BitPay said in a user recommendation that Copay is not irresceable from malicious code attacks, but BitPay's team is investigating whether any CoPay users were exploited by the vulnerability. It is recommended that users of CoPay from versions 5.0.2 to 5.1.0 do not run and open the app.
Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum Wallet is fast and has few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.
By default, electrum wallets are randomly connected to a set of Electrum servers. From a privacy perspective, this is not a good thing because it discloses your wallet address and balance to unknown third parties. And unfortunately, many public Electrum servers are run by individuals or groups of blockchain analytics companies or worse. Therefore, if you are using an Electrum wallet, it is generally recommended that you run your own Electrum server and then connect the wallet to that server.
