OpenAI updated its security certificates and is requiring all macOS users to update to the latest versions after determining its products, along with many others, were impacted by a widespread supply-chain attack that briefly infected a popular open-source library in late March, the company said in a blog post Friday.
The artificial intelligence vendor said it “found no evidence that OpenAI user data was accessed, that our systems or intellectual property was compromised, or that our software was altered.”
Yet, because a GitHub workflow the company uses to sign certificates for macOS applications downloaded and executed a malicious version of Axios, the company is treating the soon-to-be defunct certificate as compromised.
A North Korean hacking group injected malware into two versions of Axios after it compromised the lead maintainer’s computer via social engineering and took over his npm and GitHub accounts. Jason Saayman, the lead maintainer for Axios, said the malicious versions of the software were live for about three hours before removal.
Google Threat Intelligence Group, which tracks the threat group as UNC1069, said the impact of the attack was broad with ripple effects potentially exposing other popular packages. The JavaScript libraries flow into dependent downstream software through more than 100 million and 83 million downloads weekly.
The attack was discovered just weeks after a series of other open-source tools, including Trivy, were compromised by UNC6780, also known as TeamPCP, resulting in aggressive extortion attempts.
OpenAI insists the malware that infected Axios did not directly impact its certificate, which is designed to help customers confirm they are downloading legitimate software.
“The signing certificate present in this workflow was likely not successfully exfiltrated by the malicious payload due to the timing of the payload execution, certificate injection into the job, sequencing of the job itself, and other mitigating factors,” the company said in the blog post. “Nevertheless, out of an abundance of caution we are treating the certificate as compromised, and are revoking and rotating it.”
Older versions of OpenAI’s macOS apps may lose functionality and will no longer be supported when the certificate is fully revoked May 8, the company said.
OpenAI, which hired a third-party digital forensics and incident response firm to aid its investigation and response, pinned the root cause of the security issue on a misconfiguration in its GitHub workflow. The company said it corrected that error and worked with Apple to ensure fraudulent apps posing as OpenAI cannot use the impacted certificate.
The 30-day window is designed to minimize disruption for users, but OpenAI said it will speed up the revocation deadline if it identifies any malicious activity. The company did not immediately respond to a request for comment.
