The package ships no other functionality: package.json has an empty description, empty author, no repository, and the generic name `utils-style-engine`; the only shipped file besides the manifest is the beacon script. The shape is consistent with a dependency-confusion / reconnaissance probe.\n","affected":[{"package":{"ecosystem":"npm","name":"utils-style-engine"},"versions":["10.2.4"],"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":"0b11f117bb21140a7a6f707d67f5d82960593281ee144ee4112b6fe1617851d8","tlsh":"955131c515f659251ba7b8494a0f9402a327e0033505de55bfcc8740af9936c9bf0bf6"},{"path":"package.json","sha256":"bcee38358ad5bd294ad50ee7e2560e31af11f918580a7b76d3e847f08cdb8e16","tlsh":"81d02e340e21593325c11652086ea84aa6a08f2f01043809a3cb183ca2ee27798ff30e"}],"package_integrity":[{"filename":"utils-style-engine-10.2.4.tgz","hashes":{"sha1":"02d715e536054532222054ea6cfc8324cefbabc1","sha512_sri":"sha512-mxRqMTpWfsKD2Yh9+d2n2lO3GO2zSVc7f5Xa8xjSIIaV8QX31Sksk3ZnEeJ9R6UJV01bWzs9zdgJhRpQ4yDOgA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/utils-style-engine/v/10.2.4"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-010544","import_time":"2026-07-14T18:28:28.0862637Z","modified_time":"2026-07-14T17:56:34Z","sha256":"3049309c5f74bd1b453bcd51803cb7b8ddbbab2d3038f10d13e11a592dff6f52","source":"amazon-inspector","versions":["10.2.4"]}]}}
