Several Facebook employees successfully hacked the password of a senior engineer as part of a challenge to test the security of the site's administrative system. In order to do it they employed an evil twin wireless attack.
Instead they went straight to the place where he was most vulnerable, at home. There the "hackers" instrumented what is known as an evil twin attack. They installed a rogue access point, duplicated the settings of his wireless network - same SSID, same channel - and waited.
Being in the comfort of his home and with his guard down, Keyani logged into the rogue access point without realizing anything was wrong. Unfortunately, his colleagues had a traffic snooper installed on the AP, which captured everything, including his Facebook password in plain text.
