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.
However, after electrum officials said in early 19th that some security mechanisms should be put in place to prevent this "update phishing", many users of Electrum are still in the old version.
Electrum Wallet is one of the most popular Bitcoin wallets and has been around for several years. However, Electrum wallet users often rely on electrum servers, which presents some security and privacy trade-offs. If you use an Electrum personal server, Electrum wallet users can connect locally to their own private servers, enjoying the convenience of Electrum without any trade-offs.
Send two transactions to the network at the same time, one to yourself (pay more for miners) and one to merchants. Because the deals sent to you contain higher miner fees, the probability of being prioritized by miners is high.

how to send higher miner fee electrum
The idea behind MEVA is extremely simple: rather than preventing a run, it's better to auction the right to sort trades and let the winner of the auction (called "Sequencer") sort the trades arbitrarily, thinking about how to run and how to run. Users have two ways to send transactions: a given sequencer pays a handling fee, requests packaging, and sends a deal directly to the miner. Whatever you do, it's ultimately up to the sequencer to decide the order in which the transaction is executed.
The capacity limit for each block is fixed, and a miner can include a limited volume of transactions in a block, so miners will first be included in transactions with higher fees, allowing those fee-paying transactions to fight for possible remaining space, and if you pay enough transaction fees, you can expect a miner to put it into the next block, but if the network is busy, you pay a transaction fee that is too low and may have to go through two or more blocks before the miner can record your transaction on the block chain.
The Electrum development team also warned them that they had nothing to do with a project called Electrum Dark: they used our name without our permission. Be careful with the altcoin version of Electrum, as they are sometimes used as vectors to install malware against your real Bitcoin wallet.
In a forum post on Bitcointalk, website administrator Theymos explained: "If at any time in the past you've logged in to Electrum without a wallet password and opened a web page, your wallet might have been stolen." Particularly paranoid people may want to send all bitcoins (BTCs) from their old Electrum wallets to the newly generated Electrum wallet. "
