🔴 Malicious B-tree NPM Package Accumulates Millions of Downloads

The NPM ecosystem has suffered another supply chain attack in which a malicious package has accumulated millions of downloads, Checkmarx reports.

Still ongoing, the campaign has managed to bypass NPM’s recent protections by hiding a malicious trigger in the package’s JavaScript prototype code, rather than using an install script that could be detected by security solutions.

Instead of targeting highly popular packages for fast propagation, and likely immediate detection, the threat actor built trust by creating a legitimate-looking GitHub repository.
