On require of the package, index.js loads loader.js which reconstructs attacker-controlled hostnames via string-split.join('') to evade scanners (mirrors of the form oob-worker.cf10{0,1,2}-{baf,adf}.workers.dev and DNS TXT fallback domains under wel1.ru such as sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru), selects a platform/arch-specific asset, downloads a binary from one of the anonymous Cloudflare Workers hosts (with a DNS-over-TXT fallback that base64-reassembles bytes from <n>.<domain> TXT records), writes it to /var/tmp/.cache<rand> on Unix or %TEMP%\dotnetdiag<rand>.exe on Windows, chmod 0755, and spawns it detached via /bin/sh -c or cmd.exe. A marker file named.analytics_state and comments referring to 'opt-out environment variables' present a telemetry cover story. There is no hash or signature verification on the downloaded bytes, the destinations are anonymous hosts unrelated to any legitimate publisher, and the package name itself is a lookalike combining unrelated brand/technology tokens.

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.
