Summary

eth-slint is a typosquat of web3-core-subscriptions. src/index.js contains a clean 2119-byte copy of the legitimate web3.js subscriptions module, while lib/index.js (the shipped main entry) contains that same code plus an appended ~149KB obfuscated blob passed to a top-level Function(...) constructor with a custom decoder routine, signed-int mixing table, and hex-escaped byte array. The Function() invocation fires at module load time, executing the decoded payload on the installer's host whenever the package is required or imported. The payload is present only in lib/, not in src/, indicating post-build injection rather than a normal compilation artifact.
