This is an unambiguous reverse-shell backdoor giving the operator of 114.67.90.67 interactive command execution on the installer's machine. The package's advertised purpose (a string-manipulation utility, with `index.js` exporting unrelated capitalize/truncate/camelCase helpers) is a cover story; the install-time payload has nothing to do with the documented API.\n","affected":[{"package":{"ecosystem":"npm","name":"aikaf668897"},"versions":["1.0.3"],"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":"scripts/shell.js","sha256":"4dca6ea555f973adbe2bbe48498c7e4e320e4e13cc2d1c79c1b701ea40a9e998","tlsh":"8d11029451b5413b03bb8875899bc4323233d2137717e7c433dd105d9f838a81e9a5f0"},{"path":"scripts/postinstall.js","sha256":"20d2859a52b6f2bf12083b85a9332ef9c4be9dbdceab735e0789c7f15bb5a5c7","tlsh":"b8e0eb2ab3a2023cb1bac7c0bb5a33372a0b9700a3901020c9ae1067078739e81330e7"},{"path":"package.json","sha256":"cc916e827ab47e9a8524a5861646959fe36da7ff879cc36a8527e8de274d608e","tlsh":"f9f04c28ce205d3319d92a566da9540ab171580b0944bc187bd3801c5fae7bf54ff31d"}],"package_integrity":[{"filename":"aikaf668897-1.0.3.tgz","hashes":{"sha1":"449fcb5e099f7cd01cb5cd5babed9fd7a49f10ad","sha512_sri":"sha512-30t7vfWfeBc+LGuKmgiwwgMQ4f8gOczqMN0VcoOpdc6BKFhnuGvKGOOf05yjmH8mrAjd8PG61h9yMBJhJLzLng=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/aikaf668897/v/1.0.3"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-007084","import_time":"2026-06-19T15:41:56.029498538Z","modified_time":"2026-06-19T15:31:36Z","sha256":"450730a92143c06530923dacda588a17252ebc7edc9ddf71ff520446de5a3293","source":"amazon-inspector","versions":["1.0.3"]}]}}
