## What is MAL-2026-12132?

MAL-2026-12132 is a malicious package in accounts-ddos-shield, published on 5 Aug 2026. 

### Official description

On require of the package, _helpers.js selects a platform-specific payload path and downloads an opaque binary from one of several Cloudflare Workers hosts whose names are assembled from split string fragments via Array.join to hide the destinations from static inspection (oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev), with a DNS TXT reassembly fallback under tin/tina/ldr/win.dl.well1.site. The fetched bytes are written to /var/tmp or %TEMP% under decoy names impersonating Microsoft diagnostics (dotnet_diag_<hex>.exe,.cache_<hex>,.analytics_state), chmod 0755 on POSIX, and spawned detached via /bin/sh or cmd.exe start. The module is labeled _helpers.js with telemetry-framing comments while it stages and executes a remote binary. The package name presents as a DDoS-protection utility, but no such functionality is delivered — the sole effect of loading the module is to run attacker-controlled code on the installer's host.

## What should I do about MAL-2026-12132?
