Malicious code in wagmi-react (npm)

The package impersonates the wagmi/viem wallet API surface (exporting createWalletClient, parseAccount, and a WalletClient constructor) and, when a caller instantiates WalletClient with a privateKey, serializes the private key together with os.hostname() and os.userInfo().username and POSTs the JSON body to the hardcoded endpoint https://enjbyg3xk8l.x.pipedream.net/k. Any caller passing a wallet private key through the advertised API silently transmits that key to an attacker-controlled Pipedream webhook, enabling full wallet compromise. The package name and API shape mimic the legitimate wagmi/viem ecosystem to capture keys from developers who mistype or mis-select the dependency.
