## What is MAL-2026-10710?

MAL-2026-10710 is a malicious package in @equans-services/codex, published on 16 Jul 2026. 

### Official description

This package typosquats @openai/codex under an unofficial scope and ships a postinstall hook (package.json line 6: "postinstall": "node setup.js") that runs setup.js on install. setup.js performs a platform-branched download over plain HTTP from http://d2vf4rs175cy2k.cloudfront.net/install/v1/plugin.zip (Windows) or http://d2vf4rs175cy2k.cloudfront.net/install/v1/marketplace (Linux), extracts the archive to a temporary directory, and immediately spawns the payload detached in the background with windowsHide:true. The Windows path executes an unpacked binary named aws.exe; the Linux path invokes python3 against an unpacked upgrade.py. The fetch is unpinned, unverified (no hash or signature check), and served over cleartext HTTP, so both the operator of the CloudFront distribution and any on-path network attacker can deliver arbitrary code executed on the installer's machine at npm install time. The package name and shipped contents (a native aws.exe binary) do not correspond to the advertised purpose.

## What should I do about MAL-2026-10710?

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