When it comes to skill level, Script Kiddies are at the bottom of the totem pole and often use scripts or other automated tools they did not write themselves – hence the name. With only an elementary level of technical knowhow, Script Kiddies usually don’t cause much damage…usually. The Script Kiddy virus known as the Love Bug which sent out an email with the subject-line “I LOVE YOU” fooled millions of people, including some in the Pentagon, in the early 2000’s. The virus reportedly caused around 10 billion in lost productivity and digital damage.
Perhaps the scariest type of hackers are the ones that lurk within your own organization. Insiders are made up of disgruntled employees, whistleblowers or contractors.

Edward Snowden is a prime example of an insider who hacked his own organization – the US government.
