Recently, some users of Bitcoin Light Wallet electrum have been targeted by a phishing window attack, which prompts users to fail to transfer money using electrum Light Wallet, and also directs users to the specified address to download the "latest version" of the wallet

According to Reddit user u/normal_rc, electrum's wallet was hacked and nearly 250 bitcoins (243.6 BTCs, nearly $1 million) were maliciously stolen, according to coinelegraph. Electrum then confirmed that the attack included creating a fake version of the wallet to trick users into providing password information.

According to Bleeping Computer, the BTC wallet app Electrom accused a phishing product called Electrum Pro of stealing a user's seed key on May 9 on GitHub and registering a domain name called electrum without Electrum's permission. The Electrum team noted that there was a piece of code indicating that the counterfeit product might have taken the user's seed key and uploaded it to the electrum. Affected users should transfer funds from BTC URLs managed by Eletrum Pro.

However, after electrum officials said in early 19th that some security mechanisms should be put in place to prevent this "update phishing", many users of Electrum are still in the old version.

Electrum is free software used by many cryptocurrencies websites, including merchants and exchanges, to store bitcoins.

Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Devi 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. DeViable 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 Electrum 3.3.8 via the official website (electrum.org), which has not yet been officially released, and do not use the link in the prompt to avoid asset losses.

It's not hard to run your own Electrum server and point your wallet to just use it. This restores Electrum to the point where it has the same privacy and security attributes as the full node, where no one else can see the address or transaction that the wallet is interested in. Electrum then becomes an all-node wallet.
