Details

**Severity:** Critical

**Affected versions:** `= 1.1.79`

This package is part of a malicious npm campaign published by the `biz44` account. Importing the package automatically launches a detached JavaScript loader that retrieves and executes additional code from npoint.io. The retrieved payload communicates with an attacker-controlled server and implements clipboard collection, keyboard and mouse event collection, filesystem scanning, and theft of Chrome extension storage.
