On the afternoon of December 20, a Twitter account belonging to the cryptocurrency exchange Etherdelta.com published a warning to its clients, imploring them not to use to the site until further notice. The platform has apparently determined that it suffered an attack, possibly several.
The message relates that one or more malicious actors gained access to the site's Domain Name System server, which would give them the ability to direct people intending to visit the authentic Etherdelta site to a website of their own.
MyEtherWallet, an online wallet service, said on its Twitter account that the exchange's clients should neither visit the site nor use it to unlock their wallets. The tweet seems to imply that the attacker or attackers may have spoofed the site, creating a visually similar mockup in order to trick users into entering sensitive information, which could be used to ultimately steal virtual currency from them.
