Earlier this month, Electrum detected a DoS attack on its network, allegedly launched by a malicious botnet with more than 140,000 machines, designed to provide Electrum to users.

However, after electrum officials said in early 19th that some security mechanisms should be put in place to prevent this "update phishing", many users of Electrum are still in the old version.
The attacker set up a large number of malicious servers. Once a user's Electrum wallet is connected to these servers, they see what appears to be an official message when they send a Bitcoin transaction, telling them to upgrade the Electrum wallet, which actually contains a fraudulent URL.
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.
The Healthy Security Lab is concerned that Nearly 250 bitcoins have been stolen in a recent hacking attack on an Electrum wallet. This attack, confirmed by Electrum, involves creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that it was an ongoing phishing attack on Electrum users and advised them to download wallets from the official website.
Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Devi 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. 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.
"The next difficulty adjustment will change the network so that it deploys arithmetic (hash rate) over the next 2 weeks or so, after which it will be clear whether users will have to pay higher transaction fees after halving," they said. Although bitcoin's median online transaction fee has fallen by more than 50% since mid-May, it is still about five times higher than in April.

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.
