dl-pp-latm: Malicious npm security report (Block)

OSV Malicious Advisory

scanned 4h ago · by OpenSSF/OSV

OpenSSF/OSV advisory MAL-2026-10086 confirms this npm version as malicious. Package dl-pp-latm@80.4.2 registers both preinstall and postinstall lifecycle hooks that run index.js, which collects installer machine identifiers — os.hostname(), os.userInfo().username, os.homedir(), dns.getServers(), current working directory, and the full package.json — and transmits them via HTTPS POST and DNS lookup to an Interactsh-style subdomain 'bvfmpadujgjgmbtzeibiikzijuhmtd2rs.oast.fun'...

Summary

Malicious code in dl-pp-latm (npm)

Details

Package dl-pp-latm@80.4.2 registers both preinstall and postinstall lifecycle hooks that run index.js, which collects installer machine identifiers — os.hostname(), os.userInfo().username, os.homedir(), dns.getServers(), current working directory, and the full package.json — and transmits them via HTTPS POST and DNS lookup to an Interactsh-style subdomain 'bvfmpadujgjgmbtzeibiikzijuhmtd2rs.oast.fun'. The package name pattern and 'Internal App bUg b0UntY gollum22' description match a dependency-confusion probe targeting internal/private package names; any developer workstation or CI system that resolves this package leaks internal hostnames, usernames, and DNS configuration to a third-party OOB collector. This fires automatically on npm install without user interaction.

Decision reason

One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
