@marketfront/digitalherobannercarousel @7.0.0

Summary

@marketfront/digitalherobannercarousel@7.0.0 is a dependency-confusion lure published to public npm under a scope the target organization does not own. The tarball has no real library implementation (dist/index.js re-exports a src/index.js that is not shipped), and package.json declares 'postinstall': 'node scripts/postinstall.js'. scripts/postinstall.js is a ~160 KB obfuscator.io-style bundle (rotated string array, RC4-decoded literals, control-flow flattening) that decodes strings — module names, env-var names, sensitive file paths, and the C2 host — only at runtime. On npm install, the decoded payload builds a host fingerprint (hostname, username, home/tmp dirs, platform, arch, release, uptime, cpus, memory, network interfaces, plus Windows USERDOMAIN/COMPUTERNAME/APPDATA/LOCALAPPDATA/PROGRAMDATA/TEMP), captures the entire process.env and npm user-agent, and reads/INI-parses local credential/config files via a runtime-derived candidate path list. Collected data is XOR-encrypted and exfiltrated over two channels: base32-encoded chunks issued as dns.resolve() lookups against subdomains of the runtime-decoded C2 host (DNS smuggling for egress-filter evasion), plus HTTPS/HTTP POST of the same encrypted body with retry/backoff. The payload also inspects process.execArgv and NODE_OPTIONS for --inspect/--debug tokens and runs a timing check to skip execution under a debugger or instrumented sandbox.
