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. Devi Security Labs is here to remind users not to install unknown sources of Electrum wallets, to avoid asset losses.

A new version of Electrum Wallet v0.18.16 was released.
A new repo qtum-electrum-new has been built to add qtum-related features to the latest code for Bitcoin electrum.
DeViable 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 Electrum 3.3.8 via the official website (electrum.org), which has not yet been officially released, and do not use the link in the prompt to avoid asset losses.
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.
