The main entry (index.js) is empty (module.exports = {}); the only functional code is a preinstall script (callback.js) that runs automatically on npm install. On install, the script reads os.hostname(), os.userInfo().username, process.cwd(), npm_config_registry, and CI repository-identifier 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) and issues an HTTP GET to http://75.119.137.232:31337/depconfuse with those values as query parameters. The 9999.0.0 version, empty module body, hardcoded bare-IP over plaintext HTTP, and reporting of the configured npm registry plus CI repo slug are the canonical dependency-confusion reconnaissance shape used to identify internal build systems that mistakenly resolved a private package name to the public registry.\n","affected":[{"package":{"ecosystem":"npm","name":"jquery.ui.core"},"versions":["9999.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"callback.js","sha256":"cf163c553edd3c162c2e3b4b5f7ed8f52583c15a87a0e9dde389a662bfb0da1b","tlsh":"e5117bb9c68c0c3409c2178079686c5eb8fbe292338294917f2d71d26bb227046b71bd"},{"path":"package.json","sha256":"6291edfd58c20bfdea18ba776099c91cecd6ab6a8b3846cfb8086d555224fef9","tlsh":"49d09730aa2248233cd8efd30c2b098600338e2b050878092b87801d06a826728ff28d"}],"package_integrity":[{"filename":"jquery.ui.core-9999.0.0.tgz","hashes":{"sha1":"f16cc864d80931969dc37a8071d22ee2b65198aa","sha512_sri":"sha512-/UlePJPTU2W8/qAWnZDAuHroPF/bjxH/rGJGO0t/OHjKtwJPQtBBtfZuBjtL/OlpgxAMJakx28bJUOh2XT8Kbw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/jquery.ui.core/v/9999.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-014875","import_time":"2026-08-05T13:08:52.397793272Z","modified_time":"2026-08-05T13:05:06Z","sha256":"0fe5bc94d3ac40b31064d4dad8125dc959fdc3559785cdbeb03de2cc16c147ac","source":"amazon-inspector","versions":["9999.0.0"]}]}}
