It looks like Microsoft's DevOps libraries for Azure Functions might have been compromised. No statement yet but Github is nuking Microsoft's own repos.

The Blight Reaches Microsoft: 73 Repos Disabled in 105 Seconds

GitHub disabled 73 Microsoft repositories across four of its GitHub organizations — the entire Azure Functions org, the whole Durable Task family, and a row of AI sample apps — in a 105-second sweep on June 5. The recompromised durabletask package sits at the center, and the fingerprints point at the open-sourced Miasma worm.

As far as I know there's no public statement from Microsoft yet, but yes, I've heard they've been compromised and have been serving compromised code.
@GossiTheDog when weren't they?
