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.

When we can ensure the most important functions of the financial network through computer science instead of traditional accountants, regulators, investigators, police and lawyers, we choose an automated, global and safer system instead of a manual, local and inconsistent security system. When cryptocurrencies run correctly on the public chain, they can replace a large army of computer bureaucrats. Computers on these blockchains allow us to put the most important components of online protocols on a more secure and reliable basis, making it possible for interactions that we were afraid to do on a global network before.

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.
According to The Next Web, the attackers even implemented their own Electrum servers, which hosted the attacked Electrum.
According to Johnwick.io, we will continue to monitor and track the further flow of funds after a recent user submitted a coin-losing incident claiming that the download used an Electrum wallet had been phishing and that more than 700 bitcoins had been lost, and that the stolen address had been added to the Devi AML system.
