Greg Price recently submitted an article to the Troy Messenger, You are what keeps me up at night:
Exploiting the human during a cyberattack is common. In fact, statistically, over seventy percent of the reported attacks in 2017, occurred due to human error. Approximately half of those successful attacks exploited the day-to-day end-user, the remainder were errors by the IT employees.
Attacking the human is successful, in part, because of human nature. Targeting the good nature, curiosity, and, eagerness of a person is simple. We want to help, we want to engage with technology.
