MAL-2026-12435 Malicious code in sc-geeksquad-core (npm)

[email protected] declares a preinstall script node callback.js that runs automatically on npm install. The script collects the installer's hostname (os.hostname()), OS username (os.userInfo().username), current working directory (process.cwd()), configured npm registry (npm_config_registry), and a set of CI repository-slug environment variables (GITHUB_REPOSITORY, CI_PROJECT_PATH, BUILD_REPOSITORY_NAME, BITBUCKET_REPO_FULL_NAME, TRAVIS_REPO_SLUG, DRONE_REPO, BUILDKITE_PIPELINE_SLUG, CIRCLE_PROJECT_REPONAME, JOB_NAME), then sends them via HTTP GET to the hardcoded bare-IP endpoint http://75.119.137.232:31337/depconfuse as query parameters. The placeholder version 9999.0.0 combined with a generic scoped-sounding name is the canonical dependency-confusion reconnaissance shape: the package is published to public npm to intercept internal-package name resolution and beacon back which private-namespace builds are vulnerable to substitution.

The OpenSSF Package Analysis project identified 'sc-geeksquad-core' @ 99.9.1 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.
