Background
The oleh-modal package is an npm library designed to provide a wallet-connect modal component for applications. It aims to facilitate user interactions with cryptocurrency wallets like MetaMask, Phantom, Rabby, and OKX. However, the package has been identified as a credential-harvesting phishing kit that deceives users into entering sensitive information.
Vulnerability Detail
The vulnerability originates from the malicious code embedded within the oleh-modal package version 1.0.0.

The captured credentials are sent to a hardcoded backend API at https://api.wagmiwallet.org/api/keys, along with additional user information such as wallet type and geolocation data. This poses a significant risk as any application using this package will inadvertently expose its users' sensitive information to attackers.
