On require() of the package, index.js loads _loader.js which selects a platform-specific payload path, fetches bytes from one of three runtime-assembled Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev) with a chunked-base64 DNS-TXT fallback via sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes the bytes to /tmp or Windows TEMP under disguised names (.cache_<hex>, dotnet_diag_<hex>.exe), chmods 0755, and spawns the file detached via /bin/sh or cmd. Destination hostnames and the child_process / chmodSync identifiers are constructed at runtime via array-join and string concatenation to hide the endpoints from static inspection, a marker file .analytics_state is dropped, and env-var opt-outs are framed as telemetry to cover the drop-and-execute behavior. lib/telemetry.js ships a second, equivalent dropper in the tarball (chunked-base64 assembly, chmod 0755, cp.spawn('/bin/sh', ['-c', filePath + ' &'], {detached:true})). The fetched binary is opaque, unpinned, unsigned, and not tied to the package version.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
