# MAL-2026-13196: Malicious code in dolyame-ui-toggle (npm)

## What is MAL-2026-13196?

MAL-2026-13196 is a malicious package in dolyame-ui-toggle, published on 5 Aug 2026. 

### Official description

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.

## What should I do about MAL-2026-13196?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
