# MAL-2026-12032: Malicious code in add-two-numbers-x7q9m (npm)


- **Type:** Malicious package
- **Package:** `add-two-numbers-x7q9m` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-12032?

MAL-2026-12032 is a malicious package in add-two-numbers-x7q9m, published on 5 Aug 2026. 

### Official description

The package advertises itself as a trivial 'add two numbers' utility but its preinstall lifecycle script enumerates the installer's Desktop directory, reads.txt files, applies a regex (/npm_[A-Za-z0-9_-]+/) to extract npm authentication tokens, and transmits any match as a query parameter to the hardcoded endpoint https://lively-bird-15.webhook.cool. This runs automatically on `npm install`. The behavior has no relation to the package's advertised arithmetic functionality, and the random name suffix is consistent with a disposable malicious-publish account. Harvested npm tokens enable registry account takeover and downstream supply-chain propagation via the victim's publish rights.

## What should I do about MAL-2026-12032?

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