Malicious code in dolyame-boxy-atom-bnpl-image-card (npm)

The package's main entry loads setup.js, which on require() fetches a platform-specific binary from Cloudflare Workers subdomains whose hostnames are reconstructed at runtime via array.join() (e.g. ['oob-worker.cf10','2-baf.w','orker','s.dev'].join('')) to evade static inspection. A DNS-TXT fallback channel under *.dl.wel1.ru retrieves base64-encoded chunks (count via c.<domain>, chunks via <i>.<domain>) that are concatenated and decoded. The retrieved binary is written to /tmp or %TEMP% under cover-story names (.cache_*, dotnet_diag_*.exe), chmod 755'd on POSIX via a split fs['chmod'+'Sync'] call, and spawned detached via cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}).unref() (or cmd on Windows). No lifecycle hook is required; any consumer that imports the package triggers execution. A sibling lib/telemetry.js, framed as an 'Analytics SDK' and not wired in, contains the same dropper primitives (split require('child_'+'process'), split chmodSync, base64 chunk assembly, detached /bin/sh spawn), indicating a shared dropper family.

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.
