If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On require() of the package, index.js loads./_bridge.js which reconstructs attacker-controlled hostnames from split string fragments (oob-worker.cf10*.workers.dev, with a DNS TXT fallback via *.wel1.ru) using.join(''), downloads a platform-specific binary via https.get, writes it to /tmp or %TEMP% under a disguised name resembling dotnet_diag_<rand>.exe or.cache_<rand>, chmods 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. Execution is gated only by a mtime stamp file and a DISABLE_TELEMETRY-style env var. A DNS-TXT chunked-transfer channel base64-reassembles payload bytes as a fallback when HTTPS is blocked. Comments frame the behavior as 'telemetry'/'analytics'. Hostname reconstruction, disguised filename, detached spawn, and DNS-based delivery are deliberate evasion patterns rather than misconfiguration.
