--- _-= Per source details.

Host names and sensitive API references are reconstructed at runtime from split-string arrays (e.g. host strings assembled via.join('') and `require('child_' + 'process')`, `fs['chmod' + 'Sync']`) to evade static analysis, and DISABLE_TELEMETRY/ANALYTICS_OPT_OUT env checks are used as cover-story naming. lib/telemetry.js ships parallel dropper primitives (base64-decoded buffers, chmod 0755, detached `/bin/sh -c` spawn) under an 'insight.node' analytics SDK disguise. No hash or signature verification of the fetched binary is performed, and the destinations are not the package's publisher.
