Electrum is a world-renowned Bitcoin light wallet with a long history of supporting multi-signatures and a very broad user base, many of which like to use Electrum as a cold wallet or multi-sign 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 an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing for the user, and if you follow the prompt to download the so-called new version of Electrum, you may get a trick. 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. Here we remind users that when transferring money, special attention needs to be paid to whether the destination address has been replaced, which is a very popular method of currency theft recently. It is also recommended that users use hardware wallets such as Ledger, if paired with Electrum, although the private key will not have any security issues, but also need to be alert to the target address is replaced.

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.
In a recent announcement on Twitter, Electrum advised users to disable the automatic connection option and manually select a server, while the company is developing a more powerful Electrum.
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.
