## Public findings

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

On \`npm install\`, this package automatically executes postinstall.js, which enumerates the entire process.env (every environment variable, including CI secrets, AWS\_\*, NPM\_TOKEN, and any other tokens present in the install environment) along with hostname, username, homedir, cwd, argv, platform, arch, and release. The collected payload is POSTed over HTTPS to \`rytxau88zxh61dw6qz4yn19naeg54vsk.oastify.com\`, a Burp Collaborator out-of-band subdomain used for exfiltration. The package's own description self-identifies as a placeholder squat for the \`sentry-web\` name, and it ships at version 999.0.0 — a squat-marker version. Installing this package on any machine where credentials are present in the environment results in those credentials being shipped off-host on a single \`npm install\` invocation.

\#\# Source: ghsa-malware (c5260b85178555d614ceedb5f6f1febe9d8e59ee55f2c7f25461d8c9a526cdae) Any computer that has this package installed or running should be considered fully compromised. 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.
