Hackers: The Internet's Immune System

For most of us, when we think of hacker, we think of cyber criminals. But hackers my actually be the ones protecting the internet. "Sometimes, you have to demo a threat to spark a solution" is said by Jack Barnably, the person who figured out how to make ATMs throw money at him. Hackers are the ones who can easily find the little things that can break and force us to fix it.
For example, there was one hacker who realized that he was able to hack into wireless wifi routers and print out all the data from it online. He thought that this was a problem and notified the company about it. However, the company didn't do anything, thinking that it was just how things were done with routers. So two months later, a couple of hackers hacked into another wireless router but they didn't steal anyone; in fact, they left a note warning the user that they were vulnerable and their information can be accessed by anyone with an internet connection. They even gave to list of people who are also vulnerable. They were nice enough to even leave a URL to a news article telling them how to better protect themselves. In a way, hackers are like Robin Hood, they are superheros with a bad name (and also does illegal acts).
