Hackers launched a denial-of-service (DoS) attack on a well-known wallet Electrum server, according to Johnwick.io. Hackers used botnets of more than 140,000 computers to attack Electrum 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. De-dimensional Security Labs recommends that users of electrum wallets be updated to the latest version of the client through the official website and never use the link in the prompt message.

Bitcoin Wallet Electrum confirms a phishing attack against its users, reminding them not to download Electrum Wallet software from any channel other than the official website. Earlier media reports said Electrum users had maliciously stolen millions of dollars worth of cryptocurrencies. Hackers create Electrum wallet software with malicious code, induce users to download, and trick users into providing login information such as passwords to commit theft.

Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum Wallet is fast and has few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.

Popular Bitcoin wallet Electrum announced on the 8th, the server was a denial of service (DoS) attack, is studying the introduction of a more powerful version of the service network, affected users can not automatically connect, will manually choose to connect to the server.

Electrum 0.18.8 is available for details at github.

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.

Users of Bitcoin wallet Electrum are currently facing phishing attacks, according to Johnwick.io, a 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.

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.

If someone's Electrum wallet is connected to one of these servers and tries to send a BTC transaction, they will see an official message telling them to update their Electrum wallet, as well as a scam URL.

Once the solution has been selected, try an official example first. After writing a static file server, creating index.html, copying the code in the example into the running server, and a series of other operations, the expected augmented reality screen did not appear, and only one error page bounced out.

When broadcasting a transaction to a consensus node, Wave Idea actively indexes the transaction and replaces the transaction with a short byte identity code (SID). Therefore, by keeping all consensus nodes in sync and using SID when broadcasting blocks, wave ideas make it possible to super-compress blocks.
