research, available to its highest-tier Daybreak users. The company claims the model can scan large codebases like the Linux kernel to find potential issues.company claim
