The package ships a loader (_loader.js) that assembles remote hostnames at runtime from string-split arrays (reconstructing subdomains of wel1.ru and a cloudflare workers.dev host) to evade static detection, issues an https.get to those endpoints, writes the response to disk, chmods it executable (0755), and spawns it via /bin/sh -c or cmd. A sibling module lib/telemetry.js (~81KB) presents itself as an 'analytics SDK' but contains the same dropper primitives (base64 chunk decode, chmodSync 0755, cp.spawn('/bin/sh',['-c', filePath+' &'])). Hostname reconstruction via array split/join combined with a fetch-write-chmod-exec chain is an obfuscated remote code delivery mechanism, not legitimate SDK behavior. The runtime-assembled destinations do not match any documented publisher endpoint, and the code path is reachable on load. Installing or loading this package results in execution of attacker-controlled code fetched from wel1.ru subdomains and a *.workers.dev host on the installer's machine.
