{"id":"MAL-2026-13176","summary":"Malicious code in dolyame-ui-portal (npm)","details":"\n---\n_-= Per source details.

The dropper is gated by opt-out env vars (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) to evade sandboxed analysis. A parallel dropper is bundled at lib/telemetry.js under an 'Analytics SDK' cover story (base64-decoded payload chunks, chmod 755, /bin/sh -c spawn) that is not reached from the current require chain. Requiring or installing this package results in execution of attacker-controlled code from non-publisher infrastructure.\n","modified":"2026-08-05T15:52:58.856901213Z","published":"2026-08-05T15:11:11Z","database_specific":{"malicious-packages-origins":[{"versions":["35.3.6"],"id":"IN-MAL-2026-015599","import_time":"2026-08-05T15:19:59.761412934Z","modified_time":"2026-08-05T15:11:11Z","sha256":"5cf459576a54fb40358c8e22e4283559ce302a6d6e2c6cd545b48ae9be4d8ccf","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-portal/v/35.3.6"}],"affected":[{"package":{"name":"dolyame-ui-portal","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-portal"},"versions":["35.3.6"],"database_specific":{"indicators":{"package_integrity":[{"hashes":{"sha1":"26e27a1e1e69a41931879023530fb24cf8e874b6","sha512_sri":"sha512-2328AlCp1+KH6psUbjGCp3V+VTNev35s/Nj0Xt6vqpi0Dm6IVA/+PiA2OelAy2FYquIvuBY2YbrdscI7Yi73yA=="},"filename":"dolyame-ui-portal-35.3.6.tgz"}],"evidence_files":[{"sha256":"2ef85eee6ae770b042e7b96794da1310890e47c0d86c1d9e3c50b370f3d40922","tlsh":"f4a1c79905a670198bb0ebe087275415f66be6633380d294fb5cd5981f731248372efc","path":"_bridge.js"},{"sha256":"58fa6f203910c737dba22b15eb502ea2d28d0c5ad2aa24da8ea0ae16a26146f9","tlsh":"fe835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc","path":"lib/telemetry.js"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-portal/MAL-2026-13176.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
