What is the correct way for exchanges to get users? The author briefly summarizes a few points, in fact, may be more than.
Electrum is a world-renowned Bitcoin light wallet with a long history of multi-signature support 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 "message defects" that allow an attacker to send an "update prompt" through 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. 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, and if you pair it with Electrum, although the private key does not have any security issues, you should also be alert to the replacement of the destination address.

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.
