## What is MAL-2026-13141?

MAL-2026-13141 is a malicious package in dolyame-ui-carousel, published on 5 Aug 2026. 

### Official description

On require of the package's main entry, _shim.js selects a platform-specific payload path and downloads a native binary from one of three Cloudflare Workers hosts whose names are assembled by string-array joins to evade static matching: oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, and oob-worker.cf101-adf.workers.dev. A DNS TXT chunked-base64 covert-channel fallback is implemented against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The fetched bytes are written to a hidden/disguised path in /tmp or %TEMP% (`.cache_<hex>` on Unix, `dotnet_diag_<hex>.exe` on Windows), chmod 0755, and spawned detached via `/bin/sh -c "<path> &"` or `cmd.exe /c start /b`. A stamp file gates re-execution. Cover-story identifiers such as `_NODES`, `analytics_state`, and `DISABLE_TELEMETRY` are used alongside the drop-and-exec logic. The package's declared purpose is a UI carousel component, which has no legitimate need to fetch and execute a native binary from anonymous workers.dev endpoints at import time.
