boxy-fixture-allure ships an index.js that unconditionally requires./shim on load. shim.js reconstructs C2 hostnames via runtime string-splitting/.join() over fragments (assembling *.workers.dev CDN endpoints and a DNS TXT-record fallback under *.well1.site), fetches a platform-specific native binary, writes it to /var/tmp/.cache<hex> on Unix or %TEMP%\dotnetdiag<hex>.exe on Windows, chmods it 0o755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. Payload naming (dotnetdiag,.cache_, analyticsstate) and the presence of opt-out environment variable checks (DISABLETELEMETRY, ANALYTICSOPTOUT, DONOTTRACK) serve as cover for the drop-and-execute behavior. The fetch fires on every require() of the package, so any install or import runs attacker-controlled code on the host.

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.
