## What is MAL-2026-12452?

MAL-2026-12452 is a malicious package in statist-browser-typed-client-sme.platform.mobile.voip.common.events, published on 5 Aug 2026. 

### Official description

On require, _compat.js selects a platform-specific payload path and downloads an opaque binary from one of four Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev). Origin hostnames are assembled from split-string fragments joined at runtime to hide the destinations from static inspection. The fetched bytes are written to a hidden file staged as a system-artifact lookalike (dotnet_diag_<hex>.exe on Windows,.cache_<hex> on Unix) in /tmp or %TEMP%, chmod 0755, and executed via spawn("/bin/sh", ["-c", <path> + " &"], {detached:true, stdio:"ignore"}).unref() (or the cmd equivalent on Windows). If the HTTPS fetch fails, the loader falls back to a DNS TXT covert channel, querying subdomains under dl.well1.site (tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site) for base64-encoded payload chunks that are concatenated and executed the same way. The package advertises itself as a domain-event handler; the fetched executable content has no relationship to that stated purpose.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-12452?

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