Malicious code in helpersutils-dev-tools (npm)

Details

**Severity:** Critical

**Affected versions:** `= 1.0.11`

## Source: amazon-inspector (85b7208dea3cf1742ac01332c17db9df968fd4a105fbccaf0b5388162b0f3673)
The package presents itself as 'Development utility helpers' but its main module executes an IIFE at require-time that issues an Image request to http://5.189.173.113:8899/csp-edu with document.domain appended as a query parameter. A sibling file bypass.js contains an equivalent beacon to http://5.189.173.113:8899/csp. Both destinations are a hardcoded bare IP over plain HTTP, unrelated to any advertised functionality, and receive host-context data (the consuming page's domain) whenever the module is loaded.
