Hi everyone! In the previous part of this series, I introduced one way to hijack a program's execution flaw, though I only showed you how to crash the program and left you with a little mystery to solve. Today we are giving the solution of that and then introducing shellcode usage and remote command execution.
Hi everyone! Last time we finished analyzing the assembly representation of our vulnerable piece of code (have I ever told you it is vulnerable?). This time we are going to introduce some fundaments about exploitation by demonstrating how to crash a program's execution. If that sounds lame, next time we will see how this crash can in fact be useful to control the program's execution, achieving remote code execution!
When you have a parent who cooks—and has you act as sous chef—the kitchen automatically becomes a less intimidating place. In other words, kids who know their way around the kitchen will most likely become adults who cook for themselves, which also means that they'll eat more unprocessed whole foods, save money, and maintain a healthy weight.
After utilizing Spotify's My Year in Music tool, I came to realize that I listened to over 30,000 minutes of music in 2014. Most of that was played while working from my Mac using the desktop version of the service.
The importance of body language is stressed from an early age: watch those around you, and you'll know what they're thinking. While you might be skilled at deciphering the messages of crossed arms, slouched sitting, eye movements, and hand gestures, the key to understanding those around you is a little less obvious.
Welcome back, my greenhorn hackers! Before we attempt to exploit any target, it is wise to do proper reconnaissance. Without doing reconnaissance, you will likely be wasting your time and energy as well as risking your freedom. In previous guides, I have demonstrated multiple ways to perform reconnaissance including passive recon with Netcraft, active recon with Nmap or hping3, recon by exploiting DNS or SNMP, and many others.
This is the first installment in a new series that I am calling "Hacker Hurdles." These are things, methods, techniques that make our job as hackers more challenging and difficult. Don't misunderstand me, these items don't make our task impossible, but rather more challenging and, therefore, more gratifying when we are successful. One of the most important new hurdles for hackers is DEP and ASLR. Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) are designed to pre...
Though many students spend four years of high school learning a foreign language, most of us probably retained very little.

Welcome back, my budding hackers! People often ask me, "Why are you training hackers? Isn't that illegal?" Although I usually give them a short version of this post, there are MANY reasons why YOU should be studying hacking.

Last year, The New York Times wrote that certain restaurants in Manhattan and Brooklyn banned patrons from taking photos of their meals. That means no flash photography, no standing on chairs for a better angle, not even a quick pic for your Instagram followers before the first bite. Little do these restaurants know, this ban can actually make their customers' food taste worse, so to speak.
True story: a friend of mine regularly started a fight with her boyfriend everyday at 4 p.m. Every day. This went on for years until he finally got the bright idea of shoving a granola bar at her the minute she came home from work. Shazam! The fights were a thing of the past.
This week, Google sidestepped their usual "Update Wednesday" strategy by dropping a huge update to their Maps app for both Android and iOS. We're accustomed to seeing new features and bug fixes to their stable of apps on Wednesdays, but today's Maps update was presumably big enough to get its own release day (it's Tuesday, folks).
