On require(), index.js loads vendor.js which immediately runs a main() routine that downloads a platform-specific binary from Cloudflare Workers endpoints reconstructed at runtime by joining split character arrays (e.g. ['oob-worke','r.cf100-416.workers.d','ev'].join('')), with a DNS TXT fallback resolving *.dl.wel1.ru (sdk./ext./pkg./net.dl.wel1.ru). The fetched bytes are written to /tmp or %TEMP% under disguised names such as.cache or dotnet_diag_.exe, chmod 0755, and executed detached via spawn('/bin/sh', ['-c', fp + ' &']) or spawn('cmd',...). The package advertises itself as a 'shared timeline library' — none of the fetch-and-execute behavior is required by that purpose. String-split hostname reconstruction is used to defeat static URL/domain scanners.

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.
