Lightning support in Electrum has been around for a long time. Thomas Voegtlin, the founder of Electrum, first told CoinDesk last summer that Lightning would take it to the next version.
A new version of Electrum Wallet v0.18.16 was released.
In recent days, hackers or hacker groups have stolen more than 200 bitcoins worth about $750,000 by attacking the infrastructure of electrum Bitcoin wallets. The attacker is targeting Electrum.
Electrum - Lightweight Bitcoin client.
In short, if you are looking for a Bitcoin wallet, then you must try Electrum.
Lesson 1: Third-party Electrum servers can link your two transactions together. This can be avoided by running your own Electrum server, supported by your own full node.
B: Electrum server can customize messages to appear in the user's electrum light wallet software, giving hackers a chance to broadcast phishing messages.
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.
The Electrum development team also warned them that they had nothing to do with a project called Electrum Dark: they used our name without our permission. Be careful with the altcoin version of Electrum, as they are sometimes used as vectors to install malware against your real Bitcoin wallet.
Users of Bitcoin wallet Electrum are facing phishing attacks, according to Johnwick.io. Hackers broadcast messages to the Electrum client through a malicious server, prompting the user to update to v4.0.0, and if the user follows the prompt to install this "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 about $11.6 million had been stolen from phishing attacks that faked Electrum upgrade tips. 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.
