# MAL-2026-4661: Malicious code in react-tracked-tony (npm)

## What is MAL-2026-4661?

MAL-2026-4661 is a malicious package in react-tracked-tony, published on 20 May 2026. 

### Official description

react-tracked-tony impersonates the popular react-tracked package: package.json sets `name: react-tracked-tony`, `author: Daishi Kato`, and `homepage: https://react-tracked.js.org` (the real project's site), while the repository URL points at an unrelated user account (github.com/daltonchristiano060-gif/react-tracked-tony.git). The package re-exports the real react-tracked API to appear functional. On require/import in Node, endex.js fetches a JavaScript payload from https://almondco.online/api/droppers/38jmkse over HTTPS with TLS verification explicitly disabled (`rejectUnauthorized: false`) and executes the response body in-process via `new Function('require', text + tail)(require)`, handing the remote code full Node `require` access. Before fetching, endex.js enumerates ~20 cloud/CI/sandbox indicators (GitHub Actions, GitLab CI, CircleCI, Travis, Vercel, Netlify, Kubernetes, AWS Lambda/ECS/Batch, Azure, GCP Cloud Run/App Engine) and reads /sys/class/dmi/id/sys_vendor to detect Amazon/Google/Microsoft/QEMU/OpenStack hypervisors, aborting on match — a deliberate anti-analysis gate so the payload only fires on real developer/operator machines. Combination of typosquat + impersonated author metadata + import-time remote-code-exec from a non-publisher domain + TLS verification disabled + sandbox evasion is an unambiguous supply-chain attack.

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-2026-4661?

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