{"id":"MAL-2026-13335","summary":"Malicious code in dolyame-boxy-independent-bnpl-video (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (f3490fd11839adb1f5027facaf8046cd19e640fffdbf79d0684c91a565dd8303)\nOn require() of the package's main entry, index.js loads _adapter.js which performs OS/arch detection and fetches an opaque binary from string-split-obfuscated Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT chunked-base64 fallback via *.dl.wel1.ru (sdk.dl.wel1.ru). The retrieved bytes are written to /var/tmp or %TEMP% under decoy names (.cache_\u003chex\u003e, dotnet_diag_\u003chex\u003e.exe), chmod 0755, and spawned detached through /bin/sh -c or cmd.exe with stdio ignored (_adapter.js:118-124). Destination hostnames and the child_process module name are reassembled from split string literals at runtime (['sdk.dl','.wel1.','ru'].join(''); require('child_' + 'process')) with cover comments framing the code as 'telemetry/analytics'. A sibling module lib/telemetry.js (~81KB) mirrors the same fetch -\u003e base64-decode -\u003e chmod 0755 -\u003e /bin/sh spawn primitives as a companion payload. The delivery infrastructure, destination obfuscation, decoy filenames, and lack of any integrity check or publisher-matching source identify this as a supply-chain dropper rather than a legitimate runtime download.\n","modified":"2026-08-05T16:50:58.134985728Z","published":"2026-08-05T15:20:37Z","database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","versions":["35.4.4"],"id":"IN-MAL-2026-015661","import_time":"2026-08-05T16:13:29.435256618Z","modified_time":"2026-08-05T15:20:37Z","sha256":"f3490fd11839adb1f5027facaf8046cd19e640fffdbf79d0684c91a565dd8303"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-boxy-independent-bnpl-video/v/35.4.4"}],"affected":[{"package":{"name":"dolyame-boxy-independent-bnpl-video","ecosystem":"npm","purl":"pkg:npm/dolyame-boxy-independent-bnpl-video"},"versions":["35.4.4"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-boxy-independent-bnpl-video/MAL-2026-13335.json","cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"indicators":{"package_integrity":[{"filename":"dolyame-boxy-independent-bnpl-video-35.4.4.tgz","hashes":{"sha1":"0f42faa8698ac11f6aa422c15245da1b5db6323e","sha512_sri":"sha512-Wi7yLfI/zo+DpoYFuPD0XnBJBPBqFaCjc8VpDKGUnZRUml69Gc1QxYsa2grE0jtdqmhJ50R3ST5NW72km5nVKg=="}}],"evidence_files":[{"sha256":"c868e5d880ebf99f10558741f684a17820539e16263612ff3f6d13c37b0aec9c","tlsh":"c9a186aa11a670184bb0ebe4c7175416f556f6633780c198fb9c99985fb3124c2f2efc","path":"_adapter.js"},{"path":"lib/telemetry.js","sha256":"611c4dec0b990b3a0a2dbf2c69782c0660ffa5ba69fcc9206bb4d4c5de0ab9cd","tlsh":"55835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}]}}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
