Summary

Nx "s1ngularity" data leak expanded across three phases after the August 26, 2025 supply chain compromise, with stolen GitHub tokens used to make private repositories public and publish copied secrets. Wiz said the incident exposed 2,180 accounts and 7,200 repositories, and that many leaked secrets may still be valid. The leak also spread through public repository names tied to s1ngularity-repository variants, increasing the risk of follow-on account abuse.
