There's a big problem with non-determinic wallets: every new private key is backed up again, more and more private keys need to be backed up, and import can be cumbersome.

When Electrum wallets are synchronized with malicious servers, they are instructed to "update" clients provided by hackers, resulting in the loss of assets contained in older versions. Previously, in December 2018, Electrum.
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 "this is an ongoing phishing attack on Electrum users and advised users to download wallet apps from the official website" and that The Healthy Security Lab advised users not to install an unknown source of Electrum wallets to avoid being tricked.
According to slow fog zone news, Electrum fake upgrade tips of the phishing attack has stolen at least 200 BTC, this attack by upgrading Electrum alone can not be avoided, the need for the entire ecological service to make corresponding changes (because Electrum this client is not a full node, and then on the transaction broadcast and the corresponding service side of the message communication, attackers can also deploy malicious server). Slow fog zones remind users that phishing attacks like Electrum require long-term vigilance. The slow fog zone has previously issued an alert for selectrum phishing updates, and hackers who attacked Electrum wallets used Electrum's software to unusually construct malicious software update prompts to induce users to update and download malware usage.
One of the most anticipated changes to Cryptocurrencies Core 0.18.0 will be the ability to connect users to their hardware wallets (Ledger, Trezor, Digital BitBox, KeepKey, and Coldcard) via the Hardware Wallet Interaction (HWI) tool. This combines one of the most secure ways to store private keys and interact with cryptocurrencies. Hardware wallets are considered secure because the user's private key never leaves the device. Keys are never exposed to the Internet or the computers they are connected to, protecting the hardware wallet from remote hackers. Although you can already use the Electrum personal server to connect the hardware wallet to the Electrum wallet connected to the entire node, HWI will be the first local, hardware-to-node choice for the Bitcoin Core project. Currently, HWI scripts are still only on the command line and require manual procedures to connect hardware wallets.
The fact that not many people know is that Esplora is bundled with a based and optimized Electrum server. This Electrum server is derived from Electrs and is now maintained separately by the Blockstream engineering team. Over the past two years, Esplora has become one of the fastest and most scalable Electrum server solutions available for Bitcoin due to continuous updates and performance optimization. Esplora is also the only Electrum server that supports liquid networks.
Electrum tweeted today about the incident, saying it was "a persistent phishing attack on Electrum users" and imploring users to check the effectiveness of the resources they log on to.
Key private key A private key in the context of bitcoin is a number number allows the bitcoins to be spent. Every Bitcoin wallet contains one or more private keys, the are saved in the wallet file. The private keys are are related to all Bitcoin called for the wallet. -Wiki.

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.
Electrum is a well-known light wallet for Bitcoin that adds new features such as server authentication using SSL to prevent MITM attacks. So unlike other Bitcoin light wallets, Electrum cannot communicate directly with different versions of Bitcoin full nodes, and each startup connects to electrumserver to communicate, and electrum.
Star Daily News Bitcoin Wallet Electrum official Twitter announced that the next version of Electrum will support Lightning online payments. Its lightning node implementation has been consolidated into the main branch of Electrum. Electrum also confirmed that the wallet will adopt a new implementation of in-house development written using Python. (Cointelegraph)
