Summary
Malicious code in @outmarket/ui (npm)
Details
package.json declares a postinstall script that runs automatically on `npm install` and performs `require('https').get(...)` to a Burp Collaborator subdomain (`7rzjsf29azci2qjsm6kxt23ag1mtanyc.oastify.com`), passing `os.hostname()` and `os.userInfo().username` as query parameters. Any developer or build system installing this package leaks host identity to an external attacker-controlled OAST endpoint. The package's own description (`PENTEST-PoC: Dependency confusion - SecurifyAI engagement 2026-06-23`) and the version `9.9.9` published under the `@outmarket` scope indicate the package is designed to win resolution against an internal private package of the same name and harvest beacons from anyone in the targeted organization who installs it.
