ICYMI from Def Con: Security researcher Eaton Zveare found bugs in a carmaker's centralized dealer web portal's login flow that allowed "unfettered access" to customer data and systems inside. The portal allowed the remote controlling of some car functions, like door unlocking.

Zveare said the bugs, now fixed, highlight the risks of these web-connected data portals that contain gobs of customers' data.
