Users of Bitcoin wallet Electrum are currently facing a phishing attack, according to the Devi Security Lab. Hackers broadcast messages to electrum clients through a malicious server, prompting the user to update to v4.0.0, and if the user follows the prompt to install the backdoor-carrying client, the private key is stolen and all digital assets are stolen. At the time of writing, at least 1,450 BTCs worth approximately $11.6 million had been stolen from phishing attacks that forged Electrum upgrade alerts. Devi Security Labs hereby suggests that versions of Electrum below 3.3.4 are vulnerable to such phishing attacks, and users using Electrum Wallet are requested to update to the latest version of Electrum3.3.8 via the official website (electrum.org), which has not yet been officially released v4.0.0, and do not use the link in the prompt message to avoid asset losses.

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 "message defects" that allow an attacker to send an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing to 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.

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.
