    Bitcoin is an Internet-based digital currency that, like the U.S. dollar, can circulate globally. Bitcoin, however, has no physical objects, cannot be carried in a pocket, and cannot be put in a wallet. Only those who want to transfer bitcoins online (on the blockchain) need a "Bitcoin wallet program" on their mobile phone or computer, as well as a Bitcoin receiving address (account number) of the payer (the recipient). Enter the other person's Bitcoin address in the Bitcoin Wallet app, enter the transfer amount, then click Send, enter your password, and in a few minutes, Bitcoin will be transferred from your wallet address to the other person's wallet address.

    The private key is a secret block of data that proves your right to consume Bitcoin from a particular wallet, implemented through a cryptographic signature. If you're using wallet software, your private key is stored on your computer, and if you're using an online wallet, your private key is stored on a remote server. Never disclose private keys because they allow you to consume bitcoins in your Bitcoin wallet.

    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)

    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-signature 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.
