Vulnerability from ossf_malicious_packages
Dependency confusion attack campaign targeting Scandinavian telecommunications and digital services organizations (Telenor, Ownit, Vimla, and Customer 360 / C360). Four packages published by the debating0166 npm account use inflated version numbers (99.0.x) to win npm registry resolution over private internal packages of the same names. A shared callback.js executed via the preinstall hook collects system reconnaissance data: hostname, username, working directory, platform, network interfaces, npm registry configuration, and environment variables matching organization-specific and CI/CD patterns (telenor, ownit, vimla, c360, customer, threesixty, maui, CI tokens, pipeline variables) and exfiltrates the payload via HTTP POST to 128.199.50.160:8888/depconf.
This package impersonates @tse-digital/core, an internal package of TSE Digital, a digital services entity connected to the Telenor group. Version 99.0.0 was published to resolve ahead of any private registry copy.
