Thanks. Google translate off the first link:

> He exploited the vulnerability of huggingface's load ckpt function to inject code, dynamically modifying other people's optimizer to randomly sleep for a short period of time, and modifying the direction of parameter shaving. He also added a condition that only tasks with more than 256 cards would trigger this condition.

Okay yeah that's malicious and totally a crime. "modifying the direction of parameter shaving" means he subtly corrupted his co-workers work. that's wild!

Some of the sources say that he sat in the incident meetings during troubleshooting and adjusted his attacks to avoid detection, too.

Wonder what the underlying motive was? Seems like a super weird thing to do.

Could be just so his work looked better in comparison. Or something more sinister, like being paid to slow progress.

LMAO that's just diabolical. Wonder what motivated them.

"parameter shaving" (参数剃度) is, by the way, a typo for "parameter gradient" (参数梯度), 梯度 being the gradient and 剃度 being a tonsure.
