The Bitcoin desktop wallet client Electrum has released a beta version 4.0, which adds support for several important updates such as the Lightning Network. This version is nearly a year away from the previous version of Electrum 3.3.8 (July last year)

We've also gone through the telecommunications era of cable telegrams, radios, cable phones, wireless phones (the world's first mobile phone was invented by Motorola engineer Martin Cooper in 1973), and we've also gone through the era of computer Ethernet, the era of computer phone dial-up Internet access, the era of computer ADSL Internet access, the era of computer Wi-Fi Internet access, the era of mobile Phone Wi-Fi, mobile phone 2G/3G/4G Internet age.
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.
Bitcoin Gold (BTG) halved its third block at a block height of 630,000 and is expected to reduce the block reward from 12.5 BTG to 6.25 BTG on April 18.
Now that we understand the benefits of Electrum, we can start using Electrum. Before use, prepare pens and paper to facilitate the recording of safety seeds.
In August-September, Bitcoin wallet Electrum was hacked twice, and according to multiple sources, at least 1,450 BTCs worth $11.6 million were stolen from phishing attacks that faked Electrum upgrade tips.
Nadav Ivgi announced the alpha version of the Bitcoin Wallet Tracker (BWT), which uses its standard RPC interface to interact with Bitcoin Core wallets, uses the data to build additional indexes needed for lightweight wallets, and then makes the data available through the Electrum Server protocol and BWT's own HTTP-based APIs. Similar to Electrum Personal Server, this allows users who prefer lightweight wallets, such as the Electrum user interface, to retrieve blocks and transaction data from their own full authentication nodes for additional security. In addition, BWT's approach has no significant overhead, and its additional indexes are stored only in memory, and in many cases it can handle crop nodes, allowing the combination of bitcoind and BWT settings to use only a few gigbs of disk space.
In this demo, Electrum developer Chris Belcher shows how to set up and use an Electrum personal server.
Options currently have less domestic historical data, so the overall use of millions of APIs is enough to meet the demand, do CTA strategy research will export csv format data from MC and then read to Python, is currently studying the interface of the link, for no other reason: convenience and cost-effective.
This isn't the first time electrum has appeared in a fake version. In December, nearly $1 million of BTC was stolen when hackers developed a fake encrypted wallet, Electrum. 1 this year.
Digital wallet developer Electrum has released an emergency patch saying it found a vulnerability that could lead any website hosting Electrum to steal a user's digital currency, exposing passwords to the JOHNSONRPC interface and ingelling hackers full control of the wallet. Earlier, Electrum released the first patch, but it didn't seem to solve the problem, and they released a second update urgently Sunday night local time.
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.
The Electrum team has announced the attack in an official tweet, saying that "this is an ongoing phishing attack on Electrum users" and reminding users to check the authenticity of the client's source before logging in. The team published its official website, and electrum clients downloaded elsewhere may be problematic.

Bitcoin Wallet Electrum users face phishing attacks, and when a user updates a client with a backdoor, the private key is stolen and 1450BTC has been stolen so far.
