The attack comes in the form of links which appear on Deviant's pages and provides them with a link.... this link takes you to a fake DA login page. DO NOT and I repeat DO NOT enter your login and password here! If you do the attacker then has access to your deviant account.
So far the attack has been quite civil and thus only a minor annoyance, simply spamming other deviants.... but with access to a seemingly large number of deviants' accounts so far if it escalates there could be some serious damage done.
The links take the following forms (that I have seen so far)...
Check out this blog... link
A Valentine for you... link
I saw your picture on someone's blog... link
So please be careful with your account info and if you've already been 'hacked' be sure to change your password right away to avoid any major issues!
