{"id":"MAL-2026-13162","summary":"Malicious code in dolyame-ui-label (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (bdcede6d4d42bfed7f10577346b24e9af22655e50f8d454baab6f4999e6020f3)\ndolyame-ui-label 35.7.8 is not a UI component library. On require() of the package, index.js loads _helpers.js, which reconstructs C2 hostnames at runtime from split-string arrays (e.g. [\"oob\",\"-worker.cf102-baf.workers.dev\"].join(\"\") and ['sdk.dl.wel','1.','ru'].join(\"\")) to evade static inspection. It selects a platform-specific endpoint among oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, and oob-worker.cf103-070.workers.dev, with a DNS-TXT base64 fallback via sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru, downloads a native binary via https.get, writes it to /tmp/.cache_\u003crand\u003e on Unix or %TEMP%\\dotnet_diag_\u003crand\u003e.exe on Windows, chmods it 0755, and spawns it detached via /bin/sh -c or cmd. Cover-story comments frame the traffic as analytics/telemetry/CDN. The package's declared purpose (UI labels) has no legitimate need for a native binary drop, and the destinations are unrelated to any documented publisher, unpinned, and unverified.\n","modified":"2026-08-05T15:52:52.266763216Z","published":"2026-08-05T15:13:07Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-08-05T15:20:00.240963122Z","modified_time":"2026-08-05T15:13:07Z","sha256":"bdcede6d4d42bfed7f10577346b24e9af22655e50f8d454baab6f4999e6020f3","source":"amazon-inspector","versions":["35.7.8"],"id":"IN-MAL-2026-015612"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-label/v/35.7.8"}],"affected":[{"package":{"name":"dolyame-ui-label","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-label"},"versions":["35.7.8"],"database_specific":{"indicators":{"evidence_files":[{"path":"_helpers.js","sha256":"668f89a52279d7f4525cc2a0f288b0d06152a37aa586beb70f34e4e552617887","tlsh":"d5b1965b166a70184bb0ebe4c717541af65be2633780c2d8fb5c69981f7212483b2efc"}],"package_integrity":[{"filename":"dolyame-ui-label-35.7.8.tgz","hashes":{"sha1":"077565f246acba9c28763a32607549f54760ca3d","sha512_sri":"sha512-ie1PTBue5ZhynI5nujoWdBG6UACNAdcaWDwFa6XSl1Df995EJx0ncVTxjaBNI6B7/DRSReyTimr2VLRQZWHwCw=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-label/MAL-2026-13162.json","cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
