“Trusted Contacts is a system created by Facebook to help you gain access to your account if you forget your password or your account is locked. If you enable Trusted Contacts, Facebook will ask you to identify three to five people. If you need access to your account, Facebook will send part of a code to each of these users that can be combined to gain access to your account.”
The attacker asks for victim’s help recovering his account, he tells the victim that he is as one of his Trusted Contacts on Facebook, and inform him that he will receive by mail a code for recovering their account.
The attacker, who is posing as a victims’ friend thanks to the compromised account, asks the victim to share the recovery code.
