Hacking a Mac…

Hi everyone… 😛 This time I’m posting to bring you some useful information… If you have one of those 49$ external keyboards (not the laptop ones), then congratulations… Your computer is able to suffer the dullest hack ever!

Wait, what…? Apparently the external Mac keyboards micro-controller have some kind of firmware that leave room for the installation of rootkits and keyloggers by some hacker. Well, the operative systems are usually able to detect rootkits by several methods if they are examining the filesystem or a virtual machine. But how do you find a rootkit that is located somewhere else? Answer is: you don’t! These words are from “K. Chen”, the person who found this incredible failure in a computer security.

But does this only affect Mac’s? Well, as Mac loves to build software that is portable it works in every single operating system. The reason is simple… It is running over an external processor, that exists in the keyboard, with its own operating system that only sends characters to the other tip of the USB cable. So, all the computer can see is some bunch of data coming in and he puts it on the screen! I leave you with the video of “K. Chen” explaining and showing the actual hack. Also, you can find the original article here.

Passing everyone…

Posted in Education tagged , , , , , , , , , at 11:27 pm by sagito

Hi everyone… Today while reading some newspapers, I found a funny article about the education in Portugal. Apparently, some kid that frequented the eigth grade was constantly failing most of the disciplines that he had in that year (apparently he actually failed 9 in 14 disciplines). It is important to say that the kid has severe familiar problems and that this fact was pondered when the professors decided to… Pass him!

Ok, so let’s repeat this… There is a kid who failed almost everything he could fail and the professors decide to pass it to the next year! You can’t be serious… How far are we taking this game? Are we excusing the kid (who is actually also a victim of this case nevertheless) because it has familiar problems? I have problems, you have problems, everyone does! And just because we have problems,  the life gets it easier on us and we are able to pass through everything and everyone even if we don’t deserve it? I don’t think so…

The teachers attitude is irresponsible, to say the least. The kid is going to take a step he is clearly not prepared to, will feel out of place and perhaps even more frustated than if he had stayed in the 8th grade! Oh God, let’s please be real for a while… How is he ever going to make it through the life if the authorities are showing him that there is an easy way? For those of you who might be asking: I don’t know the rest of the problems that the kid have and I don’t care! Because I’m not against the kid, I’m against the teachers! I can’t help but feel sorry about the kid…

I feel sorry for this country, really…

You can read the whole article here (in Portuguese, but can easily be translated):
