# MAL-2026-10508: Malicious code in nodemon-elint (npm)


- **Type:** Malicious package

## What is MAL-2026-10508?

MAL-2026-10508 is a malicious package in nodemon-elint, published on 13 Jul 2026. 

### Official description

nodemon-elint@3.1.13 copies the source tree, README, author metadata, and homepage of the legitimate `nodemon` package but is published under a confusable name. Its package.json declares a runtime dependency on `type-elint@^3.3.7`, which is not required or imported by any file under lib/ and has no documented purpose in the package. Installing nodemon-elint therefore causes npm to resolve and install `type-elint` into the installer's dependency tree, where any install-time lifecycle scripts or require-time side effects in that sibling package execute on the installer's machine. The package.json also lists `chai@^4.4.1` — a test assertion library — under `dependencies` rather than `devDependencies`, with no `require('chai')` anywhere in lib/, an additional anomalous production dependency inconsistent with upstream nodemon. The pattern (name-confusion wrapper of a popular package + undocumented, unused sibling dependency whose name mirrors the typosquat scheme) is a dependency-chain drop: the wrapper itself contains no visible payload, but installing it pulls in attacker-controlled code via the forced dependency.

## What should I do about MAL-2026-10508?

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