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
Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Devi 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 worth about $11.6 million had been stolen from phishing attacks that faked Electrum upgrade tips. DeViable Security Labs hereby suggests that versions of Electrum below 3.3.4 are vulnerable to such phishing attacks, and users using Electrum Wallet 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, and do not use the link in the prompt to avoid asset losses.
Of course, there are wallets that are not designed according to BIP rules, such as Electrum, which was the first wallet to use mnic patterns, and the first determinative wallet, which was introduced in 2011, and later The micound rule BIP-39, which became a recognized industry standard with its widespread use. Electrum is similar to BIP-39's monemone rules, but BIP-39 uses a fixed set of 2048 thesavers, and Electrum uses a different thesaver, but is compatible with BIP-39's monemone thesaver, and the reverse is not compatible.
If you haven't set up Electrum Wallet to be compatible with your phone wallet, you can use the private key to recover the Electrum wallet on your web wallet. Select Wallet - "Private Key" - "Export" on the Electrum wallet and you will export the file qtum-electrum-private-keys.csv or copy only one private key. Select Recover from WIF on your web wallet, paste the private key, and select Confirm. Check that the wallet address is correct. You may need to use Dump as a Key File to save the key file.

We expect the EVM to return an error if the input validation fails. You can read more about error handling in Solidity here.
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.
