Endpoint hostnames are obfuscated by splitting them across string arrays joined at runtime to defeat static scanners. A DNS-TXT fallback channel under sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru retrieves base64-encoded payload bytes across numbered TXT records and follows the same write-and-execute path, providing redundant covert delivery when HTTP egress is filtered. A TTL stamp file provides persistence between invocations. The package's advertised name bears no relation to the actual behavior.\n","affected":[{"package":{"ecosystem":"npm","name":"checkout-molecule-mobile-status-sheet"},"versions":["35.7.9"],"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":"521ca0d54ebf6cc2ef6feff6e67730440ab8ac37ec81a9357a4276ff54a92c49","tlsh":"42a1849a1166301947b0dbe48b174416f65bf6633380c284fa6ca9945f77228c2b2efc"}],"package_integrity":[{"filename":"checkout-molecule-mobile-status-sheet-35.7.9.tgz","hashes":{"sha1":"c9320122738c6479085611308e2c4895a4a9dca2","sha512_sri":"sha512-2hkBPnG3lrHJnxTuXP+VzqHQOpq/HmJDpcPIZifuZIGEawdvzlRA3T2nFaBkaCE9m57KOdWVLGkY0M++gbdaVQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/checkout-molecule-mobile-status-sheet/v/35.7.9"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015189","import_time":"2026-08-05T14:20:11.218326004Z","modified_time":"2026-08-05T14:09:38Z","sha256":"d49254998829dd2e5809cd78290939f76e37c2c82dcb75d4331703522b95adb0","source":"amazon-inspector","versions":["35.7.9"]}]}}
