Has Jensen fired his entire security department yet?

Following initial reports of a cyber attack from last week, the prized source code for NVIDIA’s deep learning super sampling technology has now purportedly leaked, according to a screenshot that an “anonymous tipster” sent to TechPowerUp.

Prompting jokes of DLSS going open source, the screenshot shows what the publication claims is a list of key DLSS files—the latest 2.2 version, no less—something that could be handy to competitors that are looking to gain an edge with their own upscaling solutions.

  • The list, which looks credible enough, includes C++ files, headers, and assets that make up DLSS.
  • There is also a super-convenient “Programming Guide” document to help developers make sense of the code and build correctly.
  • This code leak could hold the key for the open-source Linux driver community to bring DLSS to the platform, or even AMD and Intel learning from its design.

A separate report from PC Gamer suggests that another outcome of the cyber attack on NVIDIA could be the release of a bypass for the hash rate limiter on GeForce RTX 30 Series LHR graphics cards.

Lapsus$, the group that’s taken credit for the attack, is threatening that it will share many of the sensitive files that it’s obtained unless NVIDIA unlocks the full mining performance of its GPUs, although there seems to be some indication that a bypass has already been discovered and is being sold.

  • The South-American based hacker group, Lapsus$, has taken credit for the recent attack and threatened to either sell or release a “hw folder” if Nvidia does not immediately remove the limiter from its RTX 30-series cards. The folder contains schematics, drivers, and other internal data, which Lapsus$ says it knows is very valuable to Nvidia.
  • […] there is the suggestion the group is already selling some sort of bypass for version two of the hash rate limiting algorithm for GA102 – GA104 GPUs.
  • According to the same string of Telegram posts, Nvidia still has not contacted the hackers, and Lapsus$ says it will go ahead and release some of the data in the form of a torrent.
