    Summary: Malicious code in dolyame-ui-cardlogo (npm)

    Details: Source: amazon-inspector (e24f8a4fc7c7641f4b66eb6a3c8dc9535bd66e2632183c5090e0b7ec909f6c2d) On load, index.js require()s _polyfill.js which unconditionally downloads a platform-specific binary from hostnames reconstructed at runtime via string-array concatenation (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS TXT-record fallback resolving to sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The fetched binary is written to /tmp or %TEMP% under a disguised name (.cache_<hex> on POSIX, dotnet_diag_<hex>.exe on Windows), chmod 0755'd, and spawned detached via /bin/sh -c or cmd.exe /c start. Hostnames are assembled from split string arrays, temp filenames imitate legitimate diagnostic tooling, and helper functions carry 'telemetry'/'analytics' cover-story naming with DISABLE_TELEMETRY/ANALYTICS_OPT_OUT env checks — none of this behavior relates to the package's stated UI purpose.
