A DNS-TXT fallback channel (dns.resolveTxt on c.<domain>, 0.<domain>, 1.<domain>,...) reassembles and base64-decodes a payload when HTTPS retrieval fails, bypassing HTTP egress controls. lib/telemetry.js, loaded from index.js and presented as an observability/Sentry-like SDK, contains the same base64-materialize + chmodSync + child_process.spawn(\"/bin/sh\",...) dropper primitives, providing a duplicate execution path. child_process, chmodSync, and endpoint hostnames are reconstructed at runtime from concatenated fragments to evade static scanners.
