The attack happened on the exact Etherdelta website where there was temporary access to Etherdelta's DNS server by the hacker. It was the exact Etherdelta domain not like this usual phishing attempts you know of where there is a slight alternation of the domain name.I was starting to do a token transfer at that time of the attack so yes, I was doing something on a correct url of a website whose DNS server had been hijacked. If it wasn't for Netcraft and MetaMask's alerts. My funds were gone.
This is not an ordinary phishing attempt we always see daily. We are talking about a DNS server getting hijacked.
