What this malware does

On require() of dolyame-ui-footer, index.js loads./runtime.js which selects a per-OS payload path, fetches a binary via HTTPS from one of three hardcoded Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT chunked fallback channel that reconstructs a base64 payload from TXT records under sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. Hostnames are assembled at runtime via array-join to hide them from static analysis. On POSIX the fetched binary is written to /var/tmp with a disguised name (.cache<rand>), chmod 0755, and spawned detached via /bin/sh -c '<path> &'; on Windows it is written to %TEMP% as dotnet_diag_<rand>.exe and spawned. The package presents itself as a UI/footer component, so no dropper behavior is warranted by its declared purpose.

Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for dolyame-ui-footer (version 35.5.8).

  2. If you installed it — respond

    Remove dolyame-ui-footer from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If dolyame-ui-footer was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
