The file also references 'ping' command invocations (lines 3, 83, 92) consistent with host reconnaissance. The destination URL is a placeholder template string ('REPLACE-WITH-YOUR-BEACON.example'), indicating this is either a published-by-mistake attack template or a proof-of-concept beacon stub — either way the structural shape (env-var read + POST to hardcoded non-publisher endpoint) is an installer-data exfiltration pattern with no legitimate purpose. Package name (under @djessicatony scope, suffix 'canary', version 0.0.1) and the placeholder C2 are consistent with throwaway test-publish of malicious tooling.\n","modified":"2026-05-26T06:01:47.438369734Z","published":"2026-05-21T00:52:43Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-05-21T00:52:43Z","sha256":"a504172fe0e456bd96cf7b4f9a6b6dda65dee7bd573833bbf5963b0be7a05ae8","source":"amazon-inspector","versions":["0.0.1"],"id":"IN-MAL-2026-003664","import_time":"2026-05-26T05:51:04.167078673Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@djessicatony/folk-mcp-canary/v/0.0.1"}],"affected":[{"package":{"name":"@djessicatony/folk-mcp-canary","ecosystem":"npm","purl":"pkg:npm/%40djessicatony%2Ffolk-mcp-canary"},"versions":["0.0.1"],"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":"index.js","sha256":"b13155b60f68a8f4ae5f2b10f45ef5318a50f9a5de91d451760e9f0de1f33027","tlsh":"4461b412a4b751ba03ea1084591b521667fc810b3b28b4b9be9cc2491fce3ad43b17cf"}],"package_integrity":[{"filename":"folk-mcp-canary-0.0.1.tgz","hashes":{"sha1":"1048056aca5292fe1d8fd1f6502ee5ce2906865b","sha512_sri":"sha512-hOzUJEFUegjeH7pluD5cJPXfJq9lncqxfZJkj5Oh9Dp6DThOrTuWAHqUIFOhVLzppHqe1zi4AYD9k0SDH5RO8w=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@djessicatony/folk-mcp-canary/MAL-2026-4382.json"}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["actran@amazon.com"],"type":"FINDER"}]}
