# MAL-2026-13555: Malicious code in dolyame-ui-cardlogo (npm) - **Type:** Malicious package - **Package:** `dolyame-ui-cardlogo` (npm) - **Published:** 7 Aug 2026 ## What is MAL-2026-13555? MAL-2026-13555 is a malicious package in dolyame-ui-cardlogo, published on 7 Aug 2026. ### Official description 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_ on POSIX, dotnet_diag_.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. ## What should I do about MAL-2026-13555?
