Nvidia retaliated against the hacker group that stole over 1TB of the company's data by sneaking back into the hacker's system and encrypting the stolen data.
According to Tom's Hardware, LAPSU$ is a South American extortion group in South America, hacked Nvidia's mail server and installed malware on the software distribution server.
The hacker group extracted over 1TB of Nvidia's data. However, it seems that Nvidia has identified the attackers and counter attacked. It infected the perpetrators' system with ransomware and encrypted the stolen data.
The group insisted that it had a backup of the data, though so it was not a total victory to Nvidia. However, it is not clear what else Nvidia obtained which might cause the hackers to receive a visit from the local plod.
