Attackers reportedly created their own Electrum servers, which hosted the attacked version of Electrum in order to implement the attack. When the user will be vulnerable.
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.
A new repo qtum-electrum-new was built to add qtum-related features to the latest code for Bitcoin electrum.
Electrum is a mobile available Bitcoin wallet that can also be used for Windows, Mac, Linux.
Like Bitcoin's core wallet, Electrum Wallet allows users to control their own funds and private keys. Electrum wallets' private keys can also be exported and used on other supported wallets to access funds. Electrum apps are available for Windows, Linux, OSX and Android, but do not support iOS and browser clients.

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.
When an Electrum wallet queries a third-party Electrum server, the server can link two transactions together and know which address is a zero address.

Macintosh users make up 7.28 percent of all network users, according to Research Group Net Market Share. There are other wallets available for OSX systems, mainly MultiBit and Electrum and, of course, Bitcoin QT, but these wallets are not related to the operating system and can be used for Linux, Windows and Mac.
The main reason for the Trezor vulnerability is that it does not have built-in multi-signature functionality, so its multi-signature implementation is to support Electrum extensions. This leads to an attack on Electrum, and Trezor is affected.
The attacker set up a large number of malicious servers. Once a user's Electrum wallet is connected to these servers, they see what appears to be an official message when they send a Bitcoin transaction, telling them to upgrade the Electrum wallet, which actually contains a fraudulent URL.
According to The Next Web, the attackers even implemented their own Electrum servers, which hosted the attacked Electrum.
