I recently had a friend lose access to his Night Owl WNVR201 device. He said he lost his password, and I said I'd see what I could do. Through a long day of reverse engineering it, I found out how to reset the password on the device.
Ever wonder what Linux version is running on your machine? I commonly connect to friend's machines, or to one of my servers and I have no clue. This can make a huge difference, as some distributions use
apt, and some use
yum. There are two super helpful commands to accomplish figuring this out.
Because I always love to push the envelope, and love learning how different services work in the background, I find myself running into undocumented APIs fairly regularly. Through writing many random bots, I've come up with a pretty nice workflow for handling, and documenting these APIs.
This article is going to cover how I typically go about the endeavor of documenting unknown APIs.
I find myself fairly regularly hearing about new features in the Linux kernel (the core of Linux operating systems), getting excited, and checking to see if my distribution's repository of packages has the latest kernel built. Unfortunately, Ubuntu's repositories don't have the most recent versions of the kernel available for some time.
Fortunately, the Linux kernel is open source, so we can freely download the kernel's source code, compile it, and install it.
This article details the steps necessary on a fresh install of Ubuntu 19.10 (Eoan Ermine).
In my last post, I walked us through connecting to OverTheWire's Bandit server, and completing level 0 and level 1. Following along with the previous article is a prerequisite to following this article, as you'll need to get the password from the file in level 1 first.
You can view my last post about this by following this link.
What is OverTheWire?
OverTheWire is a website with two games. One is "Wargames", which is a level based game, the other game is "Warzone", which is more of a free-for-all hacking game.
In this series of articles, I'm going to give a walkthrough of how to complete the "Bandit" series of levels on their website.
What's all the frenzy around "neural networks"?
I keep seeing news about something awesome that a computer has been "trained" to do with "deep learning". These news spiels refer to something called "Q Learning", "Deep Learning Neural Networks", or "Hierarchical Learning".
Although these are huge terms, it's a pretty simple idea as to how they work. In this article, we cover some of the basics of this genre of algorithm.
