Welcome back, my novice hackers! I've written a couple of articles on reconnaissance and its importance, and as I've said before, a good hacker will spend 3 to 4 more times doing reconnaissance than actually exploiting the system. If your recon isn't good, you'll likely fail, or worse—end up serving time and becoming Bubba's wife for a couple years. I can't say it enough—recon is critical.

Huh? If you are having trouble understanding central limit theorum and need help trying to solve it, check out this tu...

We will be translating the sentence "twice y differs from 5 by more than two, “into a mathematical equation. The word twice generally means two times, so 2*y (because y comes next in the sentence). Differs normally means is different and a difference from something in a mathematical sentence means subtraction most of the time, thus minus five. We don't know if we’re talking about below 5 or above 5 on the number line, so we put absolute value around the equation. More than implies a greater t...
In this tutorial the instructor shows how to find the x and y intercepts of rational functions. Finding the intercepts of a rational function is similar to finding the intercepts of other normal equations. You can find the x intercept of the equation by setting the value of y to zero and solving the equation. Similarly you can solve the y intercept by setting the value of x to zero and solving the equation. Now while solving this rational function for intercepts if you face a situation where ...

In this tutorial the author shows how to factor a number. He says that factoring means to find all the smaller numbers which can be multiplied to obtain the original number. He says that the number one and the number it self are the factors of every number. Now to find the factor of a number he starts with 2 and tries to divide that number with 2. If he is able to divide it, it implies that 2 is a factor of that number. He now does this with each and every number between 1 and the number it s...

As was mentioned by the great OTW last week, TOR, aka The Onion Router, has had its integrity attacked by the NSA. In an attempt to reduce the anonymity granted by the service, the NSA has opened a great many nodes of their own. The purpose is presumably to trace the origin of a communication by compromising some entrance and exit nodes. Once both are compromised, it is much easier to correlate traffic with a particular individual.
