Destination hostnames are constructed by array-join (e.g., [\"oob-worker.cf100-416.workers.d\",\"ev\"].join(\"\")) to defeat static string scanning. If HTTPS fetch fails, the loader falls back to a DNS-TXT covert channel: it queries c.<domain> under *.dl.wel1.ru (sdk/ext/pkg/net) for a chunk count and reassembles base64 payload from numbered TXT records, executing the reassembled bytes identically. A mirrored copy of the dropper exists in lib/telemetry.js and additionally hides child_process via require(\"child_\"+\"process\"). The fetched binary is unpinned and unverified; content is attacker-controlled and executed with the installer's privileges.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-desktop-bnpl-navigation"},"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":"7920a69796dde41cc0a9d9883015ea915f9270d4fbc53d71e1be88af29fb74af","tlsh":"ffa187a516a570194bb0ebe0c71b9819f55af6633780c2c4f79c65885fb352483b2efc"}],"package_integrity":[{"filename":"bnpl-blocks-desktop-bnpl-navigation-35.3.2.tgz","hashes":{"sha1":"1797c981daef3719a09c965121538bbe9c097d4a","sha512_sri":"sha512-jAT34W6hdftwUiIyviqjLGwywf1pZWPn8btKEpbREJWk0ktPy/tn4kINoW1Qbi/T+QnB03M7Cl5SMqL74QB0CA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-desktop-bnpl-navigation/v/35.3.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015442","import_time":"2026-08-05T15:19:51.587629543Z","modified_time":"2026-08-05T14:47:25Z","sha256":"3e0ae14a5603433798af1dda72f0e9c1ae60505afa9205177c558c208d362b5e","source":"amazon-inspector","versions":["35.3.2"]}]}}
