All About Lightning 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.

Summary: According to a Reddit post on March 26, youTube, the video-sharing platform, allegedly miscast malicious ads about Electrum, a Bitcoin (BTC) wallet. In a Reddit post, a user named mrsxeplatypus alerts the public about malware and describes how scam ads work: malicious ads masquerade as an Electrum ad, even showing positive links.
This "update prompt" is not an official act of Electrum, but a phishing attack by an attacker that exploits a message flaw on the Electrum client and the ElectrumX server, which requires the attacker to deploy the malicious ElectrumX server in advance, and the malicious server is localized by the user's Electrum client (because the Electrum client is a light wallet and the user needs the ElectrumX server to broadcast the transaction). At the time of the madness, malicious ElectrumX servers accounted for as much as 71% of the total, and the show did not fully count that hundreds of bitcoins had been stolen in this phishing attack over the past year or so.
Electrum is a well-known light wallet for Bitcoin that adds new features such as server authentication using SSL to prevent MITM attacks. So unlike other Bitcoin light wallets, Electrum cannot communicate directly with different versions of Bitcoin full nodes, and each startup connects to electrumserver to communicate, and electrum.
The Electrum team has announced the attack in an official tweet, saying that "this is an ongoing phishing attack on Electrum users" and reminding them to check the authenticity of the client's source before logging in. The team published its official website, and the Electrum clients downloaded elsewhere may be problematic.
The problem was not fixed. So he had to contact Electrum to highlight the urgency of the issue, and Electrum released Emergency Response Version 3.0.4 a few hours later.
