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.

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.
