## What is MAL-2026-12451?

MAL-2026-12451 is a malicious package in statist-browser-typed-client-rubliq.platform.keycloak, published on 5 Aug 2026. 

### Official description

The package presents itself as a Keycloak typed client but on require() executes a binary dropper. index.js loads _adapter.js, which reconstructs destination hostnames from split string fragments joined via.join('') to hide them from static analysis, selects a platform-specific URL, and downloads a binary over HTTPS from Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev). The downloaded bytes are written to /tmp or the Windows Temp directory under disguised names (.analytics_state, dotnet_diag_*.exe,.cache_*), chmodded to 0755, and spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start. A DNS-TXT covert-channel fallback under subdomains of dl.well1.site (tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site) reassembles a base64-encoded binary from TXT record chunks when HTTPS fetch fails, feeding the same write+chmod+spawn chain. The child_process module name is constructed as require('child_' + 'process') and chmodSync is accessed as fs['chmod'+'Sync'] to further evade pattern matching. Environment variables DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, and DO_NOT_TRACK are checked to give the behavior a telemetry cover story. lib/telemetry.js contains a parallel dropper implementation with the same primitives, wrapped in 'Analytics SDK' comments. The package name resembles a legitimate Keycloak client but the shipped code performs installer-side arbitrary code execution rather than any Keycloak functionality.

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-2026-12451?

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