Before I continue with a topic on strings, we first require some fundamental understanding of how memory works, i.e. what it is, how data looks in memory, etc. as this is crucial when we are analyzing vulnerabilities and exploitation. I highly suggest that your mind is clear and focused when reading the following article because it may prove to be confusing. Also, if you do not understand something, please verify all of your doubts, otherwise you may not completely understand when we touch on...

Hi everyone! In the previous part of this series we introduced remote code arbitrary execution via buffer overflows using all of our past experiences.
Welcome back, my rookie hackers! In my ongoing attempts to familiarize aspiring hackers with Linux (nearly all hacking is done with Linux, and here's why every hacker should know and use it), I want to address a rather obscure, but powerful process. There is one super process that is called inetd or xinetd or rlinetd. I know, I know... that's confusing, but bear with me.
We are living in a golden age of craft beers. Originally invented by the ancient Egyptians, every culture now has its own tastes regarding beer. The process of making beer is so multi-faceted, it's a miracle that any gets made at all.
When you're trapped at your desk before a jumble of data just waiting to be categorized, or zoning out during an important meeting, your mind wanders and, chances are, you feel a little guilty because of it. Yet you shouldn't try to reign in that distracted thinking. Instead, let your brain get distracted, and you'll unconsciously strengthen your memory.
Can you tell when your friends are serving up a bunch of BS, or are you constantly oblivious, unsure if they're spinning a valid story?

As sure as death and taxes, sitting at a wobbly table at one time or another is inescapable. With your weight on it, the table shifts from one end to the other, lifting one leg in the air and then the other; a parade of seesaws, especially if you have someone sitting on the other end.

You (or your partner, or both) are a Steampunk. Let's get away from all the mindless, unfeeling commercialism for a few minutes and think about dates instead of gifts—where do you take your significant other for Valentine's Day? What would be the ultimate Steampunk Valentine's Day date?
I've tried my hand in the past at defining Steampunk, but as anyone else who has made a similar attempt will tell you, there's a significant backlash from the community against working to create a real definition of what Steampunk is. That may sound ridiculous to some, but it's a very serious matter to others. With the recent announcement that TeslaCon 4 will be called the Congress of Steam, I think it's appropriate to talk about why all of this stuff is worth it. In this article, I'm going t...

This video explains about the rule of corresponding angles. When measuring the angle between the parallel lines (i.e.) Line1 and Line2 across the straight line. The angle A and angle B are equal. The angle C and angle D are equal. The angle E and angle F are equal. Finally angle G is equal to angle F. So, the angle between the parallel lines in all the angles are equal. Hence, this is the rule of corresponding angles. This video is very useful to basic high school geometry courses. Correspond...
This video explains how to use jumper cables to jump start a car. First, determine that a dead battery is the reason your car is not starting.

This video is about using the elimination method to solve a linear system. The lady presenting this video says that elimination method means that one of the two variables has to be eliminated while adding up the two linear equations. She then explains the example equations 6x-2y=66 and 5y=-29-2x. She asks you to first line up x and y. So the second equation is rewritten as 2x+5y=-29. Then she says that, to eliminate a variable, we should have their variables equal in value but of opposite sig...
