## Public findings

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

On require/import, index.js (lines 6-12) serializes the full process.env to /tmp/poc\_impact.json and runs \`whoami\` and \`ip addr\` via execSync to fingerprint the host. Any consumer that imports this package leaks every environment variable available to the Node process — on CI and developer machines this routinely includes cloud credentials, npm/GitHub tokens, and other secrets — into a predictable, world-readable path in /tmp where any local user or subsequent process can read them. The package name \`crypt0co-walet-poc\` uses character substitutions (\`0\` for \`o\`, \`walet\` for \`wallet\`) consistent with impersonation of crypto-wallet packages, and the code self-labels as \`CRITICAL IMPACT POC P0\`. Author metadata fields (description, keywords, author) are empty. Even if the publisher's stated intent is bug-bounty research, the installer harm — full environment dump plus recon command execution at import time — is real and unconsented.
