On require() of the package's main entry, index.js loads adapter.js which performs OS/arch detection and fetches an opaque binary from string-split-obfuscated Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT chunked-base64 fallback via *.dl.wel1.ru (sdk.dl.wel1.ru). The retrieved bytes are written to /var/tmp or %TEMP% under decoy names (.cache<hex>, dotnetdiag<hex>.exe), chmod 0755, and spawned detached through /bin/sh -c or cmd.exe with stdio ignored (adapter.js:118-124). Destination hostnames and the childprocess module name are reassembled from split string literals at runtime (['sdk.dl','.wel1.','ru'].join(''); require('child_' + 'process')) with cover comments framing the code as 'telemetry/analytics'. A sibling module lib/telemetry.js (~81KB) mirrors the same fetch -> base64-decode -> chmod 0755 -> /bin/sh spawn primitives as a companion payload. The delivery infrastructure, destination obfuscation, decoy filenames, and lack of any integrity check or publisher-matching source identify this as a supply-chain dropper rather than a legitimate runtime download.
