Night Owl DVR Reset

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.

How to Check Your Linux Version: os-release, uname and lsb_release

Ever wonder what Linux version is running on your machine? I commonly connect to friends’ machines, or to one of my servers, and I have no clue what’s on it. This can make a huge difference, as some distributions use apt, some use dnf or yum, and some use something else entirely. Luckily, there are a few commands that answer this in a second.

In this article, we’re going to cover /etc/os-release, uname, lsb_release, and hostnamectl.

In my previous article about Hack The Box, we made an account on the site. In this article, we’re going to be tackling the Bitlab box, which you can find the page for here

Undocumented APIs

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.

OverTheWire Bandit Part 2

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.

OverTheWire Bandit Part 1

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.

Hack The Box Intro

Hack The Box is a website that gives people a great place to test their penetration testing (hacking) skills. They have a selection of different machines available that are vulnerable to different types of attacks. This site uses the capture the flag scoring mechanism, where you hack machines, get a “flag” from them, and submit it to their site for points.

In this article, I’ll cover how to make an account on HTB.
