In a blog post, Malwarebytes, an antimalware software company, said the number of infected Electrum Bitcoin wallets had reached 152,000 after the server was attacked by DoS, and the total amount of stolen funds had risen to $4.6 million, Cointegraph reported. The company identified a loader called Trojan.BeamWinHTTP, which also involved downloading previously detected Electrum DoSMiner. The largest number of robots are concentrated in Asia Pacific, Brazil and Peru, and botnets are growing to attack Electrum infrastructure.
Now, a lot of people are looking for alternatives to ElectrumX (original version), so we think this is a great opportunity to introduce some new options for running Electrum servers. Of course, we'll focus on Blockstream's Esplora, an open source blockchain browser bundled with a highly scalable Electrum server.
Public Electrum server.
Qtum Electrum synchronously updates electrum-related code and releases v0.18.9.
Bitcoin Wallet Electrum now supports Lightning Online Payments According to Coindesk July 11th, Bitcoin Wallet Electrum now supports Lightning Web Payments. It has previously been reported that Bitcoin Wallet Electrum has released a beta version of Electrum 4.0, adding support for the Bitcoin Lightning Network.
This technology has been in the industry for a long time. Connecting hardware to an all-node is also one of the key goals of the Electrum Personal Server project pioneered by developer Chris Belcher. He said in a project announcement last year.
The electrum and Electrum-LTC versions below 3.3.3 are vulnerable to phishing attacks in which a malicious server displays a message asking the user to download the fake Electrum. To prevent user exposure, versions older than 3.3 can no longer connect to public servers and must be upgraded. Do not download software updates from sources other than electrum.org and electrum-ltc.org.
You can use Security Seeds to recover your wallet on any Electrum client, even on the Electrum Wallet online web program.
Electrum Bitcoin Wallet is a reliable service that has been around since 2011. It is called a "thin" cold wallet, where the entire blockchain is not downloaded to the user's device but stored on a network server. In this case, the private key is stored encrypted on the user's computer and is never sent to the server.
The main reason for the Trezor vulnerability is that it does not have built-in multi-signature functionality, so its multi-signature implementation is to support Electrum extensions. This leads to an attack on Electrum, and Trezor is affected.
According to Bleeping Computer, the BTC wallet app Electrom accused a phishing product called Electrum Pro of stealing a user's seed key on May 9 on GitHub and registering a domain name called electrum without Electrum's permission. The Electrum team noted that there was a piece of code indicating that the counterfeit product might have taken the user's seed key and uploaded it to the electrum. Affected users should transfer funds from BTC URLs managed by Eletrum Pro.
At this time, the SPV-based Electrum wallet became the new favorite of Bitcoin players. Especially for small partners who are new to Bitcoin, editors recommend using electrum wallets.
Planet Daily News Electrum is a world-renowned Bitcoin light wallet with a long history of supporting multi-signatures and a very broad user base, many of which like to use Electrum as a cold wallet or multi-sign 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 a "message flaw" that allows an attacker to send an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing for the user, and if you follow the prompt to download the so-called new version of Electrum, you may get a trick. According to user feedback, because of this attack, stolen bitcoins are in the four digits or more.
The Healthy Security Lab is concerned that Nearly 250 bitcoins have been stolen in a recent hacking attack on an Electrum wallet. This attack, confirmed by Electrum, involves creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that "this is an ongoing phishing attack on Electrum users and advised users to download wallet apps from the official website" and that The Healthy Security Lab advised users not to install an unknown source of Electrum wallets to avoid being tricked.
Electrum's ElectrumX performs better than a personal Electrum server and includes a P2P exploration protocol that enables the wallet app of the average user to automatically find and connect to the server. These features make it a great solution for setting up public Electrum servers.
The text also explains that the implementation "relies on the Electrum server to query the channel state." In this regard, he added, "users must use servers they trust" because the server throws error messages about the state of the channel.
A new repo qtum-electrum-new was built to add qtum-related features to the latest code for Bitcoin electrum.
Electrum LTC wallet.
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.
Firewall-friendly: Electrum does not require a specific port in the firewall. It simply polls the server for updates.
Electrum is easy and fast to use. Your Bitcoin Electrum client does not need to download the entire data chain, only the download section can be used, which is based on the SPV principle proposed by Mr. Tsing. The designer will explain the design model of SPV in detail later.
You may have noticed an important difference between the MyMonero type and the Electrum seed type. MyMonero creates a viewing private key by hashing a random integer, while the Electrum type hash pays the private key. This means that the seeds of 13 and 25 words are not compatible - it is not possible to create an Electrum type account that matches the MyMonero type account (and vice versa) because viewing key pairs is always different.
Blockchain.info, Electrum Wallet.
According to the dimensionality reduction security laboratory (johnwick.io), hackers launched a denial of service (DoS) attack on the well-known wallet Electrum server. The hackers used a botnet of more than 140,000 computers to attack Electrum nodes and deployed malicious nodes at the same time . When users connect to these malicious nodes and use the old version of Electrum to send transactions
