Details

**Severity:** Critical

**Affected versions:** `= 1.1.11`

This package is part of a malicious npm campaign published by the `biz44` account.

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.
