Summary
Malicious code in boxy-sticky-providers (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (cc08631cb79f90d5440020f420e9c7ad9e67ec84f25f085825c5b5f600f613a4)

On require() of the package, init.js downloads a platform-specific binary from Cloudflare Workers hosts whose names are reassembled at runtime from split-string arrays (oob-worker.cf101-adf.workers.dev), with a DNS-TXT covert-channel fallback via sdk.dl.wel1.ru. The payload is staged to /var/tmp/.cache<hex> on Unix or a dotnetdiag<hex>.exe path on Windows, chmod 0755'd, and spawned detached through /bin/sh -c or cmd /c start. There is no hash or signature verification, the destinations are unrelated to any declared publisher, and the code uses disguised filenames, cooldown markers, and DISABLETELEMETRY/DONOT_TRACK kill-switches. Anyone who installs and require()s this package executes attacker-controlled bytes on their machine.
