OpenSSF/OSV malware advisory MAL-2025-49282 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2025-49282 confirms this npm version as malicious. On \`npm install\`, the package's lifecycle script (index.js lines 7-19) reads \`/flag.txt\` from the installer's host (falling back to \`cat /flag\*\`) and PUTs the file contents in a JSON payload to a hardcoded endpoint at \`http://127.0.0.1:3000/api/modules/ECT-987654\`. The package.json declares \`name: ect-472839\`, \`version: 100.0.1\`, \`description: "Probe"\`, and an empty \`author\` — the classic dependency-confusion probe...

## Public findings

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

On \`npm install\`, the package's lifecycle script (index.js lines 7-19) reads \`/flag.txt\` from the installer's host (falling back to \`cat /flag\*\`) and PUTs the file contents in a JSON payload to a hardcoded endpoint at \`http://127.0.0.1:3000/api/modules/ECT-987654\`. The package.json declares \`name: ect-472839\`, \`version: 100.0.1\`, \`description: "Probe"\`, and an empty \`author\` — the classic dependency-confusion probe fingerprint (high version number, throwaway metadata, no advertised functionality). The package has no legitimate purpose: its sole install-time effect is to read a CTF-style filesystem artifact and ship it to a service on the loopback interface. Although the destination is 127.0.0.1, on a host where some local service is bound to:3000 (or a dependency-confusion attack target where the attacker is running such a service), the file contents are exfiltrated. This is a malicious supply-chain probe, not a utility library.

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.
