Exploit Development: How to Manipulate Code Execution with the Instruction Pointer

The one thing that separates a script kiddy from a legitimate hacker or security professional is the ability to program. Script kiddies use other people's tools, while hackers and security pros write their own tools. To that end, we're going to see how a stack overflow vulnerability allows us to flood a variable with enough input to overwrite the instruction pointer with our own commands.

How To: Find Anyone's Private Phone Number Using Facebook

Facebook really wants your phone number, nagging you for one as soon as you join. This isn't all bad since it can help secure your account with two-factor authentication. On the flipside, this makes it easy to reveal the private phone numbers of virtually anyone on Facebook, including celebrities and politicians. We're going to look at how a hacker would do this and how to protect yourself.

How To: Security-Oriented C Tutorial 0x21 - Linked Lists

Welcome to the final tutorial of the series on standard C. This article will cover the linked list abstract data type (ADT). There will be a lot of abstraction to try to deliver the understanding in the most basic way for easiest interpretation of what they are and how they work, then we will get into the guts of it and learn the technical code underneath. For those who have yet to grasp the concept of pointers, it's advisable that you do that first before approaching this. Having learned thi...

How to Meterpreter: Obtaining User Credentials with PowerShell

In this article I will show you how to obtain victim's credentials without cracking any hashes. There are a couple of ways to perform this task (for example dumping the SAM file and cracking the NTLM hashes), but here I will explain how to do it using PowerShell and a bit of social engineering. We are going to create a fake login popup.

How-to Ruby : Simple SSH Bruteforcer

Hello fellow training hackers. I do not know if many of you are familiar with ruby, but since it is a useful scripting language, that hasn't been covered too much here on Null Byte, I thought why not do some How-tos about it now and then.

How To: Stream Spotify Music to Chromecast from Your Android or iPhone

One of the highest rated posts on Spotify's own community forum is titled "Add support for Google Chromecast," a clear indicator of not only how much this feature is desired, but also of Spotify's lack of care for it. Remaining consistent with statements made in the past, Spotify is firm in their decision to not pursue Chromecast support at this time—or maybe ever—thanks to a deal with Sonos and Spotify Connect.

How To: Find the Location of Any IP with PyGeo IP Locator(GUI for GeoIP/Pygeoip)

Based on OTW's encouragement in his post on "How to Find the Exact Location of Any IP Address", I decided to make a gui(graphical user interface) which would hopefully make the process easier. However, because turning a python script into a standalone executable is a right pain in the nether-regions, particularly for linux, I haven't yet completed this step(I will soon and update this). I did however, make an apk for android(you use a .apk file to install an app on your android device), which...

How To: Use Your Phone's Camera to Split Bills More Easily with Friends

When going out to eat with friends, it's inevitable that one person takes charge at the end of the meal to split the bill. They whip out a pen and begin asking everyone what they ordered, carefully dividing, adding, and subtracting on the back of the receipt for everyone to use. Unfortunately, that never seems to work as intended. One person will end up paying a little more, while another will pay less.
