Two experts have presented a new critical vulnerability on Facebook platform, a zero day privacy loophole that they have named Deactivated Friend Attack The attacks occur when an attacker adds their victim on Facebook and then deactivates her own account. As deactivation is temporary in Facebook, the attacker can reactivate her account as she pleases and repeat the process of activating and deactivating for unlimited number of times. The real problem is the distracted behavior of users of social networks, too preoccupied to increase the counter of their relationships without carefully assessing the real identity of those seeking friendship.”]
