On a fundamental level this is how it works. Your computer, or computer system, is full of access points (doors). For example, a house has a front and back door, a garage door, and windows. A burglar trying to get in will use the easiest way possible but a diligent homeowner has locks and security system. Just like computer/systems have firewalls and security software. A hacker trying to hack a computer/system will first try to gain entry through the front door. When that doesn't work, they try the back door. If that doesn't work, the windows. It's hard to keep track of every single access point, so a window may be unlocked, giving the burglar/hacker access to the computer/system. Houses have usually less than a dozen access point. Computers have far more, so much so, that it is essentially impossible to have a 100% secure computer/system. Even if all the doors are locked, I can trick you into opening the front door. Or when you decide to leave your house, I can sneak in while the door is open. There are so many ways to hack/burglarize a house/computer/system.

That's it in a nutshell.

LOL it would have been a lot better if you compared the house entries to actual computer entries, but whatever. thanks anyway

Thats a pretty good description, except that most of the time its more like "they forgot to build a wall there and it also happened to be the wall that lets you into the locked vault"


Its deadly easy if you know how to find exploits in systems. Its not even malicious knowledge half the time. When you work in computers, especially in web development you know how to do it cause you are trying to make it so no one else can do it.

He's talking about software "doors", not physical like usb-ports.

yea i know that.

he could have still given examples of how to gain access through computer programs.

sure we're talking about dropping keyloggers, viruses, trojans, blasters, and et cetera et cetera et cetera ....

but i think slylee is wondering about how does a hacker able to access a password protected computer system not through an internet entry way? we could be talking about brute forcing your way or accessing a computer via an administrator / root account / group.... there are so many different ways to access a computer system like Krypton said via internet / non-internet.

One of the most common exploits outside of website hacking (which is way easier) is called a buffer overflow.

In certain computer languages sometimes input taken from outside the application is longer than what the application assume it will be.

Instead of truncating that input it will put it into memory.

The problem is that it puts whatever is overflowing the assigned length up into a different part of memory. In certain cases that memory is memory that will be the place instructions are stored before they are sent to the processor to be executed.

So a inventive person will feed in data longer than the lengths expected and put malicious code after that. That malicious code is then in the memory that is executed and it will be carried out.

What this code does most of the time is either install itself into the system and then after that it creates a hole for it to gain more access or allow others to gain access to the system.

Lots of applications have had these holes in the past. One of the most famous was the Blast Worm from a few years back.

Your computer could be sitting exposed directly to the internet. Lots of services are exposed in Windows to the internet (not so much anymore actually) and they could be used to compromise your computer.

If you sit behind a firewall or even a basic NAT router then you are probably safe.

ok i had to read it twice but i think i get it. and this can be done how? by the hacker sending a link to you via email or chatting?

and would the link be a bogus one or a legit one that he just added code to that will be stored in my memory?
