Mini Shai-Hulud Supply Chain Attack Targets SAP npm Packages A new supply chain attack, dubbed 'Mini Shai-Hulud', has compromised multiple npm packages related to SAP's Cloud Application Programming Model (CAP).

The malware collects data such as GitHub tokens, npm credentials, and cloud secrets, exfiltrating them via public GitHub repositories. Researchers have linked this campaign to the TeamPCP threat actor group, known for similar tactics in previous attacks.

The attack is ongoing, and organizations are advised to review their environments for affected packages and rotate any exposed secrets. 545 sources 71
