All About Lightning Electrum
Electrum Wallet is one of the most popular Bitcoin wallets and has been around for several years. However, Electrum wallet users often rely on Electrum servers, which presents some security and privacy trade-offs. If you use electrum personal servers, Electrum wallet users can connect locally to their own private servers, enjoying the convenience of Electrum without any trade-offs.
Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Devi Security Lab. 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.
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.

Lightweight Bitcoin Wallet Electrum announced that the next version will support Lightning network payments, implemented with Python, an electrum network node where wallet users do not need to run Lightning network nodes themselves to make payments, and electrum's Lightning network nodes have now been merged into the Electrum master branch.
Reddit user u/normal_rc: 'The attacker set up a lot of malicious servers. Once a user's Electrum wallet is connected to these servers, they see what appears to be an official message when sending bitcoin transactions, telling them to upgrade the Electrum wallet, which actually contains a fraudulent URL.
