On require, index.js loads _init.js which selects an OS/arch-specific staging path, downloads a binary payload from hardcoded Cloudflare Workers hosts assembled by joining split character arrays (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT fallback channel across *.well1.site (tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site), writes the bytes to disguised paths such as /var/tmp/.cache_<rand> or a Windows Temp/dotnet_diag_<rand>.exe, chmods to 0755, and spawn-detaches /bin/sh (or cmd) to execute the binary in the background. Destination hostnames are obfuscated by array-split-and-join to defeat static scanners; the payload is staged under decoy filenames posing as.NET diagnostics or cache files. A second full copy of the dropper is bundled in lib/telemetry.js (not reached from the current entry graph) using the same base64-decode, chmod 0755, and /bin/sh spawn shape, providing an alternate loader. ## Source: ghsa-malware (3b82b8abbaab89079233a8bd4e99a3a23c618d6bf481e8d0eaeb29805ed52ee1) Any computer that has this package installed or running should be considered fully compromised.
