On `npm install`, the preinstall script collects `os.hostname()`, `os.userInfo().username`, `process.cwd()`, `npm_config_registry`, and a sweep of CI repository-identifier environment variables (GitHub, GitLab, Azure, Bitbucket, Travis, Drone, Buildkite, Circle, Jenkins) and sends them as query-string parameters over plain HTTP to the hardcoded bare-IP endpoint http://75.119.137.232:31337/depconfuse. The 9999.0.0 version and empty main are consistent with a probe designed to outrank an internal `jquery.ui.tabs` package in mixed registry resolution and report back which organizations resolve the public name, exposing internal hostnames, usernames, working directories, and private repository slugs to an attacker-controlled host.\n","modified":"2026-08-05T13:35:34.265435241Z","published":"2026-08-05T13:05:29Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-08-05T13:08:52.603541643Z","modified_time":"2026-08-05T13:05:29Z","sha256":"50fc48e6d03705244cf78a2f2ee23c6ffe5a91a64f98d23d6a31f94557bf0d84","source":"amazon-inspector","versions":["9999.0.0"],"id":"IN-MAL-2026-014878"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/jquery.ui.tabs/v/9999.0.0"}],"affected":[{"package":{"name":"jquery.ui.tabs","ecosystem":"npm","purl":"pkg:npm/jquery.ui.tabs"},"versions":["9999.0.0"],"database_specific":{"indicators":{"evidence_files":[{"tlsh":"0a119eb9c68c0d3409c2178479686c5eb8fbe29233c294917f2d71d26bb227046b75fd","path":"callback.js","sha256":"5ccd3bf1db0172f252cdfd3b160166e2f8f239f605763837796962fcca0a52bf"},{"sha256":"624ff5e65eefdb362b0f74243ac76a458aa69ed9ed018ba419af6e0199b4342f","tlsh":"4ed09730da2248233cd8ffd30c2a058600378f2b01087c092787901d45aca6728ff28d","path":"package.json"}],"package_integrity":[{"hashes":{"sha1":"8388f21713889797a7de8817c4dd6b59244d87f2","sha512_sri":"sha512-XG1sJa2grN7cdy2YvQN+dY1ho8wdK5B7+Xv8+r8qUKqUs/tXo4obh3tV//u6A4/YcwkqyD/iXsx/vDmOR1RJUw=="},"filename":"jquery.ui.tabs-9999.0.0.tgz"}]},"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/jquery.ui.tabs/MAL-2026-12395.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
