All About Lightning Electrum
The Healthy Security Lab is concerned that Nearly 250 bitcoins have been stolen in a recent hacking attack on an Electrum wallet. This attack, confirmed by Electrum, involves creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that it was an ongoing phishing attack on Electrum users and advised them to download wallets from the official website.

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.
Electrum is another popular Bitcoin wallet that has been around for nearly a decade. Electrum Bitcoin Wallet has been available for all devices since 2011 and was one of the most widely used wallet applications before other alternatives emerged. There are still a lot of people who are still swearing at the Electrum wallet.
First, Electrum implemented its own Lightningwatch watchtower, an important part of the Lightning Network, which scans the Bitcoin blockchain to detect and prevent fraud.
According to GitHub, Bitcoin Desktop Wallet client Electrum has released a 4.0 beta version, adding several important updates that support lightning networks. Electrum primarily adds features such as PSBT (partially signed Bitcoin transactions), Lightning Network, watchtowers (暸 watchtowers), and Submarine Swaps (subliminal switching).
As of press time, phishing attacks that forged Electrum upgrade notifications have stolen at least 1,450 BTC (the number stolen is officially counted by a user, anti-malware companies Malwarebytes and Electrum), with a total value of approximately $11.6 million. It is worth mentioning that Electrum versions lower than 3.3.4 are vulnerable to such phishing attacks. Users who use Electrum wallets should update to the latest version Electrum 3.3.8 through the official website (electrum.org). At present, v4.0.0 has not been officially released.
