A DNS-TXT covert channel under c.*.dl.wel1.ru reconstructs a base64 payload as fallback delivery. Execution is gated once per host via a /tmp/.analytics_state stamp. The delivery infrastructure is not the package publisher's, the fetched bytes are unsigned and unverified, the destination path and filename are disguised, and execution is detached — the shape is a supply-chain dropper, not a legitimate runtime install.\n","modified":"2026-08-05T15:51:38.153916800Z","published":"2026-08-05T14:37:59Z","database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015378","import_time":"2026-08-05T15:19:48.123483382Z","modified_time":"2026-08-05T14:37:59Z","sha256":"d7f199feae1ae38b3dfd2c94cf56ad56ef7ef0fe4e0172a64ef76ddf401bcbcb","source":"amazon-inspector","versions":["35.5.3"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-mobile-bnpl-reviews/v/35.5.3"}],"affected":[{"package":{"name":"bnpl-blocks-mobile-bnpl-reviews","ecosystem":"npm","purl":"pkg:npm/bnpl-blocks-mobile-bnpl-reviews"},"versions":["35.5.3"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/bnpl-blocks-mobile-bnpl-reviews/MAL-2026-13003.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"package_integrity":[{"hashes":{"sha512_sri":"sha512-Gf6dAcBByq0PDGffWcWJYDuWAb49RWTiy1sqitWMGr/kmQMDKOTSyNXBuqoeh/WJ5uswNFHgoYJ8bokX3c3ktw==","sha1":"02580d29824f934f3d3dfb3adf6713b9c85c5e58"},"filename":"bnpl-blocks-mobile-bnpl-reviews-35.5.3.tgz"}],"evidence_files":[{"tlsh":"29a1a9961666701887b0ebe4c7275816f65bf6633780c294f75ca9981f7322483b2efc","path":"_bootstrap.js","sha256":"8ed7060c2c89b5bb4e154b8dcd2729954342e783f7837f455724a64c1bdaf87f"}]}}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
