    Summary: Malicious code in manticore-log (npm)

    Details: Source: amazon-inspector (184c02a26613b94b15f0abe1ed108c7a2a7a061f795213dba4772876e6e0a015) The package's preinstall lifecycle script fires automatically on npm install and collects the installer's OS username, hostname, current working directory, and the enclosing project's package.json name/author/version (obtained by walking up parents of __dirname). 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.
