Over the last 20 years the technology has developed loads so thre have been more incidents then ever in these past 20 years.
Hacking started around the 1950-1960's which sent more and more company's down.
Hacking costs large companys (microsoft) around 46.8 Billion every year.
The 14-year-old from Tallaght was responsible for millions of computer users being alerted after the popular online game Modern Warfare 2 was hacked.
For example a 14 year old boy who hacked into microsoft who costed them billions have now gave him a job to try and get how he got into microsoft to make them a better company.
Another example of what a hacker can do is with the case of Gary McKinnon a 45 year old British man who managed to hack into the pentagon
data base.
He was looking for evidence of aliens that he thought landed on earth he is autistic.
"It was a silvery, cigar-shaped object," he repeatedly said. "There were no visible seams or riveting. The object didn't look manmade or anything like what we have created."
He was born in Glasgow in 1966, but grew up in London with his mother Janis and stepfather Wilson, a UFO fan.

The row over phone-hacking by journalists has led to the closure of the News of
the World newspaper, the establishment of the Leveson Inquiry, an MPs' inquiry
and the launch of three police investigations.
More than 4,000 people have been identified by police as possible victims of
phone hacking by the Now.
I think hacking is bad because people doing it and sometimes do it by accident which means its to easy so the company need to put more safety around there network.
