The fetched bytes are written to /var/tmp/.cache_\u003chex\u003e on Unix or %TEMP%\\dotnet_diag_\u003chex\u003e.exe on Windows, chmodded 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. The masquerade filenames (dotnet_diag,.cache_), runtime hostname assembly, and DNS-TXT alternate delivery channel are anti-analysis mechanisms paired with the dropper. Installing or requiring the package auto-executes attacker-controlled code on the installer's machine.\n","modified":"2026-08-05T16:50:42.354495618Z","published":"2026-08-05T15:25:22Z","database_specific":{"malicious-packages-origins":[{"versions":["35.6.3"],"id":"IN-MAL-2026-015691","import_time":"2026-08-05T16:13:32.834112898Z","modified_time":"2026-08-05T15:25:22Z","sha256":"c5b6f75040edc2a67f6c4912c7b8ff63ec6bd8dbd35c235bd3787ea24f52d4a2","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-boxy-desktop-bnpl-card-panel/v/35.6.3"}],"affected":[{"package":{"name":"dolyame-boxy-desktop-bnpl-card-panel","ecosystem":"npm","purl":"pkg:npm/dolyame-boxy-desktop-bnpl-card-panel"},"versions":["35.6.3"],"database_specific":{"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-boxy-desktop-bnpl-card-panel/MAL-2026-13302.json","indicators":{"evidence_files":[{"sha256":"83047c51cabdbbdbb210fa756031c5407073a01ab0d66811d0d800b4c7e1fa2b","tlsh":"90a1b79a16a9701887b0abe48a27442af65bf3633780c1d4f76c99d40f725248372efc","path":"_polyfill.js"}],"package_integrity":[{"filename":"dolyame-boxy-desktop-bnpl-card-panel-35.6.3.tgz","hashes":{"sha1":"32ee1cbbfff786ca46cc13dacdb09c1a31d15fd3","sha512_sri":"sha512-/ADv0h5RIrscU4t9gHM7U71CPcKK0iR3VHrEJL9CALEmj5poXJIOWe7HrdlxTCo7wRjQh31X22qCSVKMVU1bOQ=="}}]}}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
