Today I came across a blog post titled An Easy Problem Made Hard: Rust & Binary Trees. It presented an interesting challenge to me, because it explained how in Rust this problem became harder due to its model and I wanted to understand if it can...
Intro It's been a while since part 3, though not for lack of progress on the analysis. The work over the last month or so has largely consisted of persistent analysis of the binary. There's not that much to share in terms of exciting updates,...
Intro In the previous post I introduced what we're doing so if you haven't read that, do that first or this won't make much sense. At the end of the previous post we concluded that we'll need to reverse engineer the driver to understand the...
Intro Time for part 3! Previously we started reverse engineering the driver using Ghidra. While this works, it sometimes runs into problems when it's hard to understand how functions are called. To a large extent this is driven by the application...
Intro I've got a Kensington fingerprint scanner that I used to use on Windows, but since I've switched to Linux, it's just been sitting on my desk, largely unused. Unfortunately, there really aren't any fingerprint scanners for Linux that plug...
I am starting to toy around with Kubernetes in my homelab. One of the services I recently set up outside of Kubernetes was Authentik which has allowed me to configure authentication centrally. It's pretty minimal at this point, but one thing I've...
I run quite a few services in my homelab and they have been fronted by nginx basically since the beginning. Recently, I wanted to modernise things a bit and found myself migrating to caddy which meant replacing all the use cases I had developed...
Note This is a repost on my personal blog of the tutorial I published on the Proxmox forums. Go read the post and discussion there, this is merely as a backup. If you want to encrypt your data, the best way is usually to start at the lowest layer...
I have not blogged in a looooong time (almost 10 years!). For the most part, this was due to personal reasons, but also because I didn't have many side projects that were worth talking about. In fact, for quite some time this blog has been down,...
So the Secuinside CTF 2014 just finished. Overall we did okay, but could have rocked this one more. Unfortunately, there was a lot of reversing stuff, not my strong suit. However, the first challenge I attempted was one of those that really...
