Right. That's a trick cons use. They usually spoof bank sites, e-bay, and other financial sites. The email looks just like it came from the legit outfit, but redirects to a phoney site that collects the info. The collection site looks like, or similar to, the real one. Some are better than others and the better ones can't be traced easily, because they hijack personal pcs to cover their tracks and the main outfit is located in the land of podunk.
They spam billions and make a profit on the small percentage of folks that fall for the con and give them the requested info. No one at the DNC did this and if there's anything to it, there will be more than 1 complaint.
