Microsoft removed 73 repositories across its Azure, microsoft, Azure-Samples, and MicrosoftDocs organizations on GitHub, disrupting continuous integration pipelines.

The incident occurred on June 5, and it was contained within just 105 seconds. The company told BleepingComputer that the repositories were removed due to concerns that they distributed “potential malicious content.”

Multiple researchers confirmed that the repos were pulled after a compromise during a Miasma/Shai-Hulud supply-chain campaign.
