Why is MetaMask unsafe?

I've heard some concerns about MetaMask's safety, but as a professional practitioner in the field of cryptocurrency and finance, I'm curious to understand the specific reasons behind these concerns. MetaMask is widely regarded as a secure and reliable wallet for storing and managing digital assets on the Ethereum blockchain. It offers a range of security features, including password protection, hardware wallet integration, and mnemonic phrases for wallet recovery. So, could you please elaborate on the safety issues with MetaMask? Are there specific vulnerabilities or attacks that have been identified? Or are these concerns more general and based on misunderstandings or outdated information? I'm interested in understanding the details behind these assertions so that I can provide a more informed response. It's important to note that the safety of any cryptocurrency wallet ultimately depends on the user's behavior and practices. Secure passwords, regular updates, and cautious handling of private keys are all crucial for maintaining the safety of a wallet like MetaMask. Therefore, it's essential to approach these questions with a balanced and informed perspective.
