## What is MAL-2026-18206?

MAL-2026-18206 is a malicious package in @ecg-internal/adobe-dmp-js, published on 23 Oct 2026. 

### Official description

Package uses the `@ecg-internal/*` scope (resembling an internal namespace) and ships a minimal stub whose only effect is to beacon host identifiers to a hardcoded bare-IP endpoint. `package.json` declares a `postinstall` that runs `beacon.cjs`, which POSTs JSON containing `os.hostname()`, `__dirname` (install path), `process.cwd()`, Node version, and the package name to `http://185.158.107.175:8787/_ah/dc` over plain HTTP. The package `main` (`index.js`) also calls `require('./beacon.cjs').fire()` at top level, so the same callback fires on every `require`/`import`. `index.js` exports a `Proxy` no-op so property accesses on the module silently return functions, allowing consumer build pipelines to continue without errors and masking that the package is a stub. The hardcoded bare-IP destination over plain HTTP, unrelated to any legitimate Adobe or ECG infrastructure, together with the internal-looking scope and inert functional surface, is the canonical dependency-confusion reconnaissance payload used to map which victims resolved an attacker-published public package in place of a private internal one.

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-2026-18206?

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