In early April, Cointelegraph reported that the ongoing DoS attack on the Electrum network was allegedly launched by a malicious botnet of more than 140,000 machines in order to steal a user's BTC by calling it a fake version of electrum software.

Individual users can activate Blockstream Esplora's lightweight mode, significantly reducing disk space requirements, but at the expense of reduced scalability and DoS resistance. Lightweight mode still provides blockchain browser and Electrum server functionality, and performance is sufficient for a home or small office.

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). At the time of the madness, malicious ElectrumX servers accounted for as many as 71% of the total, and the show doesn't fully count that hundreds of bitcoins have been stolen in this phishing attack over the past year or so.

Index servers are mostly difficult to install and run in production environments, such as Insight servers that need to reset APIs for certain types of data, followed by WebSockets and socket.io. In addition, the Stratum API used by the Electrum server is too cumbersome and cumbersome.

In an April 29 blog post, Malwarebytes, an antimalware software company, said the number of infected Electrum Bitcoin wallets had reached 152,000 after the server was attacked by DoS. Malwarebytes found that the number of infected machines in botnets had reached 152,000, and the total amount of stolen funds had risen to $4.6 million. The company identified a loader called Trojan.BeamWinHTTP, which also involved downloading previously detected Electrum DoSMiner. The largest botnets are reported to be concentrated in asia-Pacific, Brazil and Peru, and botnets attacking Electrum infrastructure are growing. (Cointelegraph)

Why use Electrum? Here are a dozen of the benefits of electrum wallets.

Until now, the ElectrumX original was the only server available for the P2P exploration protocol, resulting in almost all Electrum wallets relying on servers running on the original ElectrumX. This week, we introduced P2P exploration as an optional feature of Esplora. In this case, Esplora is the only other option for electrum servers designed for public wallets.

According to slow fog zone news, Electrum fake upgrade tips of the phishing attack has stolen at least 200 BTC, this attack by upgrading Electrum alone can not be avoided, the need for the entire ecological service to make corresponding changes (because Electrum this client is not a full node, and then on the transaction broadcast and the corresponding service side of the message communication, attackers can also deploy malicious server). Slow fog zones remind users that phishing attacks like Electrum require long-term vigilance. The slow fog zone has previously issued an alert for selectrum phishing updates, and hackers who attacked Electrum wallets used Electrum's software to unusually construct malicious software update prompts to induce users to update and download malware usage.

To synchronize information on the Bitcoin blockchain, Phoenix Wallet connects to a random Electrum server. However, to provide greater confidence, it allows you to modify this connection, making it easier for you to connect to a trusted server or your own server.

Users of Bitcoin wallet Electrum are currently facing phishing attacks, according to Johnwick.io, a 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.

This technology has been in the industry for a long time. Connecting hardware to an all-node is also one of the key goals of the Electrum Personal Server project pioneered by developer Chris Belcher. He said in a project announcement last year.

According to security firm Slow Fog, the current latest version of Bitcoin Light Wallet Electrum is 3.3.8, while previous versions of 3.3.4 are known to have "message defects" that allow attackers to send "update prompts" over a malicious ElectrumX server. This "update tip" is very confusing to the user, and if you follow the prompt to download the so-called new version of Electrum, you may be tricked. User feedback because of this attack, stolen bitcoins in more than four digits.

The cyberattack on Electrum wallets allowed hackers to steal nearly $1 million worth of BTC.

For example, in the article "The Simplest Way to Make BTC Cold Wallets", three methods of making cold wallets using different wallets (bitcoin core, Bieber wallet, electrum) are introduced.

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

It turns out that the FTP account password used to upload local user information, with a normal Electrum Installer file, is used once the user installs it, and sensitive information entered under Electrum is sent to a remote malicious FTP server for reception.

Bitcoin Wallet Electrum now supports Lightning Online Payments According to Coindesk July 11th, Bitcoin Wallet Electrum now supports Lightning Web Payments. It has previously been reported that Bitcoin Wallet Electrum has released a beta version of Electrum 4.0, adding support for the Bitcoin Lightning Network.
