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.

The fact that not many people know is that Esplora is bundled with a based and optimized Electrum server. This Electrum server is derived from Electrs and is now maintained separately by the Blockstream engineering team. Over the past two years, Esplora has become one of the fastest and most scalable Electrum server solutions available for Bitcoin due to continuous updates and performance optimization. Esplora is also the only Electrum server that supports liquid networks.
According to the dimensionality reduction security laboratory (johnwick.io), hackers launched a denial of service (DoS) attack on the well-known wallet Electrum server. The hackers used a botnet of more than 140,000 computers to attack Electrum nodes and deployed malicious nodes at the same time .

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 a message flaw that allows an attacker to send update prompts through a malicious ElectrumX server. This update prompt is very confusing for 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. This captured currency theft attack is not stealing the private key (electrum's private key is generally stored with two-factor encryption), but replaces the transfer destination address when the user initiates the transfer. In this slow fog remind users, transfer, need to pay special attention to whether the destination address is replaced, which is a very popular recent way to steal money. It is also recommended that users use hardware wallets such as Ledger, and if you pair it with Electrum, although the private key does not have any security issues, you should also be alert to the replacement of the destination address.

According to Bleeping Computer, the BTC wallet app Electrom accused a phishing product called Electrum Pro of stealing a user's seed key on May 9 on GitHub 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 BTC URLs managed by Eletrum Pro.
Electrum wallets have been hacked in recent days and nearly 250 bitcoins have been stolen, according to blockchain security team Devi Security Labs.

This isn't the first time Thatectrum has appeared in a fake version, with hackers developing a fake encrypted wallet, Electrum, in December, resulting in the theft of nearly 250 bitcoins worth about $1 million. In January, GitHub discovered a fake Electrum wallet called "Electrvm" designed to steal users' money. In February, users of encrypted wallets Electrum and MyEtherWallet reported that they were facing phishing attacks. (Stationer's House)
In response to an earlier April 9 news that Bitcoin Wallet Electrum had been attacked by the botnet DoS, Devi Security Lab analysis said hackers used botnets of more than 140,000 computers to attack Electrom's nodes and simultaneously deploy malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials.
