Advisory published Updated

Malicious code in dolyame-ui-toggle (npm)

MAL-2026-13196
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall dolyame-ui-toggle

What this malware does

Requiring the package loads ext.js, which downloads a platform-specific binary from obfuscated *.workers.dev endpoints (with a DNS-TXT base64 fallback via *.dl.wel1.ru), writes it to /var/tmp or %TEMP% under disguised names such as '.cache<tag>' or 'dotnet_diag_<tag>.exe', chmods it 0755, and spawns it detached via '/bin/sh -c' or 'cmd.exe /c start /b'. Endpoint hostnames and resolver domains are constructed by joining fragment arrays to evade string scans, and the dropped file names impersonate telemetry/diagnostic artifacts. The package's declared purpose is a trivial UI toggle; the fetched, unpinned, unverified binary is unrelated to that purpose. The result is arbitrary attacker-controlled code execution on any machine that installs or imports this version.

Detection & response playbook

Typosquat
  1. Find it

    Search your lockfiles and build artifacts for dolyame-ui-toggle (version 35.4.1).

  2. If you installed it — respond

    dolyame-ui-toggle is a typosquat — you almost certainly intended a legitimately-named package. Remove dolyame-ui-toggle, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

  3. Did it already run?

    If dolyame-ui-toggle 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.
