A TTL lockfile named.analytics_state masquerades the persistence as telemetry. If HTTPS egress is blocked, _runtime.js falls back to a DNS-TXT covert channel under author-controlled subdomains (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), reassembling a base64 payload from numbered TXT records and executing it. No hash or signature verification is performed on the fetched bytes. The README describes only a trivial abstraction class, unrelated to any of the observed network or execution behavior.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-independent-bnpl-items"},"versions":["35.9.3"],"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":"f74965134839ef3506fe89df62fa375ea8bee3d257b8eeac349fcd2a46d058dd","tlsh":"cda1a69a16b670194bb09be4cb17441af65be6633380c294fb6ca5945f73124c372efc"}],"package_integrity":[{"filename":"bnpl-blocks-independent-bnpl-items-35.9.3.tgz","hashes":{"sha1":"0b3b4f61ce87f513688866ada56e1242e81f19eb","sha512_sri":"sha512-0snaK4fEAUcJlHyGK+7lJAfj7MxUd6hI2w6b93iFbU7UHHL79EKfIpcFcjuzrvhqQSG+mFYvU2Jo90tiWWXwiQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-independent-bnpl-items/v/35.9.3"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015422","import_time":"2026-08-05T15:19:50.540607161Z","modified_time":"2026-08-05T14:44:26Z","sha256":"9b068b10c6608e86812242f222c2936a85aae90776b6c71298731c16f8d7ae31","source":"amazon-inspector","versions":["35.9.3"]}]}}
