At this time, the SPV-based Electrum wallet became the new favorite of Bitcoin players. Especially for small partners who are new to Bitcoin, editors recommend using electrum wallets.

Another upgrade under study is the release of a new version of the Electrum-LTC desktop wallet. Electrum-LTC is an SPV wallet that can be used in Windows, Linux, and OS X operating systems.

Users of cryptocurrencies Wallet Electrum and MyEtherWallet are facing phishing attacks, according to posts posted on Reddit and Twitter on February 4. The MyEtherWallet team has issued a warning about phishing emails sent to users. Electrum also posted a warning on its website informing users that the electrum version, which predies 3.3.3, is vulnerable to phishing attacks. The company warned its users not to download software updates from other sources. (Cointelegraph)

The main reason for the Trezor vulnerability is that it does not have built-in multi-signature functionality, so its multi-signature implementation is to support Electrum extension. This led to an attack on electrum, and Trezor was affected.

As mentioned earlier, because electrum light wallets are different from Bitcoin light wallets such as MultiBit or Breadwallet, they cannot communicate directly with bitcoin full nodes and can only communicate with electrum.

In December 2018, Slow Fog first discovered and alerted an attacker to a messaging flaw using the Electrum Wallet client to force an "update prompt" to pop up when a user transfers money, inducing users to update and download malware to carry out a currency theft attack. Although electrum officials said in early 2019 that some security mechanisms were in place to prevent this "update phishing", many users of Electrum are still in the old version (less than 3.3.4) and the old version is still under threat. However, we do not rule out a similar threat to the new version.

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.
