Destination hostnames and the child_process require are constructed by joining split string fragments to evade static analysis. If the HTTPS fetch fails, the fallback path reassembles a base64 payload from numbered DNS TXT records under *.dl.wel1.ru (c.\u003cdomain\u003e returns a chunk count, then 0.\u003cdomain\u003e..N.\u003cdomain\u003e are concatenated and base64-decoded) and executes the result the same way. The disguised filenames (dotnet_diag_*.exe,.cache_*,.analytics_state), anonymous Cloudflare Workers infrastructure, DNS covert channel, and opt-out gated only by DISABLE_TELEMETRY are all consistent with a hostile dropper delivering attacker-controlled code to the installer's machine at package load time.\n","modified":"2026-08-05T16:50:57.879577418Z","published":"2026-08-05T15:21:37Z","database_specific":{"malicious-packages-origins":[{"versions":["35.7.3"],"id":"IN-MAL-2026-015667","import_time":"2026-08-05T16:13:30.015585624Z","modified_time":"2026-08-05T15:21:37Z","sha256":"955003be540a21f5e2fd1a7a5a5586276a5cc7f733c09d1f5412250fe0035f1b","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-boxy-independent-bnpl-title/v/35.7.3"}],"affected":[{"package":{"name":"dolyame-boxy-independent-bnpl-title","ecosystem":"npm","purl":"pkg:npm/dolyame-boxy-independent-bnpl-title"},"versions":["35.7.3"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-boxy-independent-bnpl-title/MAL-2026-13334.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"sha256":"9b187e62af98489c399fe5fc50c22b26d24eeddfe1a67b070ccb9c6ef693fe2d","tlsh":"8fa1a5a617aa30188bb09be486174416f65ee6633381c6d4f75c69981fb3124c3b2efc","path":"setup.js"}],"package_integrity":[{"filename":"dolyame-boxy-independent-bnpl-title-35.7.3.tgz","hashes":{"sha512_sri":"sha512-JHtS5HWd9LjLzoYSzfQxQlI+92uKF9HeMToKzYoUnFP/fM9V5whL7QVfpRHE1LP1EI7aoAu2PyVGb5fhVfBf+A==","sha1":"8fc6ef9730537d01fbc34395ef33bdb90b24f4f6"}}]}}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
