Select Wallet - "Private Key" - "Export" on the Electrum wallet and you will export the file qtum-electrum-private-keys.csv or copy only one private key. Select Recover from WIF on your web wallet, paste the private key, and select Confirm. Check that the wallet address is correct. You may need to use Dump as a Key File to save the key file.

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.
In the end, you've completed your first transaction with the Electrum Wallet.
