@wrenfield/viem @2.53.4

Summary

Package @wrenfield/viem impersonates the popular viem library (homepage viem.sh, repo wevm/viem); README and authors fields credit the real viem maintainers but the package itself is published under an unrelated @wrenfield scope. The shipped source under _cjs/ mirrors viem's real code, but package.json rewrites the abitype dependency via npm alias: "abitype": "npm:@wrenfield/abitype@1.2.4" . The CommonJS entry _cjs/index.js calls require("abitype") at module load, so any installer who require() s or import s @wrenfield/viem transitively pulls and executes code from @wrenfield/abitype@1.2.4 — a separate package under the same attacker-controlled scope, outside this tarball. The combination of brand impersonation of a top npm package plus a silent dependency redirect to an attacker-controlled namespace is the namespace-abuse / dependency-hijack pattern: the lure package looks legitimate on inspection, while the actual payload is delivered through the redirected dependency at first import.
