Forum Thread: Some Questions.

1. By scanning
2. Yes, every system is hackable. What depends is difficulty.
3. Exploits in cross platform applications.
4. Loic is a dos tool. But pinging is not DoS.

-The Joker

1. I think there are tools (like NMap) that can see what is connected to the wifi
2. People will say that "iOS/OSX does not get viruses because its based on Linux". That is false. Its hackable, just some things, harder than others...
3. I think so...
4. Cross platform.
5. Google has an implementation that filters and/or blocks unusual requests. (making it difficult to take down.)

I will only address your last question as the others have been adequately addressed by the others.

There are many ways to DoS a system. Ping is just one way and it seldom works any more as nearly every secure network blocks ping. If your friend is trying to DoS Google, good luck to him!

thank you :D
