will catch anyone they can when they are sending
out most attacks, but there is no size limit for them.
Targeted attacks, often called spear phishing or whaling,
may be directed at an individual high value target such
as a system administrator or C-level executive. Targeted
attacks may be customized for the victim and are more
difficult to spot. They are less common due to the
additional effort required.
