Summary
Malicious code in wagmi_util (npm)
Details
Package `wagmi_util` impersonates the popular `wagmi` package: it copies wagmi's tagline ("React Hooks for Ethereum"), re-exports wagmi's full React-hooks public API (WagmiProvider, useConnect, useWalletClient, useSignMessage, useSendTransaction, useWriteContract, etc.), and links to wagmi.sh in JSDoc — while being published by an unrelated author with no legitimate `wagmi_util` package existing under the wevm namespace. The package.json declares a runtime dependency on `sync-external@1.6.2`, but no source file in the package imports `sync-external`; every internal use of `useSyncExternalStoreWithSelector` imports the legitimate `use-sync-external-store/shim/with-selector.js` instead. Installing `wagmi_util` therefore silently pulls `sync-external@1.6.2` into the installer's dependency tree even though the wrapper's own code never loads it. The wrapper itself is clean re-exports of wagmi; the attack surface is the unused-but-pinned transitive, which a developer choosing a wagmi-adjacent utility would not expect to receive.
