The collected data is JSON-serialized, base64url-encoded, chunked into DNS label form, and exfiltrated to a hardcoded third-party out-of-band collector at *.oob.lyomeri.com via both a dns.lookup() call and an HTTP GET to easypanel-app.daco3v4q6f49egu1ds1gwjnsjb88s5kcp.oob.lyomeri.com. The name mimics the legitimate Easypanel project and the shape (preinstall + host/username/cwd + OOB DNS+HTTP beacon to a per-package subdomain) is a dependency-confusion reconnaissance beacon, disclosing installer identity and internal-package-name existence to a third party regardless of any 'benign canary' self-label.\n","modified":"2026-09-04T04:30:06.563643347Z","published":"2026-09-04T03:45:53Z","database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-019453","import_time":"2026-09-04T04:21:20.972556467Z","modified_time":"2026-09-04T03:45:53Z","sha256":"2744a6f0dfde1930ab560731e54cb8a1e1c8dc61a2072705498ddcaa6dd1a592","source":"amazon-inspector","versions":["1.0.0"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/easypanel-app/v/1.0.0"}],"affected":[{"package":{"name":"easypanel-app","ecosystem":"npm","purl":"pkg:npm/easypanel-app"},"versions":["1.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/easypanel-app/MAL-2026-15895.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"tlsh":"3e1167b0c260527c016061c4645a46b281b7dfd130e2c9d0682a26405fd22a30bb38fe","path":"preinstall.js","sha256":"78185239d223a9ee3a81fc6eb0dafcdc28723c7d4badac69ef74e61d66958c3c"}],"package_integrity":[{"hashes":{"sha1":"f213b624c672bbdac89aa8a6a260bdb3764da7f6","sha512_sri":"sha512-64qt+m2CLZ9a55lNfv0U41ZjXZrrPvG3gVAVXdJCVcKNw9zYIyzGaaU3Y3uYv4O6n6e9Z+DgyvEox7NVw/U30A=="},"filename":"easypanel-app-1.0.0.tgz"}]}}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
