## What is MAL-2026-18060?

MAL-2026-18060 is a malicious package in codex-setup, published on 19 Oct 2026. 

### Official description

Package codex-setup@1.0.1 was examined and no behavior indicative of a supply-chain attack was observed. No lifecycle scripts fetching or executing remote content, no reads of installer secrets (such as ~/.aws, ~/.ssh, ~/.npmrc, browser profiles, or wallet stores), no environment-variable scraping, no hardcoded attacker-controlled network destinations, no obfuscated payloads, no backdoor or persistence mechanisms, and no silent-relay of caller-supplied data were identified. The package appears benign on the basis of the scanned contents.

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-2026-18060?

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