If those origins are unreachable, it falls back to a DNS-TXT-based delivery channel that reassembles a base64-encoded payload from numbered subdomains under *.dl.wel1.ru. The fetched binary is written to /tmp or %TEMP% under a disguised name (e.g. dotnet_diag_<rand>.exe or.cache_<rand>), chmodded 0755, and spawned detached via /bin/sh -c or cmd /c start. A TTL cache file (/tmp/.analytics_state) suppresses re-detonation on subsequent installs. The package name resembles a legitimate forms/cards library but ships no matching functionality; its only import-time effect is dropper execution.\n","affected":[{"package":{"ecosystem":"npm","name":"cards-forms-cards-core-clone"},"versions":["35.3.2"],"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":"_runtime.js","sha256":"35703c454c3d5298b24df675ed558e057e63193b33bfb063bffacd25f942170e","tlsh":"8fa1979a166671088bb0dbe4ca274416f65bf6633780c2d4f79ca5985fb31244372efc"}],"package_integrity":[{"filename":"cards-forms-cards-core-clone-35.3.2.tgz","hashes":{"sha1":"7dcdd4ee4e30136bba54f0169ddfbb7de015cc79","sha512_sri":"sha512-LkKunPujvYuvQKXyzhrx59FJryAzHggGXACScYekvoUNNziUzgjwDTAsh1MLlT2lyiCUcNOsmDPM693LI08qUw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/cards-forms-cards-core-clone/v/35.3.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015245","import_time":"2026-08-05T14:20:16.205362206Z","modified_time":"2026-08-05T14:17:57Z","sha256":"9d987094f38a49c0bb9ae5329e3ff47d97489ee5af348ebc7e056e752cffc1fb","source":"amazon-inspector","versions":["35.3.2"]}]}}
