That file resolves the `os` and `dns` core modules indirectly through `module.constructor._load` with char-code-array names to avoid appearing in a normal `require` graph, then reads `os.userInfo().username`, `os.hostname()`, and the basename of `process.cwd()`. Those values are concatenated as DNS labels together with a hex-decoded destination domain and issued as a `dns.resolve4` query to a subdomain of `oob.algamil7x.xyz`, a DNS-based out-of-band exfiltration collector. The destination hostname and the core-module names are stored as char-code arrays and decoded at runtime, and the logic is split across helper files (b2e6f8.js/c3f7a9.js) under a `telemetry/probe` cover directory. Every `npm install` of this version therefore leaks the installing user's username, machine hostname, and working-directory name to an attacker-controlled domain, and the obfuscation shows the destination and API surface were deliberately hidden.\n","modified":"2026-09-22T22:30:06.169616255Z","published":"2026-09-22T21:50:08Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-09-22T21:50:08Z","sha256":"22c22841398a01b681136598baf046a8ad9ad9ef6d728899a0fbce056ff66369","source":"amazon-inspector","versions":["9.9.10"],"id":"IN-MAL-2026-020304","import_time":"2026-09-22T22:16:10.735613986Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@tvg-mar/tvg-promos-atomic-ui/v/9.9.10"}],"affected":[{"package":{"name":"@tvg-mar/tvg-promos-atomic-ui","ecosystem":"npm","purl":"pkg:npm/%40tvg-mar/tvg-promos-atomic-ui"},"versions":["9.9.10"],"database_specific":{"cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"indicators":{"evidence_files":[{"path":"runtime/support/telemetry/probe/impl.js","sha256":"279fe0af9fb71c815936f32b48457bd914fb954b0ff535a679f459407dcb3b89","tlsh":"6e119c5ab253d08f27d04699391c43e1482ec2d087dd10d1bbbc169ba2cd7914ad3a66"},{"path":"runtime/support/telemetry/probe/b2e6f8.js","sha256":"f7942b52b33a05f44ce43c1cc581fa1140cbbef03acdba961ade9f4a44cb03e1","tlsh":"73f0595166a3d19f77d69ac35f4190a0acb60a40b60ed0d5fa2c1bde00eeb13e9c54b0"}],"package_integrity":[{"filename":"tvg-promos-atomic-ui-9.9.10.tgz","hashes":{"sha1":"3030338e973149bc9ea3f0785bdc2e13fa253ab7","sha512_sri":"sha512-qxHhiUd+pWgbMwOqrVQWcKzV9MTJMNjdoFPQZxYrBKI417JwTtOuUp/9q0CdCNcIBbvBOVzm3sy67ZBc8zmC4Q=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@tvg-mar/tvg-promos-atomic-ui/MAL-2026-16415.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
