The JSON payload is hex-encoded, split into 60-character chunks, and leaked as DNS labels via dns.lookup queries under the hardcoded subdomain da5u87oh92rc72pp1dngqfc6hp8gwshm6.o.jgl.red, with a fallback DNS query on error. The chunked hex-over-DNS transport is a covert-channel technique that evades many egress filters. Package metadata is minimal (placeholder main, empty author) and inconsistent with any legitimate logging library, matching a dependency-confusion reconnaissance beacon pattern.\n","affected":[{"package":{"ecosystem":"npm","name":"manticore-log"},"versions":["9.4.3"],"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":"preinstall.js","sha256":"341c923b92079050e9d2e34a623943638dacc750403c574d9cbf573e99a867ff","tlsh":"7441ac9fdceb0074b826223a9bbf441532e7d3333511ded1b45ce6805fe246826d69e9"}],"package_integrity":[{"filename":"manticore-log-9.4.3.tgz","hashes":{"sha1":"a75b3a1402f0e650a674aa1d13c3d6e6b790811c","sha512_sri":"sha512-ULewEXRA8py7Z+tMpcpbsz0T1J6HdjefPrYw2MqjMtxyl7mCA0ktorG452cgIahQDSIYAf4OgZw+Og9RL5FTQw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/manticore-log/v/9.4.3"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018634","import_time":"2026-08-24T16:49:13.861591709Z","modified_time":"2026-08-24T16:39:49Z","sha256":"184c02a26613b94b15f0abe1ed108c7a2a7a061f795213dba4772876e6e0a015","source":"amazon-inspector","versions":["9.4.3"]}]}}
