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.

The Healthy Security Lab is concerned that Nearly 250 bitcoins have been stolen in a recent hacking attack on an Electrum wallet. This attack, confirmed by Electrum, involves creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that it was an ongoing phishing attack on Electrum users and advised them to download wallets from the official website.
Wallet developer Electrum has released an emergency patch for a key vulnerability in bitcoin wallets. The vulnerability makes it possible for any website hosting an e-wallet to steal a user's cryptocurrency. The vulnerability means that in the JSONRPC interface, the password is exposed, implying that the hacker has full control of the wallet. However, the first patch failed to resolve the issue, forcing Electrum to release a second update on Sunday night.
It's not hard to run your own Electrum server and point your wallet to just use it. This restores Electrum to the point where it has the same privacy and security attributes as the full node, where no one else can see the address or transaction that the wallet is interested in. Electrum then becomes an all-node wallet.
This isn't the first time Thatectrum has appeared in a fake version, with hackers developing a fake encrypted wallet, Electrum, in December, resulting in the theft of nearly 250 bitcoins worth about $1 million. In January, GitHub discovered a fake Electrum wallet called "Electrvm" designed to steal users' money. In February, users of encrypted wallets Electrum and MyEtherWallet reported that they were facing phishing attacks. (Stationer's House)
So far, Electrum Wallet has gone through various iterations to keep up with the growth of the cryptocurrencies industry to provide its users with a high level of security at any time. The wallet is easier to use than Bitcoin Core wallets and allows users to create wallets with other security features, such as two-factor authentication, multi-signature wallets, and more. In addition to creating and using new wallets, Electrum allows users to import other Bitcoin blockchain wallets by entering the wallet's seed or master key. It can also be used to manage hardware wallets.
The Electrum client is a classic light wallet that relies on Bitcoin data from remote servers. Its focus is fast, simple and takes up less resources. It uses a remote server to handle the most complex parts of the Bitcoin system, and you can restore your wallet with a preset secret phrase. RPCAPI is available for business access.
