One evening, during the graveyard shift, an AOL technical support operator took a call from a hacker. During the hour long conversation the hacker mentioned he had a car for sale. The technical support operator expressed an interest so the hacker sent him an e-mail with a photo of the car attached. When the operator opened the attachment it created a back door that opened a connection out of AOL's network, through the firewall, allowing the hacker full access to the entire internal network of AO.
