Hmmmmmmmmmm....

Mine is still pointing to secure.4rx.com over here. Interesting that you are getting something different.
From BigVern on Cryptsy's Chatbox:
BigVern: @erpbridge: whoever made those screenshots prob has a virus then
....so I suggest you guys go get your virus scanners fixed.
What does he say about the invalid certificate warnings regarding other domains, namely:
professionalperformanceonline.nl
secure.4rx.com
which several users here reported and which resolve to IPs associated with Incapsula.com, the DDoS mitigation service crytpsy are now apparently using as well?
If he thinks a virus is the most probable explanation then cryptsy needs a new security team. This should be fully resolved in cooperation with Incapsula, immediately, and a full attack mitigation statement and impact report be published here and on the site if there is any interested in maintaining a base level of user trust. The site doesn't even offer two-factor authentication and now a potential MITM is about to be swept under the "must be a virus" rug?
And nobody should login before any of that is resolved
