eslint-generate-release@99.9.1 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.
