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)

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.

Note that the above is certainly not a charge against the client browser Javascript;

Verge also said it had reconsidered the Electrum spectrum and was working on porting the latest ElectrumX server to work with the Verge Core client. "This means that you must upgrade the Electrum client after it is published. Doing so will indicate that you support the new halving schedule. "According to the previously announced timetable, the halving is planned for block 3700,000. (Newslogical)

Javascript?

Javascript?

The big reason for this significant increase is that JavaScript is almost everywhere. For client domains, you can use things like Angular, React, and Vue.

Before I begin, I want to solve some problems. IPFS clients have two implementations, one in JavaScript and the other in Go. JavaScript seems to be the best choice here, but because it was developed earlier than the Go client, it was not the best choice. We'll use the Go client and connect to Node through its API.

Due to the lack of standardized module systems in browsers in the early 2010s, CommonJS has also become a popular module format for JavaScript client libraries.

This "update tip" is not an official act of Electrum, but a phishing attack by an attacker that exploits a message flaw on the Electrum client and the ElectrumX server, which requires the attacker to deploy the malicious ElectrumX server in advance, and the malicious server is localized by the user's Electrum client (because the Electrum client is a light wallet and the user needs the ElectrumX server to broadcast the transaction). At the time of the madness, malicious ElectrumX servers accounted for as many as 71% of the total, and the show doesn't fully count that hundreds of bitcoins have been stolen in this phishing attack over the past year or so.

Johnwick.io found that hackers launched a denial-of-service (DoS) attack on a well-known wallet, Electrum server. Hackers used a botnet of more than 140,000 computers to attack Electrum's nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials. Devi Security Labs recommends that users of Electrum Wallet update to the latest version of the client via the official website and never use the link in the prompt message.

At around 3 a.m., Lightning web developer Alex Bosworth tweeted a quote from Bitcoin client Electrum developer Thomas.

In December 2018, Slow Fog first discovered and alerted an attacker to a messaging flaw using the Electrum wallet client, forcing an "update prompt" to pop up during a user's currency transfer operation, inducing users to update and download malware to carry out a currency theft attack, according to Slow Fog. Although electrum officials said in early 2019 that some security mechanisms would be in place to prevent this "update phishing", many users of Electrum are still in the old version (less than 3.3.4) and the old version is still under threat. However, we do not rule out a similar threat to the new version.

According to the Dimensionality Reduction Security Lab, users of Bitcoin wallet Electrum are currently facing phishing attacks. The hacker broadcasts a message to the Electrum client through a malicious server, prompting the user to update to v4.0.0. If the user installs this "backdoor client" as prompted, the private key will be stolen and all digital assets will be stolen

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.
