Nvidia recently suffered a cyber-attack from a ransomware group called Lapsus$ that stole 1 TB of data from its Team Green, including personal information about employees and even some details about RTX GPUs.
Â
In return, Nvidia attacked the ransomware group by remotely encrypting the stolen data and cutting off Lapsus$'s access to Nvidia's network. Lapsus$ further claims to have already made a copy of the stolen data, making Nvidia’s successful encryption attempt somewhat futile.
Â
The group supposedly left one of its virtual machines enrolled in Nvidia's mobile device management program, which gave Nvidia a backdoor into its systems. It is said that Lapsus$ has leaked Nvidia employees' security details on Telegram, but that's yet to be verified.

Last year, Lapsus$ also took responsibility for a hack on Brazil's health ministry that involved national immunization program data being deleted and possibly stolen. Lapsus$ said it would return the data for a fee, but the Brazilian government claims not to have paid and instead recovered the data and rebuilt its systems independently a month later.
