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(), index.js loads _loader.js which selects a platform-specific payload path, fetches bytes over HTTPS from obfuscated hosts assembled via string-split concatenation (oob-worker.cf1-02-baf.workers.dev and siblings) with a DNS-TXT fallback that reassembles a base64 payload from numbered TXT records under sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes the payload to /tmp/.cache_<rand> or %TEMP%/dotnet_diag_<rand>.exe, chmods 0755, and detached-spawns it via spawn('/bin/sh',['-c', fp+' &']) or spawn('cmd',...). No signature or hash verification is performed, hosts are obfuscated to evade static analysis, staging paths and filenames mimic telemetry/diagnostic naming, and the package name misappropriates a payments-BNPL brand context that has no legitimate reason to fetch and execute arbitrary binaries at import time.
