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.\n\n## Source: ghsa-malware (c25086e2f848341d091e22c0b53ca92f47f2bc94707307b739ed6dfc24be246f)\nAny computer that has this package installed or running should be considered fully compromised.
