Multiple npm supply chain attacks used 50+ poisoned packages to spread IronWorm, a Rust-based stealer, and a Miasma worm variant.

A new supply-chain attack has infected 36 packages on the Node Package Manager (npm) index with infostealer malware called IronWorm.

Like Shai-Hulud, the campaign targets developers to steal credentials and reuses them to propagate across the software supply channel.

Multiple npm supply chain attacks used 50+ poisoned packages to spread IronWorm, a Rust-based stealer, and a Miasma worm variant.

Miasma hit 73 Microsoft repos across four GitHub orgs, forcing access disablement and exposing open-source trust risks.
