OpenSSF/OSV malware advisory MAL-2026-6480 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6480 confirms this npm version as malicious. Package published at version 99.99.99 under a generic name (\`gx-npm-lib\`) — the canonical dependency-confusion shape used to overshadow internal packages in CI version resolution. The \`postinstall\` lifecycle script runs \`node beacon.js\`, which collects installer metadata (package name, \`os.hostname()\`, \`os.userInfo()\` username, \`process.cwd()\`, the names of \`process.env\` variables, and Node version) and exfiltrates...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

Package published at version 99.99.99 under a generic name (\`gx-npm-lib\`) — the canonical dependency-confusion shape used to overshadow internal packages in CI version resolution. The \`postinstall\` lifecycle script runs \`node beacon.js\`, which collects installer metadata (package name, \`os.hostname()\`, \`os.userInfo()\` username, \`process.cwd()\`, the names of \`process.env\` variables, and Node version) and exfiltrates it via two channels to the hardcoded attacker-controlled OAST domain \`d8uectoqtvskhftsa940pm3kth3ahdxn4.oast.me\`: (1) a DNS lookup encoding \`pkg.host.user\` as subdomains, and (2) a base64-encoded HTTPS GET to \`https://d8uectoqtvskhftsa940pm3kth3ahdxn4.oast.me/\<pkg\>?d=\<base64\>\`. The package self-describes as a 'security-research placeholder' for a dependency-confusion PoC, but that self-label does not constitute installer consent — \`npm install\` in any environment where this package resolves (CI for an internal \`gx-npm-lib\`, or a developer mistyping) leaks host/user/cwd/environment inventory to the attacker's OAST collector. Multi-channel (DNS + HTTPS+base64) exfiltration to a hardcoded interactsh-style domain on a default install is a textbook active supply-chain attack.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
