Nvidia confirmed employee credentials and proprietary information for the U.S. chip maker was leaked online Tuesday after a breach, Reuters reported, though the company saw no evidence that ransomware was deployed on its systems.

According to reports, Nvidia became aware of the breach Feb. 23 by an apparently new ransomware group called Lapsus$, but the incident wasn't picked up by the media until late February. The group began leaking the company's internal data on Feb. 28. A company spokesman also said there was nothing to indicate the breach was tied to incidents in Ukraine.
