is electrum an offline wallet?

Popular wallet developer Electrum has released an emergency patch for a key vulnerability in Bitcoin wallets.

Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum wallets are fast and have few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.

Bitcoin Wallet Electrum has released a beta version of Electrum 4.0, which supports the Lightning Network.

Slow Fog: Bitcoin Wallet Electrum updates the phishing theft that continues.

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.

Planet Daily News Electrum is a world-renowned Bitcoin light wallet with a long history of supporting multi-signatures and a very broad user base, many of which like to use Electrum as a cold wallet or multi-sign 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 a "message flaw" that allows an attacker to send an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing for the user, and if you follow the prompt to download the so-called new version of Electrum, you may get a trick. According to user feedback, because of this attack, stolen bitcoins are in the four digits or more.

At this time, the SPV-based Electrum wallet became the new favorite of Bitcoin players. Especially for small partners who are new to Bitcoin, editors recommend using electrum wallets.

A clone site masquerading as an Electrum SV wallet has emerged. The cloning site has nothing to do with electrum SV and is designed to steal tokens and create chaos in the BSV community. Most interestingly, although the clone site claims to be a BSV wallet, it is full of links to BCH resources, including the Electron Cash (BCH Wallet) library on GitHub.

This "update tip" 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). In a frenzy, malicious ElectrumX servers account for as many as 71% of the total, and the show doesn't fully count, and hundreds of bitcoins have been stolen in this phishing attack over the past year or so.
