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.

Electrum hackers pre-empted a large number of "normal" electrum servers on the P2P network.
By default, electrum wallets are randomly connected to a set of Electrum servers. From a privacy perspective, this is not a good thing because it discloses your wallet address and balance to unknown third parties. And unfortunately, many public Electrum servers are run by individuals or groups of blockchain analytics companies or worse. Therefore, if you are using an Electrum wallet, it is generally recommended that you run your own Electrum server and then connect the wallet to that server.
According to Bleeping Computer, the Bitcoin wallet app Electrom was on GitHub on May 9th, accusing a phishing product called Electrum Pro of stealing a user's seed key and registering a domain name called electrum without Electrum's permission. The Electrum team noted that there was a piece of code indicating that the counterfeit product might have taken the user's seed key and uploaded it to the electrum. Affected users should transfer funds from Bitcoin URLs managed by Eletrum Pro.
