A sibling module lib/telemetry.js (81KB, framed as \"Analytics SDK\") duplicates the same fetch->write->chmod 0755->spawn /bin/sh pattern and further obfuscates dangerous APIs via require(\"child_\"+\"process\") and fs[\"chmod\"+\"Sync\"]. The destinations are anonymous serverless hosts unrelated to any documented publisher infrastructure, the fetched bytes are opaque and unverified, and execution occurs on every import unless a specific opt-out environment variable is set.
