MAL-2026-13754

Summary: Malicious code in dependencyfsdsfdsfg (npm)

Details: Source: amazon-inspector (c53ad8755f0eb26cef8c05b49cdad8c69b93072e0d9ed176b071a7d367349cab) package.json declares `postinstall: node index.js`, causing index.js to run automatically on `npm install`. The script collects the installer's username (via `whoami`), `os.hostname()`, `process.cwd()`, and non-internal IPv4 addresses from `os.networkInterfaces()`, then sends them as query-string parameters via HTTPS GET to the hardcoded endpoint `https://xghhv5sajm33m7krgi4n8my0mrsig84x.oastify.com`. The `*.oastify.com` host is a Burp Collaborator out-of-band interaction domain. Package metadata is consistent with a dependency-confusion probe: gibberish name `dependencyfsdsfdsfg`, version `99.9.0`, empty author/description/keywords.

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.
