According to The Next Web, the attackers even implemented their own Electrum servers, which hosted the attacked Electrum.
how long does it take to send bitcoin from coinbase to electrum
Coinbase announced that its wallet Coinbase Wallet supports the use of human-friendly short addresses to send cryptocurrencies, including .eth addresses that support Coinbase Wallet username addresses and Ethereum Name Services (ENS), and that users who do not have a .eth address can also purchase their .eth addresses by visiting the ENS website through the wallet's dapp browser. At the same time, it is easier for users to send encrypted assets back to Coinbase from Coinbase Wallet. Coinbase also provides a privacy option to keep a user's username private or to make it private in the Wallet app so that other users cannot search for that user's username address.
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.
Because you can send cryptocurrencies from other platforms to an exchange like Coinbase at any time, Coinbase does not know when, where, or at what cost the cryptocurrencies you receive, coinbase can only receive the assets and therefore cannot generate previous tax records.
To put it simply, the problem with zero proof of knowledge is how do I know that I do know this thing without knowing if I know it.
To use mnomets to transfer addresses from electrum wallets to web wallets, you need to set Electrum to be compatible with Qtum phone mnomets in the initial installation (and then use phone wallet mnomets to restore phone wallets on Electrum). This setting is screenshot of the Electrum configuration.
Bitcoin Wallet Electrum releases Selectrum 4.0 beta support for the Lightning Network.
It's not hard to run your own Electrum server and point your wallet to just use it. This restores Electrum to the point where it has the same privacy and security attributes as the full node, where no one else can see the address or transaction that the wallet is interested in. Electrum then becomes an all-node wallet.
Users of Bitcoin wallet Electrum are facing phishing attacks, according to Johnwick.io. 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.
