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.
Public key: The public key is generated based on the private key, but the public key does not allow the private key to be calculated. The role of the public key is to tell other investors, "I am the owner of this private key."

Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Dev Security Lab. Hackers broadcast messages to the Electrum client through a malicious server, prompting the user to update to v4.0.0, and if the user follows the prompt to install this "backdoor-carrying client", the private key is stolen and all digital assets are stolen. At the time of writing, at least 1,450 BTCs (stolen by one user, antimalware firm Malwarebytes and Electrum) had been stolen in phishing attacks that faked Thelectrum upgrade tips, with a total value of about $11.6 million. It is worth mentioning that less than version 3.3.4 of Electrum is vulnerable to such phishing attacks, users using electrum wallets 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 v4.0.0, please do not use the link in the prompt message to update to avoid loss of assets.
When some people hear that blockchain technology integrates public key infrastructure, they immediately believe that it essentially supports authentication. This is not the case because there is no one-to-one match between the private key pair and the user (the user can have multiple private keys), and there is no one-to-one match between the blockchain address and the public key (multiple blockchain addresses can be exported from a single public key)
Top-level private key BOSS self-master, sub-private key dynamic calculation does not touch the net, hardware holding, pure cold operation;
As mentioned above, keystore files encrypt the stored user's private key, but simply encrypting the stored private key is not enough. For example, if a user enters the wrong password, a private key may be recovered, but the private key is no ready the private key that really owns the asset, and the wallet does not know if the recovered private key is correct. This is because the wrong password is in the process of recovering the private key, because the decryption algorithm does not recognize the correctness of the exit order (because the only encryption function is not recognized)
Danny Scott, chief executive of CoinCorner, the UK cryptocurrency exchange, tweeted that some of the addresses that had appeared on court documents filed by CSW had just collectively signed a message using the private key that read, "CSW is a liar and a fraudster."
