The beacon fires unconditionally on every install, with no user opt-in, no configuration, and no disclosure in the package's advertised purpose. The destination is an author-controlled subdomain unrelated to any npm registry or vendor infrastructure.\n","modified":"2026-08-19T07:00:38.075878363Z","published":"2026-08-19T06:47:49Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-08-19T06:47:49Z","sha256":"379b8e968c18bc5df2f2e00ad56f6c1c139bc97d4a8b19e6d1a917398ad72e58","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-018384","import_time":"2026-08-19T06:49:44.568103223Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/karma-proxy/v/1.0.0"}],"affected":[{"package":{"name":"karma-proxy","ecosystem":"npm","purl":"pkg:npm/karma-proxy"},"versions":["1.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/karma-proxy/MAL-2026-14267.json","cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"package_integrity":[{"filename":"karma-proxy-1.0.0.tgz","hashes":{"sha1":"d2f16beedc54c1d9c58a41c00eca2ede796bd3ab","sha512_sri":"sha512-VE8Oj6lv7i2P/TpiIEiW4eb0uQWmUZCw8mS6bUvakbW+A+zjQBcqeXiGsRpMa7gJFQgOWjpLOeYSa5ee8MNeEw=="}}],"evidence_files":[{"sha256":"a11b4d199798c77b9ec2ae949b4feef21c4aa7c68be4d85b981a4627422672c7","tlsh":"6f0123c5d2b55a3557b852c028f16f0793fbf2233b0224b679c444e92f8d0f9003219c","path":"postinstall.js"}]}}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
