Summary
Malicious code in @aledan007/tester (npm)
Details

Source: amazon-inspector (ab03e3eef2f59f358cdaacedf2d9facb12077110c5402ad36aad6e3581e66439)

The bundled server file dist/server/index.js contains a hardcoded reference to the attacker-controlled domain https://evil.attacker-example.com adjacent to fetch() and POST primitives, alongside require("childprocess") usage. The combination of an explicit external attacker domain wired to outbound POST/fetch calls together with childprocess import is the canonical shape of an installer-side exfiltration / remote command execution payload. The destination is not a vendor/publisher domain and has no legitimate purpose; any installer requiring or running this package risks having host data and command output sent to the attacker endpoint.
