{"id":"MAL-2026-18689","summary":"Malicious code in loader-utils-kit (npm)","details":"loader-utils-kit ships lib/contract.js, byte-identical to the pino-testkit payload: an obfuscated module that decodes and evaluates code at load. It is a new name for the pino-testkit (MAL-2026-16484) campaign; the file hashes below match that record's evidence. The package presents itself as an ordinary utility, so the code runs on import or install without the user knowing.","modified":"2026-11-05T05:15:05.065079013Z","published":"2026-10-26T00:00:00Z","database_specific":{"iocs":{"urls":[],"domains":[],"files":[{"paths":["lib/contract.js"],"digests":{"sha256":"c6a9028513792f288fec1d7c217c55d9541d96d436cb119ef0553c3fd49d6c41"}}],"ips":[]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/loader-utils-kit"},{"type":"WEB","url":"https://osv.dev/vulnerability/MAL-2026-16484"}],"affected":[{"package":{"name":"loader-utils-kit","ecosystem":"npm","purl":"pkg:npm/loader-utils-kit"},"versions":["4.2.1","4.3.5"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/loader-utils-kit/MAL-2026-18689.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
