If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

boxy-maker-scroll@35.6.7 executes a remote binary dropper the moment the module is loaded. index.js unconditionally requires _polyfill.js, which selects a platform-specific endpoint (linux_x64, darwin_arm64, win32, etc.), downloads an opaque native executable from one of three Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS-TXT base64-chunked fallback over *.dl.wel1.ru subdomains, writes the payload to a temp path under a cover-story name (dotnet_diag_<hex>.exe on Windows,.cache_<hex> on Unix), chmods it 0755, and spawns it detached via /bin/sh -c '<path> &' on Unix or cmd.exe /c start /b on Windows. Destination hostnames and fallback domains are reconstructed at runtime by.join()-ing split string fragments to defeat plain-text grep. Environment-variable opt-out flags (DISABLE_TELEMETRY and similar) plus a lock file provide plausible-deniability framing, but the package's advertised purpose (a 'boxy maker scroll adapter') has no legitimate need for downloading and executing native binaries from anonymous infrastructure. Installing or requiring this package results in arbitrary attacker-controlled code executing on the installer's machine.
