The electrum and Electrum-LTC versions below 3.3.3 are vulnerable to phishing attacks in which a malicious server displays a message asking the user to download the fake Electrum. To prevent user exposure, versions older than 3.3 can no longer connect to public servers and must be upgraded. Do not download software updates from sources other than electrum.org and electrum-ltc.org.
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. Electrum responded on Twitter that "this is a persistent phishing attack on Electrum users" and warned users not to download Electrum from any source other than the official website.
Electrum is a software wallet, which means that Bitcoin is stored in an encrypted file on our laptop or computer.

Lightweight Bitcoin Wallet Electrum announced that the next version will support Lightning network payments, implemented with Python, an electrum network node where wallet users do not need to run Lightning network nodes themselves to make payments, and electrum's Lightning network nodes have now been merged into the Electrum master branch.
You can download electrum Bitcoin Wallet on the official website "electrum.org". Electrum is also available to users of Ledger Nano S, KeepKey, and TREZOR hardware wallets.
Users of cryptocurrencies Wallet Electrum and MyEtherWallet are facing phishing attacks, according to posts posted on Reddit and Twitter on February 4. The MyEtherWallet team has issued a warning about phishing emails sent to users. Electrum also posted a warning on its website informing users that the electrum version, which predies 3.3.3, is vulnerable to phishing attacks. The company warned its users not to download software updates from other sources. (Cointelegraph)
Lesson 1: Third-party Electrum servers can link your two transactions together. This can be avoided by running your own Electrum server, supported by your own full node.
The Electrum team has announced the attack in an official tweet, saying that "this is an ongoing phishing attack on Electrum users" and reminding them to check the authenticity of the client's source before logging in. The team published its official website, and the Electrum clients downloaded elsewhere may be problematic.
