Qtum Electrum is a Qtum desktop light wallet modified from the well-known Bitcoin wallet Electrum. Compared to the current Qtum Core full-node wallet, Qtum Electrum takes up less disk space and takes less time to synchronize chunks, supports multi-signature and hardware wallets, supports cold wallet mode, supports the import of mnomes into mobile wallets, and uses SPV authentication to ensure security.
The electrum and Electrum-LTC versions below 3.3.3 are vulnerable to phishing attacks in which a malicious server displays a message asking the user to download the fake Electrum. To prevent user exposure, versions older than 3.3 can no longer connect to public servers and must be upgraded. Do not download software updates from sources other than electrum.org and electrum-ltc.org.
Google researcher Tavis Ormandy discovered the Bitcoin wallet Electrum.
Electrum is a world-renowned Bitcoin light wallet with a long history of supporting multi-signatures and a very broad user base, many of which like to use Electrum as a cold wallet or multi-sign 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 an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing for the user, and if you follow the prompt to download the so-called new version of Electrum, you may get a trick. 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. Here we remind users that when transferring money, special attention needs to be paid to whether the destination address has been replaced, which is a very popular method of currency theft recently. It is also recommended that users use hardware wallets such as Ledger, if paired with Electrum, although the private key will not have any security issues, but also need to be alert to the target address is replaced.

Like Bitcoin's core wallet, Electrum Wallet allows users to control their own funds and private keys. Electrum wallets' private keys can also be exported and used on other supported wallets to access funds. Electrum apps are available for Windows, Linux, OSX and Android, but do not support iOS and browser clients.
The wallet, called Electrum, is popular with foreign netizens, but a recent phishing attack on the wallet led to the theft of a user's private key, with BTC being diverted by hackers.
