While some of the hackers in the world are interested in killing as many birds as they can do with one stone, while others think like snipers and are determined to take down one high profitable target with the most advanced precision as quickly as possible.
Over the last few years, there has been a rise in the number of reported targeted attacks. Targeted attacks are much harder to detect than the widespread attacks.
