Individual users can activate Blockstream Esplora's lightweight mode, significantly reducing disk space requirements, but at the expense of reduced scalability and DoS resistance. Lightweight mode still provides blockchain browser and Electrum server functionality, and performance is sufficient for a home or small office.
According to Johnwick.io, we will continue to monitor and track the further flow of funds after a recent user submitted a coin-losing incident claiming that the download used an Electrum wallet had been phishing and that more than 700 bitcoins had been lost, and that the stolen address had been added to the Devi AML system. It is reported that malicious websites (electrumsecure) fake Electrum website phishing attacks, to guide users to download and use the wallet, in order to steal the user's private key and other sensitive data.

A new repo qtum-electrum-new has been built to add qtum-related features to the latest code for Bitcoin electrum.
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 wallets are fast and have 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.
Implement blacklisting logic to alert malicious servers outside the Electrum client view.

Hackers launched a denial-of-service (DoS) attack on a well-known wallet Electrum server, according to Johnwick.io. Hackers used botnets of more than 140,000 computers to attack Electrum nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials. De-dimensional Security Labs recommends that users of electrum wallets be updated to the latest version of the client through the official website and never use the link in the prompt message.
Electrum is a world-renowned Bitcoin light wallet with a long history of multi-signature support and a very broad user base, many of which like to use Electrum as a cold wallet or multi-signature wallet for Bitcoin or even USDT (Omni). Based on this usage scenario, Electrum is used less frequently on the user's computer. The current version of Electrum is 3.3.8, and previous versions of 3.3.4 are known to have a message flaw that allows an attacker to send update prompts through a malicious ElectrumX server. This update prompt is very confusing for the user, and if you follow the prompt to download the so-called new version of Electrum, you may be tricked. According to user feedback, because of this attack, stolen bitcoins are in the four digits or more. This captured currency theft attack is not stealing the private key (electrum's private key is generally stored with two-factor encryption), but replaces the transfer destination address when the user initiates the transfer. In this slow fog remind users, transfer, need to pay special attention to whether the destination address is replaced, which is a very popular recent way to steal money. It is also recommended that users use hardware wallets such as Ledger, and if you pair it with Electrum, although the private key does not have any security issues, you should also be alert to the replacement of the destination address.
The Electrum team has also been developing other features. Electrum Wallet users can view the full release notes here.
Electrum hackers pre-empted a large number of "normal" electrum servers on the P2P network.
