May 14 (Reuters) - ‌OpenAI said ​on ​Wednesday it found no evidence that its user data was ‌accessed after a security issue involving ⁠a supply-chain attack on TanStack npm, an ‌open-source library.

Here are some ‌details:

• The ChatGPT-maker said it found no evidence that its production systems ​or intellectual property were compromised, or that their software was ⁠altered

• OpenAI said two employee devices in its corporate ​environment were impacted after TanStack, a widely used open-source library, got ​compromised earlier this week

• ‌Limited credential material was exfiltrated from these code repositories and ⁠no other information or code was impacted, OpenAI said

• The AI firm said ⁠that it isolated the impacted systems immediately after ​the attack and temporarily restricted code-deployment workflows, to contain impact

• OpenAI said it is rotating ‌code-signing certificates, which would require macOS users to update their ‌applications

• OpenAI did not immediately ⁠respond to a ‌Reuters request for ​further details
