# MAL-2026-13107: Malicious code in bpm-foundation-common (npm)

## What is MAL-2026-13107?

MAL-2026-13107 is a malicious package in bpm-foundation-common, published on 5 Aug 2026. 

### Official description

On require('bpm-foundation-common'), index.js loads _loader.js which assembles C2 hostnames via runtime string-joining (e.g. ["oob-worker.","cf101-adf.","workers.d","ev"].join("")) with a DNS-TXT fallback to *.wel1.ru subdomains, downloads a platform-specific binary via https.get, writes it to /tmp/.cache_<hex> or %TEMP%/dotnet_diag_<hex>.exe, chmods 0755, and detached-spawns it via /bin/sh -c or cmd.exe. Dangerous API names are obfuscated (require("child_"+"process"), fs["chmod"+"Sync"]) to evade static analysis. A second dropper implementation with the same machinery (base64-decoded payload, /bin/sh -c spawn, chmod 0755) is bundled in lib/telemetry.js as an alternate payload path. The package has no documented native-build purpose that would justify fetching and executing a remote binary on require().

## What should I do about MAL-2026-13107?

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