All About Lightning Electrum
The Electrum development team also warned them that they had nothing to do with a project called Electrum Dark: they used our name without our permission. Be careful with the altcoin version of Electrum, as they are sometimes used as vectors to install malware against your real Bitcoin wallet.
Bitcoin Wallet Electrum has released a 4.0 beta version with new updates that support Lightning Networks and more.
In December 2018, Slow Fog first discovered and alerted an attacker to a messaging flaw using the Electrum wallet client to force an update prompt to pop up when a user transfers money, inducing users to update and download malware to carry out a currency theft attack. Recently, slow fog technology anti-money laundering (AML) system through continuous tracking found that one of the attackers wallet address bc1qc... p2kny has stolen more than 30 BTCs for six months and has been active recently. Slow Fog alerts Electrum users to update prompts, the new version of Electrum in this update prompt is likely to be false, if installed, please promptly transfer Bitcoin out in another security environment. At the same time, slow fog called 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. This update tip is a phishing attack by an attacker who 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 according to incomplete statistics, hundreds of bitcoins have been stolen in this phishing attack over the past year or so. Although in early 2019 Electrum officials have said they want to 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 old version (less than 3.3.4), the old version is still under threat, but slow fog does not rule out that the new version will have a similar threat.
Currently, hardware wallets like Trezor and Ledger are considered the safest way to store bitcoins because they can be unlocked offline to protect keys from online theft. However, one limitation of hardware wallets is in terms of software engagement because they are not compatible with different software. Trezor, for example, supports only software wallet Electrum, not other wallets like Bitcoin Core.
Electrum tweeted today about the incident, saying it was "a persistent phishing attack on Electrum users" and imploring users to check the effectiveness of the resources they log on to.
BW's mining platform was established in 2014 to offer a wide range of Bitcoin mining products and services on the same platform. These products and services include mining chip development, mining pools, Bitcoin cloud mining, and interest-bearing wallets.
How do you use it? Suppose A is going to give B 1 Monroe coin. Then A's wallet will use B's two public keys.
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.
Bitcoin Wallet Electrum has released a beta version of 4.0, adding several updates that support lightning networks, 000, and more.
