This executes attacker-controlled JavaScript with full `require` access under the installer's Node process. A base64-encoded backup endpoint and secret header key are stored in `lib/const.js` (decoding to a second jsonkeeper.com paste URL with an `x-secret-key` header), providing a redundant delivery channel. Because jsonkeeper.com is a mutable public paste site, the served payload can be changed at any moment. The logger API is a cover story for the dropper.\n","affected":[{"package":{"ecosystem":"npm","name":"notifier-log"},"versions":["1.3.5"],"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":"lib/caller.js","sha256":"c94c68398967a72596733d62b40d3b2df9490056a3b25bfd96333d0a88d84624","tlsh":"e701cb8f30fd101c019122e66b1fe4327010e85b390ae4d4374c87521ffa5aeaa53ede"},{"path":"index.js","sha256":"32e82853dd646aac388b78f868241267a5e6483d847df3d4c843f8100590d469","tlsh":"30213f8175f111480658d9c8b569e5363ce3c4377207b9b0e9ecb7862bcf20c0272ad7"},{"path":"lib/const.js","sha256":"9879ffb0bf61edef7e9b90ddc5fac9770c514c0cdecd9a07b15e8a677e6f8f74","tlsh":"8ac08c8351e4a89704301773610ca995f2a1d26f0c840b0331f594844a396a93840fbb"}],"package_integrity":[{"filename":"notifier-log-1.3.5.tgz","hashes":{"sha1":"96b24e2f513daab0bd05464190d041c7dffe4a38","sha512_sri":"sha512-mrBngV/OZyxmTEc/GS90RuK3DAKy5K7tS3tfPR9mYVAsQwY2lhqBFFSuMVqDSRFJIoHCh/UiuDdjfb0AUV1fHQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/notifier-log/v/1.3.5"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-009649","import_time":"2026-07-10T17:10:14.265302954Z","modified_time":"2026-07-10T16:46:36Z","sha256":"f4c2346bef8105dc24079ee47eb8cd65dbb92f7dbbd6d17ac0c576646878298c","source":"amazon-inspector","versions":["1.3.5"]}]}}
