Attack on Facebook

The first thing the attackers did was take control of a small number of accounts on the social network. All of these accounts had friends. Using an automated access token theft technique, they started doing it with the accounts of these people's friends. Thus, this was done with more profiles on Facebook. At one point, they came to have 400, 000 accounts under their control.

They had access to information posted on the wall, groups, conversation names, and friend lists. Although there were 400, 000 accounts, they managed to end up affecting 29 million accounts on the social network. Since not in all cases have they had access to the same information in these profiles.

For 15 million users the name and contact details (phone number, email or both) could be seen. The remaining 14 million were victims of further data theft, including location or devices used to access Facebook.

Facebook has commented that the FBI is currently conducting an investigation. So it is possible that more information will come to light in the coming weeks.
