The term ‘ethical hacker’ is often misrepresented as the keywords "ethical" and "hacking" are an oxymoron. A hacker is defined as an unlawful individual breaking into systems and obtaining private data without explicit authorisation. Society in general has a perception of a hacker as a person wearing a hoodie and hiding in a dark basement.
About a month ago I was chatting on skype to a colleague about a payload for one of our clients. Completely by accident, my payload executed in my colleagues skype client.
I decided to investigate a little further and found that the Windows and Linux clients were not vulnerable. It was only the Mac skype client that seemed to be affected. So I decided to test another mac and sent the payload to my girlfriend. She wasn't too happy with me as it also left the her skype unusable for several days.
