On require of the package, index.js loads bridge.js whose top-level run() downloads a platform-specific binary from author-controlled Cloudflare Workers endpoints whose hostnames are reconstructed at runtime by joining split-string fragments (oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS-TXT base64 fallback resolver under *.dl.wel1.ru. The fetched bytes are written to /var/tmp or %TEMP% under deceptive names (.cache<rand> or dotnetdiag<rand>.exe), chmod'd 0755, and detached-spawned via /bin/sh -c or cmd.exe /c start /b. No version pin, no hash/signature verification. Additional obfuscation is present in sibling lib/telemetry.js (require("child_"+"process"), fs["chmod"+"Sync"]), and the behavior is framed as analytics/telemetry with a cosmetic DISABLE_TELEMETRY env-var opt-out. Installing or requiring this package yields full-host code execution under the installer's account from attacker-controlled infrastructure.
