Couple of DNS servers were hijacked to resolve
http://myetherwallet.com users to be redirected to a phishing site. This is not on @myetherwallet side, we are in the process of verifying which servers to get it resolved asap.
Store your Ethereums and erc20 tokens on a hardware wallets like Ledger Nano S and Trezor and you are safe from them. Ofcourse, you need to keep your passphrase safe and away from internet connection. Im also keeping my tokens and Eth in a Ledger so I dont have any worries for these phising sites.
