Network destinations are hidden by array-joining fragmented substrings and require() is invoked as require('child_'+'process') to evade static matching. No integrity check, no consent prompt, and only an environment-variable opt-out. A dormant secondary dropper in lib/telemetry.js ships in the tarball with the same spawn/chmod/base64 shape framed as an analytics SDK, but is not reached from index.js in this version.\n","modified":"2026-08-05T15:52:36.386083320Z","published":"2026-08-05T15:17:42Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-08-05T15:20:01.295918963Z","modified_time":"2026-08-05T15:17:42Z","sha256":"9e5ba9319e9ab791d3944f19baaae57aac3c2d381bf03ccf736d8ae09a2ba4b6","source":"amazon-inspector","versions":["35.1.8"],"id":"IN-MAL-2026-015641"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-boxy-mobile-bnpl-text-block/v/35.1.8"}],"affected":[{"package":{"name":"dolyame-boxy-mobile-bnpl-text-block","ecosystem":"npm","purl":"pkg:npm/dolyame-boxy-mobile-bnpl-text-block"},"versions":["35.1.8"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-boxy-mobile-bnpl-text-block/MAL-2026-13128.json","indicators":{"evidence_files":[{"sha256":"da1ba2351f8ef32df51cf6c51c1afbd065f68180e4241c59f7bba2b2854f681c","tlsh":"9ba1a75a12a570194fb09be0c71b8815f95bfa6337818284f79ca5955fb312883b2efc","path":"_compat.js"},{"path":"lib/telemetry.js","sha256":"aaaeb418e57fc7d88938c6efc3f907752982119cc32429ed60f47496aa1e9d37","tlsh":"ad835055566a142186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"hashes":{"sha1":"b3a513fd28702061fc62b7f9c583389826c77d8e","sha512_sri":"sha512-d+k7woLyumcQfNeCrfq/3RhSyrdZ+eZKHeLagm99tUsDpP+afyVDimo58JXzCgqCbotF9Jnbt7mwPcqxlWXvFQ=="},"filename":"dolyame-boxy-mobile-bnpl-text-block-35.1.8.tgz"}]},"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
