Malicious package

eslint-generate-releasenpm

Advisory published Updated

eslint-generate-release is a confirmed malicious npm package (MAL-2026-13980) that typosquats a legitimate package to trick installs (malicious version 99.9.1). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in eslint-generate-release (npm)

MAL-2026-13980
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall eslint-generate-release

What this malware does

[email protected] is a hollow package whose index.js exports an empty object and whose only effect on install is dependency resolution. package.json declares a runtime dependency ltidisafe whose version specifier is not an npm-registry version but a direct HTTPS tarball URL: https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.6.3.tgz. On npm install, npm fetches and installs that off-registry tarball into node_modules, introducing code that never passed through the npm registry. The package name mimics the ESLint ecosystem and the 99.9.1 version is a version-squat pattern; combined with the empty main entry, the package functions purely as a smuggling wrapper for the URL-referenced payload.

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.

Detection & response playbook

Typosquat
  1. Find it

    Search your lockfiles and build artifacts for eslint-generate-release (version 99.9.1).

  2. If you installed it — respond

    eslint-generate-release is a typosquat — you almost certainly intended a legitimately-named package. Remove eslint-generate-release, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

  3. Did it already run?

    If eslint-generate-release was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. eslint-generate-release on npm has been identified as a malicious package (version 99.9.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
