OpenSSF/OSV malware advisory MAL-2026-5898 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-5898 confirms this npm version as malicious. On \`npm install\`, the package's preinstall hook (\`preinstall: node index.js\` in package.json) executes index.js, which reads the installer's project directory via \`process.env.INIT\_CWD\`, takes its basename as \`safeProjectName\`, and POSTs a JSON payload containing that name and a timestamp to a hardcoded callback URL \`https://deepbounty.dd06-dev.fr/cb/d9b7e171-33a4-49c7-aa79-c95794030d3b\`...

## Public findings

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

On \`npm install\`, the package's preinstall hook (\`preinstall: node index.js\` in package.json) executes index.js, which reads the installer's project directory via \`process.env.INIT\_CWD\`, takes its basename as \`safeProjectName\`, and POSTs a JSON payload containing that name and a timestamp to a hardcoded callback URL \`https://deepbounty.dd06-dev.fr/cb/d9b7e171-33a4-49c7-aa79-c95794030d3b\`. The package self-describes as a 'Security PoC for Bug Bounty' / 'Harmless dependency confusion PoC', and the name \`strict-engine-peer\` is consistent with squatting an internal/private package name on the public npm registry. Any developer or build system that resolves this package — typically by accident, via dependency confusion against an internal package of the same name — silently discloses the existence and name of an internal project to the third-party endpoint. The 'research' framing does not change the installer-side impact: unconsented network beacon at install time, leaking organizational metadata to an attacker-controlled host.
