When HTTPS retrieval fails, a DNS-based staging channel resolves TXT records on sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru — reading a chunk count from c.\u003cdomain\u003e and reconstructing a base64 payload from 0.\u003cdomain\u003e..N.\u003cdomain\u003e TXT records. The require of child_process is split as require(\"child_\"+\"process\") and the module is dressed up with an analytics_state cover-story marker resembling a Sentry-like telemetry SDK. Two redundant dropper paths execute on import: _adapter.js and the main entry lib/telemetry.js.\n","modified":"2026-08-08T01:05:02.511368959Z","published":"2026-08-08T00:43:42Z","database_specific":{"malicious-packages-origins":[{"versions":["35.8.1"],"id":"IN-MAL-2026-017141","import_time":"2026-08-08T00:53:06.344284251Z","modified_time":"2026-08-08T00:43:42Z","sha256":"dee413dd5d9f35d90594093501e52606a50dba9fcc61e73a7de489444b420229","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/sme-rko-finance-front-operations-feed-impl/v/35.8.1"}],"affected":[{"package":{"name":"sme-rko-finance-front-operations-feed-impl","ecosystem":"npm","purl":"pkg:npm/sme-rko-finance-front-operations-feed-impl"},"versions":["35.8.1"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/sme-rko-finance-front-operations-feed-impl/MAL-2026-13636.json","indicators":{"package_integrity":[{"filename":"sme-rko-finance-front-operations-feed-impl-35.8.1.tgz","hashes":{"sha512_sri":"sha512-3iwUwcIVV7qtrmYPu/6z6v1i+iqZCWM4D9W3PdAh1uLIv9Q6TfJiIOeX5tWQ6r6q2Efh1Kh+fG74x3aBc++OnQ==","sha1":"b1dfc2808613a9fd589998c139176bd4f2ebcb8e"}}],"evidence_files":[{"tlsh":"f5a1a55a16fa70180792a0d8852f5416b19ff65333c4e9d0fb4cb6989f9a13883b29fc","path":"_adapter.js","sha256":"be4dd88e76a2effcb1b422d78ab0f4357eed301eaa919a1877ad8177b4145fcf"},{"tlsh":"f573304966fb10214263b0685fbb40437635c4072a4aed5dba9c43ec9f8db3896f1fb9","path":"lib/telemetry.js","sha256":"59caef9d9ed4a896d11cb464ee07691a0e6f71b161af6e358825b1e3f7ebede3"}]},"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"}]}
