npm uninstall dolyame-ui-react-wrapper

What this malware does

On require, index.js loads helpers.js which runs setup() at module load. The setup routine reconstructs mirror hostnames at runtime by joining split string fragments (e.g. 'oob-worker.cf101-adf.workers.dev', 'oob-worker.cf100-416.workers.dev', 'oob-worker.cf103-070.workers.dev') and DNS-discovery domains ('sdk.dl.wel1.ru', 'ext.dl.wel1.ru', 'pkg.dl.wel1.ru', 'net.dl.wel1.ru') with a DNS TXT base64 fallback, downloads a platform-specific binary via https.get, writes it to /tmp or the Windows Temp directory under disguised names such as '.cache<hex>' and 'dotnet_diag_<hex>.exe', chmods it 0755, and spawns it detached through '/bin/sh -c' or 'cmd'. The package name presents as a UI React wrapper for an unrelated payments brand, unrelated to the actual behavior, and string obfuscation of hostnames serves only to defeat scanners.

Detection & response playbook

Malicious package

  1. Find it

    Search your lockfiles and build artifacts for dolyame-ui-react-wrapper (version 35.4.2).

  2. If you installed it — respond

    Remove dolyame-ui-react-wrapper 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-react-wrapper 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.

Frequently asked questions
