According to the slow fog zone, the Phishing attack by Electrum forged upgrade tips has stolen at least 200 BTCs, and this attack cannot be avoided by upgrading Electrum alone, requiring the entire ecological service to make corresponding changes (because Electrum is not a full node, and then on the transaction broadcast and the corresponding server has a message communication, the attacker can also deploy a malicious server)
In recent days, hackers or hacker groups have stolen more than 200 bitcoins worth about $750,000 by attacking the infrastructure of electrum Bitcoin wallets. The attacker is targeting Electrum.
Electrum used to be a development team that was responsible for driving early Sandworm activities, but in the CrashOverride event, it also held development and operational roles. According to the data, electrum caused a major power outage in Ukraine in 2016 with the ICS malware CrashOverride, however, because Electrum is also described as an organization that "can develop malware and ICS protocols that can modify the processes of electrical devices", the organization does not rely on exploiting vulnerabilities or zero-day vulnerabilities, but exploits common exploits and methods to launch attacks. For example, the organization used Microsoft's database server as a gateway to commercial and industrial control networks, successfully breaking industrial control systems and using stolen credentials to execute code. As a result, Dragos believes that Electrum is one of the most capable and complex threat groups in the ICS industry today, and in its report, it highlights that "North American power companies should view Electrum as a serious threat."

Electrum Bitcoin Wallet is a reliable service that has been around since 2011. It is called a "thin" cold wallet, where the entire blockchain is not downloaded to the user's device but stored on a network server. In this case, the private key is stored encrypted on the user's computer and is never sent to the server.
Examples of online wallets: Breadwallet (BRD), Mycelium, Electrum, Out of Egypt.
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.
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.
Bitcoin wallet Electrum now supports Lightning online payments, according to Coindesk on July 11. 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.
