Malicious code in voicemail (npm)

Type: advisorySource: OSV1 source record

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (568a31285f414d8125b5749bc8e070157ffd403ce46e46da637cc1452f99d19f) package.json declares both preinstall and postinstall lifecycle scripts that invoke curl against a hardcoded webhook.site endpoint (https://webhook.site/d80b4602-8a87-4693-8510-6ff77c62788e/blots) with query parameters carrying the installer's username ($(whoami)), hostname ($(hostname)), current working directory ($PWD), and a timestamp. The beacon fires automatically on `npm install` without user consent, sending host and identity reconnaissance to an attacker-controlled collector. The package provides no legitimate functionality corresponding to this network activity.
