A helpdesk technician received a phone call from an administrator at a remote branch office. The
administrator claimed to have forgotten the password for the root account on UNIX servers and
asked for it. Although the technician didn’t know any administrator at the branch office, the guy

sounded really friendly and since he knew the root password himself, he supplied the caller with the
password. What type of attack has just occurred?

A.
Social Engineering attack

B.
Brute Force attack

C.
War dialing attack

D.
Replay attack
