So the DNS attacks are starting. Unfortunately the distributed nature of DNS means people may well get affected if their ISPs haven't been paying attention. The upshot is it is very possible that you will get sent to a site that may look like what you wanted but is actually what you thought it was.
Typically these rouge sites either install malware, steal passwords or serve up advertising. As I noted earlier SSL can help mitigate things by proving the server you are talking to really is the one you think it is. So for now you should still be safe connecting to your bank (assuming you've not mistyped it or been re-directed under a cloak). That is of course assuming no one uses the same passwords on their bank account as they do on LiveJournal.
