First, Electrum implemented its own Lightningwatch watchtower, an important part of the Lightning Network, which scans the Bitcoin blockchain to detect and prevent fraud.
In recent days, hackers or hacker groups have stolen more than 200 bitcoins worth about $750,000 by attacking the infrastructure of electrum Bitcoin wallets. The attacker is targeting Electrum.
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.
The slow fog area said that the phishing attack that allegedly forged the upgrade prompt had stolen at least 200 BTCs, and that the attack could not have been avoided by upgrading Electrum alone, requiring the entire ecological service to make corresponding changes (because the Electrum client is not a full node, and then has a message on the transaction broadcast and the corresponding service side, the attacker can also deploy a malicious server). Slow fog zones remind users that phishing attacks like Electrum require long-term vigilance. The slow fog zone has previously issued an alert for selectrum phishing updates, and hackers who attacked Electrum wallets used Electrum's software to unusually construct malicious software update prompts to induce users to update and download malware usage.

Earlier this month, Electrum detected a DoS attack on its network, allegedly launched by a malicious botnet with more than 140,000 machines, designed to provide Electrum to users.
The developers of Bitamp Bitcoin Wallet have created an easy-to-use client open source Bitcoin wallet to meet this demand. Bitamp Wallet allows users to send and receive bitcoins anywhere, on any device. The interface also allows users to create a new Bitcoin wallet in an instant by writing down a 12-word seed. Users who generate seed phrases on other platforms such as Electrum, Mycelium, and Ledger can access their bitcoins anonymously and securely through the Bitamp site.
Popular wallet developer Electrum has released an emergency patch for a key vulnerability in Bitcoin wallets.
What if I already have Test Flight's original iOS wallet (downloaded), 12-word seed, and updated the new version, entered my 12-word seed without showing the money?
If you have an old computer you don't use, you can make an electrum cold wallet from an old computer.
The cryptocurrencies wallet Electrum was hacked and lost 250 bitcoins.
The effect of this is that each block has a 256-bit clear text random seed, and for the node out of the block, but also the future of their own packaging of the next random seed in advance to determine, so that others do not know what the future random number seed is, but does not affect the future other nodes can verify the random number seed, which ensures that no one can control the generation of random seed.
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.
Electrum is one of the most popular Bitcoin wallets and now supports Lightning Network payments.

Lightweight Bitcoin Wallet Electrum announced that the next version will support Lightning network payments, implemented with Python, an electrum network node where wallet users do not need to run Lightning network nodes themselves to make payments, and electrum's Lightning network nodes have now been merged into the Electrum master branch.
Electrum LTC Wallet is a desktop-based cryptocurrencies wallet that supports Litecoin. Here are some aspects of wallets: Like its predecessor, Electrum- Bitcoin Wallet, open source wallets can be found on GitHub, where anyone can view or upgrade codes.

Users of cryptocurrencies Wallet Electrum and MyEtherWallet are facing phishing attacks, according to posts posted on Reddit and Twitter on February 4. The MyEtherWallet team has issued a warning about phishing emails sent to users. Electrum also posted a warning on its website informing users that the electrum version, which predies 3.3.3, is vulnerable to phishing attacks. The company warned its users not to download software updates from other sources. (Cointelegraph)
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.
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-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 "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. 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. Here we remind users that when transferring money, special attention needs to be paid to whether the destination address has been 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.
In this demo, Electrum developer Chris Belcher shows how to set up and use an Electrum personal server.
Electrum-LTC is a simple but powerful Litecoin wallet. The platform is also known as the Lightweight Litecoin Client.

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. As of 13:00, at least 1450 BTCs worth approximately $11.6 million had been stolen from phishing attacks that forged Electrum upgrade tips. Devi 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 Electrum3.3.8 via the official website (electrum.org), which has not yet been officially released v4.0.0, and do not use the link in the prompt message to avoid asset losses.
We will continue to monitor and track further movements of funds after a recent user submitted a coin-losing incident claiming that the download used an Electrum wallet had been phishing attack, losing more than 700 bitcoins, and that the stolen address had been added to the Devi AML system. It is reported that malicious website (electrumsecure) fake E) fake Electrum website to carry out phishing attacks, guide users to download and use the wallet, in order to steal the user's private key and other sensitive data. Devi Security Labs is here to remind users not to install unknown sources of Electrum wallets, to avoid asset losses.

By default, electrum wallets are randomly connected to a set of Electrum servers. From a privacy perspective, this is not a good thing because it discloses your wallet address and balance to unknown third parties. And unfortunately, many public Electrum servers are run by individuals or groups of blockchain analytics companies or worse. Therefore, if you are using an Electrum wallet, it is generally recommended that you run your own Electrum server and then connect the wallet to that server.
Lightning support in Electrum has been around for a long time. Thomas Voegtlin, the founder of Electrum, first told CoinDesk last summer that Lightning would take it to the next version.
