The payload is written to /var/tmp or %TEMP% under a masqueraded name (.cache_*, dotnet_diag_*.exe), chmod'd 0o755, and spawned detached via spawn('/bin/sh', ['-c', fp+' &']) or spawn('cmd',...). A secondary DNS-TXT covert channel over sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru serves base64-chunked payload as fallback (c.\u003cdomain\u003e yields chunk count, i.\u003cdomain\u003e returns base64 chunks decoded with Buffer.from(...,'base64')). Execution is gated by a filesystem stamp and env vars framed as telemetry opt-outs. The package is advertised as data-store bindings and has no legitimate need to fetch and execute a native binary from anonymous workers.dev hosts at require time.\n","modified":"2026-08-05T16:50:36.580127675Z","published":"2026-08-05T15:27:32Z","database_specific":{"malicious-packages-origins":[{"versions":["35.9.5"],"id":"IN-MAL-2026-015706","import_time":"2026-08-05T16:13:34.513112768Z","modified_time":"2026-08-05T15:27:32Z","sha256":"bdce627f475557b2376352c5dbc9cc8970949fdccef36073a4665c01fe4af92f","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-boxy-atom-bnpl-store-button-set/v/35.9.5"}],"affected":[{"package":{"name":"dolyame-boxy-atom-bnpl-store-button-set","ecosystem":"npm","purl":"pkg:npm/dolyame-boxy-atom-bnpl-store-button-set"},"versions":["35.9.5"],"database_specific":{"indicators":{"evidence_files":[{"path":"_platform.js","sha256":"263fd0f8757aad893d9fa3863ce037369c5e506a2e3b503e0e4cbe33b93390c2","tlsh":"12a1875a126670188bb0ebe0c71b4816f65bf6533781c584fb9c65985fb36248372efc"}],"package_integrity":[{"filename":"dolyame-boxy-atom-bnpl-store-button-set-35.9.5.tgz","hashes":{"sha1":"78997e6a0c9f8e9b7ede60f842e662cb2e7148f4","sha512_sri":"sha512-8tS8IUB5xqMf3iCDVu+mByWE8E7HKOs/ub54dK1W+QCeVPrb++TbfVIJl/T0JNstWLRUifX65n8oA1s77C5rIQ=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-boxy-atom-bnpl-store-button-set/MAL-2026-13290.json","cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
