20-minute Intro to Hacking

- It’s very easy to be caught. Even the most sophisticated hackers get caught. See for example Kevin Mitnick, Jeanson James Ancheta, and Albert Gonzalez.
- The penalties for unethical hacking are steep. The above listed hackers all spent at least 5 years in prison (Albert Gonzalez is currently serving 20). Also, once you are convicted of a computer crime, it is very difficult to get a job having anything to do with computers. Employers will be scared of you. Furthermore many ethical-hacking jobs (mostly in the government) will require that you take a lie detector test, and they will ask if you have committed computer crimes.
- There are great rewards for being ethical. For example, if you figure out how to hack Google (using ethical techniques) you can tell Google how you did it and they will give you a reward as much as $20,000. There are also lots of high-paying jobs for ethical hackers.
- Never hack someone’s system without their permission
- If you identify a way to hack someone’s system you should tell them so they can fix it. Once they fix it, you can publicize your hack and earn respect from other hackers (and employers).
- Hacking is fun. That’s probably the number one reason ethical hackers hack. But it can also be very lucrative, as I mentioned in this last slide. This slide tells you how can you make money as an ethical hacker..Hopefully, you’re dying to know “How do I hack!?” It’s like hot wiring a car. To hot wire a car, you simply cut into the right part of the car, find the right pair of wires, and connect them together. It’s actually very simple once you know how a car works. I would wager that every good auto mechanic knows how to hot wire a car. Once you know how a car works, hacking the car is pretty obvious.
Hacking computers is similar. Once you know how a computer works, hacking is often pretty simple. Hacking only seems mysterious to people who don’t know how computers work. One of my favorite all time quotes is:
Any sufficiently advanced technology is indistinguishable from magic.
Though, I would actually say “Any technology you don’t understand is indistinguishable from magic.” Once computers are no longer magic, you realize they are simply machines that can be manipulated just like any other machine you understand.
- Computers talk to each other kind of like the way people talk to each other.
- For example, I could ask you “What’s 2+2?” (the request), you could calculate that and give me the answer (the response).
- Going farther with this analogy, let’s imagine there is a group of people gathered in a room. Every person in the room represents a computer. One person represents a “server,” which is simply a person (or computer) that receives requests, calculates results, and sends them back as responses.
- All the other people are “clients,” which are simply people (or computers) that give requests to servers.
- The one person designated as the server will do math problems for you if you request it.
- The server can only work on one math problem at a
time. The clients take turns asking the server to do math problems.
Let’s think about hacking the server. Is there a way you could crash the server? Could you send a math problem to the server, that clogs it?
If you ask the server “What’s 3278398457234 divided by 93672511″ I bet it would take a very long time for the person to calculate the result. And since the server can only work on one problem at a time, all the other client’s would be ignored while the server is working on that one really hard problem.
then next ucan crash computers like anything!
i will continue it in my next post....dudes.
