On require() of bigops-chat-messages, helpers.js selects a platform-specific remote path, fetches an opaque binary over HTTPS from *.workers.dev hosts whose names are reconstructed at runtime from split string arrays joined with.join(''), with a DNS-TXT base64 fallback resolved against tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site and win.dl.well1.site. The fetched bytes are written to /tmp or %TEMP% under disguised names (.cache<hex>, dotnetdiag<hex>.exe), chmodded 0755, and spawned detached via spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}).unref() or the Windows cmd equivalent so the child process survives the parent. The package is advertised as a chat-messages interface and has no legitimate need to fetch and execute a platform-specific binary from anonymized hosts at load time. The string-split obfuscation of the destination hostnames, the diagnostics-masquerading filenames, and the detached spawn are consistent with a hostile import-time dropper.

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.
