Both _compat.js and lib/telemetry.js implement the fetch-write-chmod-spawn chain; lib/telemetry.js additionally assembles the payload from base64 chunks. Sinks and hostnames are constructed via array.join('') string-splitting (e.g. ['sdk.dl.','wel1.','ru'].join(''), require('child_' + 'process'), fs['chmod'+'Sync']) to defeat static scanners, while comments frame the behavior as analytics/telemetry. The delivered bytes are opaque, unpinned, and unverified, and the workers.dev / wel1.ru destinations are anonymous infrastructure unrelated to any documented publisher.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-iconloaderhoc"},"versions":["35.8.1"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"_compat.js","sha256":"9317fd2cad89807d51eda00a0805b050d3088e006589a8bf6cc69b42e1e43591","tlsh":"b7a1a55a16fa70180792e5d9841f8816b09af98337c5d8c4fb4c66948feb128c3b29fc"},{"path":"lib/telemetry.js","sha256":"838384c08f39772cde0881f9d6b9beb0c5f6e74b79b2e081d109668b8d8c99b4","tlsh":"f573304966fb1021826370685fbb40437635c4072a4aed5dba9c43ec9f8db3896f1fb9"}],"package_integrity":[{"filename":"dolyame-ui-iconloaderhoc-35.8.1.tgz","hashes":{"sha1":"d03f6ca1cf9550738ca6d8debdfeda4cab486c45","sha512_sri":"sha512-nEd+7Mk+zwuhDKYQcuso4nfil6KFLUfZSzR8tYlTry/MkOr+/XIeDDkzW7iMlQE3UJbqHaTAlfZIUXMm6n00Kw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-iconloaderhoc/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016889","import_time":"2026-08-07T12:23:25.866363301Z","modified_time":"2026-08-07T12:13:18Z","sha256":"812cef02743987901661dc22ace6c19fee82977c4bb73b05ee046698ad603932","source":"amazon-inspector","versions":["35.8.1"]}]}}
