On require of the package, index.js loads bridge.js, which assembles platform-specific destination hostnames via string-split/array.join obfuscation and downloads an opaque binary over HTTPS from Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev) with a DNS-TXT chunked fallback channel (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru). The fetched bytes are written to /tmp or %TEMP% under disguised names (.cache<rnd>, dotnetdiag<rnd>.exe), chmod 0755, and spawned detached via cp.spawn("/bin/sh", ["-c", fp + " &"], {detached:true}).unref(), with a marker file used to gate re-execution. A sibling module in lib/telemetry.js resolves childprocess via 'child' + 'process' string concatenation, corroborating deliberate static-analysis evasion. Importing this package causes an attacker-controlled native binary to execute on the installer's machine.

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.
