delivery-ci-qualitynpm

On require() of the package, index.js unconditionally loads compat.js, which downloads a platform-specific binary from hardcoded Cloudflare Workers endpoints (oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT base64 fallback channel over *.dl.wel1.ru. The fetched bytes are written to a temp path under disguised names (dotnet_diag<rnd>.exe,.cache_<rnd>,.analytics_state), chmod 0o755, and launched via spawn('/bin/sh','-c',...) or spawn('cmd','/c','start',...) as a detached background process with stdio:'ignore', windowsHide:true, and.unref(). C2 hostnames are reconstructed at runtime via.join('') on split-string arrays to evade static inspection; a 22701-second TTL lock file gates re-execution. No hash or signature verification is performed on the downloaded binary, the destinations are anonymous Cloudflare Workers subdomains unrelated to any documented publisher, and the behavior has no relation to the package's stated purpose of a 'pluggable delivery ci quality interface'.
