The collected data is base64-encoded and sent via HTTP GET to a hardcoded Burp Collaborator subdomain at pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com/z?d=<base64>. The package presents itself as an array-sort utility but ships no such functionality; index.js contains unrelated color helper code. The behavior is credential and secret harvesting targeted at CI runners and cloud workloads.\n\n## Source: ossf-package-analysis (6cade78851ee1586c3bbf22b8c1393e0c2f8e51ac6c8496aaaf50cda425807cc)\nThe OpenSSF Package Analysis project identified 'array-sort-helper' @ 1.0.0 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n\n- The package executes one or more commands associated with malicious behavior.\n","affected":[{"package":{"name":"array-sort-helper","ecosystem":"npm"},"versions":["1.0.0"],"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":"postinstall.js","sha256":"5826f6884581fbfa40d0793ff4c4b6f3b4e5e0a704bfd87bf7c4e3ec274b2ec9","tlsh":"8931fbf8b56ded72304dc5f8b75d14053846eaeb58e4ff74281b8875008e48420a9136"}],"package_integrity":[{"filename":"array-sort-helper-1.0.0.tgz","hashes":{"sha1":"a52fff557272de9c6f23741b8e82215d59829c17","sha512_sri":"sha512-uewYf02Qe0eC199lHmvlLED8zwETay5vykvKfCsF/Flb274TcWKpfLO6ijmdpGfNKl5atDcV0bBaP7rewR/E4g=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/array-sort-helper/v/1.0.0"}],"database_specific":{"malicious-packages-origins":[{"import_time":"2026-07-28T08:22:36.63728308Z","modified_time":"2026-07-28T08:17:41Z","sha256":"6cade78851ee1586c3bbf22b8c1393e0c2f8e51ac6c8496aaaf50cda425807cc","source":"ossf-package-analysis","versions":["1.0.0"]},{"id":"IN-MAL-2026-011045","import_time":"2026-08-04T21:33:14.941094528Z","modified_time":"2026-08-04T21:24:32Z","sha256":"2c18cc0d6d922eb6bbfcb565415772dbd0bb246ca7595f18afe1f87f2f6c1a33","source":"amazon-inspector","versions":["1.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"OpenSSF: Package Analysis","contact":["https://github.com/ossf/package-analysis","https://openssf.slack.com/channels/package_analysis"],"type":"FINDER"}]}
