These harmful encryption extensions in Chrome are mimicking well-known encrypted wallets, including Ledger, Trezor, and Electrum. Ignorant users will only download these extensions, thinking they are downloading real encrypted wallet applications. Once they share private keys and other personal details, these malicious extensions hijack their cryptocurrency funds.

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.

According to the slow fog zone, the Phishing attack by Electrum forged upgrade tips has stolen at least 200 BTCs, and this attack cannot be avoided by upgrading Electrum alone, requiring the entire ecological service to make corresponding changes (because Electrum is not a full node, and then on the transaction broadcast and the corresponding server has a message communication, the attacker can also deploy a malicious server)
