Electrum Personal Servers (EPS) do not perform as well as ElectrumX or Electrs, but are easier to set up and connect to Bitcoin nodes, making them a good choice for those interested in installing private Electrum servers. Compared to fully indexed ElectrumX or Esplora instances, it is less hardware-demanding and therefore can run on normal devices.
A: There are too few nodes for electrum server, and there are only 210 site statistics, making the hacker's malicous server highly likely to occupy all nodes linked by the user.

Enter the following command to connect to the api server for later instruction sending operations.
Attackers reportedly created their own Electrum servers, which hosted the attacked version of Electrum in order to implement the attack. When the user will be vulnerable.

Connect to the BERT server using an IP address; If it is a machine server, you do not need ANPs.
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 a message flaw that allows an attacker to send update prompts through a malicious ElectrumX server. This update prompt is very confusing for 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. This captured currency theft attack is not stealing the private key (electrum's private key is generally stored with two-factor encryption), but replaces the transfer destination address when the user initiates the transfer. Slow fog reminds users that when transferring money, special attention needs to be paid to whether the destination address is replaced, which is a very popular method of currency theft recently. It is also recommended that users use hardware wallets such as Ledger, and if you pair it with Electrum, although the private key does not have any security issues, you should also be alert to the replacement of the destination address.
The discoverdomain function can be run by sending backdoor commands or automatically. Discoverdomain first enumerations the electrum Bitcoin wallet server using a public list, and then tries to query history with a hard-coded hash.
Hackers have launched a denial-of-service (DoS) attack on a well-known wallet Electrum server, according to Johnwick.io. 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.

Users of Bitcoin wallet Electrum are currently facing phishing attacks, according to the Devi Security Lab. Hackers broadcast messages to electrum clients through a malicious server, prompting the user to update to v4.0.0, and if the user is prompted 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 (stolen by one user, antimalware firm Malwarebytes and Electrum) had been stolen in phishing attacks that faked Electrum upgrade tips, with a total value of approximately $11.6 million. It is worth mentioning that electrums below version 3.3.4 are vulnerable to such phishing attacks, and users of Electrum wallets are requested to update to the latest version of Electrum3.3.8 via the official website (electrum.org), which has not yet been officially released, and do not use the links in the prompts to avoid asset losses.
In addition, Ivgi provides a plug-in that simplifies the process of setting up BWT with the Electrum client, and can also be used with other wallets that support the Electrum server protocol, such as Edge, Blue Wallet, Eclair Mobile, and Phoenix.
Chris Belcher is understood to have created and maintained private open source software for Bitcoin, such as CoinMarket and Electrum Personal Server, it said.
Verus Desktop Wallet is the first GUI application to support the Verus ID protocol, as well as a full-node wallet for KMD ecosystem tokens, based on BTC's Electrum server and Ethereum/ERC20 tokens. The wallet also includes an intuitive mining/pledge interface that displays estimated revenue forecasts as well as private transactions/messages.
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.
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.
In December 2018, for the first time, we discovered and alerted an attacker to a messaging flaw that exploited the Electrum Wallet client to force an "update prompt" to pop up when a user transfers money, inducing the user to update the download malware and then carry out a currency theft attack. 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. Although in early 2019 Electrum officials said they would adopt some security mechanisms to prevent this kind of "update fishing", such as: 1. Patch Electrum client does not display rich text, does not allow arbitrary messages, only strict messages; Patch ElectrumX server implementation detects Sybil Attack (i.e. witch attacks, malicious servers that send phishing messages) and no longer broadcasts them to clients; Implement blacklisting logic to alert malicious servers outside the Electrum client view; Promote social networking sites, websites, and all forms of communication that exist with users, who should always run the latest version and always only install from official sources (electrum.org), access through security protocols (https), and verify GPG signatures in advance. However, many users of Electrum are still in the older version (less than 3.3.4), and the older version is still under threat. However, we do not rule out a similar threat to the new version. Recently, slow fog technology anti-money laundering (AML) system through continuous tracking found that one of the attackers wallet address bc1qcygs9dl4pqw6atc4yqurzd76p3r9cp6xp2kny has stolen more than 30 BTC, the crime lasted six months, and recently is still active. We would like to remind Electrum users that the new version of Electrum in this Update Tip is likely to be false and that if installed, transfer Bitcoin out in another security environment in a timely manner. At the same time, we call on the vast number of cryptocurrencies exchanges, wallets and other platforms of the AML wind control system black and monitor such as the above Bitcoin address. Finally, identify electrum's official web address.
According to Bleeping Computer, the Bitcoin wallet app Electrom was on GitHub on May 9th, accusing a phishing product called Electrum Pro of stealing a user's seed key 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 Bitcoin URLs managed by Eletrum Pro.
