The real-life Angelina Jolie.
Twenty-year-old Omar Ramos-Lopez was an employee for an Austin-based car dealership until February of 2010, when he was let go from the company and his passwords were revoked. His former coworker's passwords, however, were not. This was a problem for the customers of the Texas Auto Center.
You see, part of Ramos-Lopez's job involved using a system a called WebTeckPlus to remotely turn off the cars whose owners were late on payments -- basically, there's a little box installed inside every car that, upon receiving a wireless signal, can disable the ignition system. You can see where this is going.
That is, nowhere.
Using someone else's password, Ramos-Lopez logged in to the system and shut down the cars of more than 100 random unsuspecting customers, who then proceeded to flood his former employer's office with angry calls since, you know, they weren't actually behind on their payments at all. Some of them even reported horns going off incessantly in the middle of the night, which was also within Ramos-Lopez's newfound powers and could only be stopped by going out and removing the car's battery. We're guessing that most of these people weren't even aware that something like this existed (we sure didn't) and assumed some sort of demonic possession was involved.
