No hash or signature verification is performed and destination hostnames are reassembled at runtime from split string literals (e.g. ['oob-worker.cf101-adf.wo','rk','ers','.de','v'].join('')) to evade static analysis. A marker file /tmp/.analytics_state throttles re-execution. A second, parallel dropper is shipped in lib/telemetry.js: it base64-decodes a payload, chmods 0755 and spawns /bin/sh -c <path> &, with disguised API access (fs['chmod'+'Sync'], require('child_'+'process')) framed as an 'Analytics SDK'. Both files exhibit the same fetch-write-chmod-spawn pattern.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-atom-bnpl-toggle"},"versions":["35.2.4"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"_platform.js","sha256":"0e5db4525932ea0c9b308a716539b9fca30efbf30aebb579822f7623e3fac9cd","tlsh":"25a1a55a166970188bb0d7e4c6178416f5abf6633381c2c4f79c65945f7312483b2efc"},{"path":"lib/telemetry.js","sha256":"6430c36644ccd537c279eb0e6316b2587c50a4d8bef3d8b2c50c9617fd11e4b1","tlsh":"0a835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"bnpl-blocks-atom-bnpl-toggle-35.2.4.tgz","hashes":{"sha1":"06861dd138eac62e280881db995770f8d86fbf8c","sha512_sri":"sha512-oTqKcq5k5pDKQCciYs3SGJX86hcBUzB+ZmzdbboX0NuHr1tvpD+XhgsGt9nrEwETgkz24cBDU3OQAK+He1foBg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-atom-bnpl-toggle/v/35.2.4"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015483","import_time":"2026-08-05T15:19:53.809168782Z","modified_time":"2026-08-05T14:53:22Z","sha256":"d9b4cea9f3ecb85954dffb42aac8b9869e662493ae87815a7feb8c293e398b79","source":"amazon-inspector","versions":["35.2.4"]}]}}
