About The Project This past weekend was the final Shmoocon and the final Hack Fortress….for now. This blog post is a writeup on developing an 802.11 challenge for Hack Fortress while considering the congested 802.11 environment that is the Shmoocon conference. By leveraging the Linux kernel’s hwsim and hostapd, competitors were able to capture beacon frames, parse SSIDs, and ultimately solve a 802.11 challenge that never actually broadcasted a beacon frame over RF!| Arch Cloud Labs
About The Project Just like every year before, 2025 is the year of the Linux desktop. With Kubernetes solidifying itself as the de facto platform for container deployment, and Valve’s Arch Linux based Steam Deck, Linux continues its dominance in corporate environments, and our personal lives. I believe an investment in learning the internals of Linux will pay dividends for career progression, and it’s also a lot of fun to use.| Arch Cloud Labs
Parallelizing Pacman Downloads I usually start off blog posts with an “about the project”, but this is a very short one so lets just get right into it! You should modify your pacman.conf file to enable parallelization of downloads. It’ll speed up installation of packages that have several dependencies. For all those distro hoppers out there, this should speed up your install times. By default the ParallelDownloads option is set to only 5, but can be configured up any positive integer.| Arch Cloud Labs
About The Project Following up from the most recent Arch Cloud Labs blog post on researching and choosing hardware for OpenWrt, this blog post will quickly cover how to build an OpenWrt image for a physical device. If you’re interested in building and testing an image in a Virtual machine or a container, look at the “Developer Guide” for more details. Now, onto building OpenWrt! Containerizing The Quick Build Guide Environment The OpenWrt Developer “Quick Build” guide outlines the n...| Arch Cloud Labs
About The Project Here at Arch Cloud Labs, we love Arch Linux due to the ability to customize, debug, and otherwise modify every aspect of the system. This level of visibility into an Operating System allows the end user the ability to (in theory) fix any issue they come across with sufficient time and resources. Troubleshooting issues as they arise over time also makes you a better Developer/Sys Admin/hacker/etc… as well.| Projects on Arch Cloud Labs
About The Project The best blogging platforms are frictionless, and give the author control on how to create and share content. Arch Cloud Labs hosting has evolved over the years from a simple Digital Ocean droplet to a containerized deployment with CI/CD integration with a Cloud provider. This article briefly covers that journey and highlights the ease of integration and low cost of operating a modern blog with Digital Ocean’s App Platform.| Projects on Arch Cloud Labs
About the Project Five years ago, on September 22 2019, I published my first blog post titled “New Homelab”. This began a journey in documenting side-projects done on nights and weekends to build skills in Reverse Engineering, Malware Analysis, and other InfoSec disciplines. While originally created to build a resume of projects for future employers, it evolved into a platform that afforded me opportunities to teach workshops at leading security conferences, land a new job, compete in a i...| Arch Cloud Labs
About The Project Hack Fortress (HF) is a combination of a first person shooter (Team Fortress 2), and a jeopardy style CTF. Teams of ten are assembled with six gamers and four hackers in a single-elimination bracket. Hackers solve challenges and unlock points to buy in-game items for gamers. Each round is thirty minutes long except for the finals which run for forty-five minutes I’ve previously blogged about Hack Fortress(12) challenges, but this blog post is going to cover how each round ...| Arch Cloud Labs
About The Project I recently bought an discontinued TrendNet Router to become more proficient at reverse engineering embedded systems. Each year at DEF CON, the IoT Village,and Embedded Village have CTFs/hands-on workshops, and I’m hoping to get my skills up to par to go and take a crack at one of them next year. TrendNet home router model “TEW-731BRv2” has a known vulnerability identified by CVE-2015-1187) that leads to remote code execution.| Arch Cloud Labs
About The Project Continuing from the last blog post that discussed malicious Linux Cryptocurrency miners, I have discovered new activity that blends two of my previous Cryptocurrency mining malware (aka Cryptojacking) blog posts. By taking a deeper look at infrastructure, and code artifacts some interesting parallels can be drawn between the same actor(s) that Trend Micro refers to as Skidmap and another Golang Cryptojacking malware variant that Palo Alto has just recently deemed “Watchdog...| Arch Cloud Labs
About the Project Since July of 2020, I have been running a “honeypot” of sorts made by anthok to capture all requests coming in on specific ports. By listening on ports commonly used by databases such as Elasticsearch or Redis, we’ve been able to observe a lot of bot behavior. Most of the requests resulted in trying to gain an initial foothold onto the environment to run a bash script to bring down their stage-1 malware.| Arch Cloud Labs
About The Project Given the recent news of the Meow attacks, I was curious about obtaining malware data related to Elasticsearch attacks. I’m a huge fan of Elasticsearch and use it heavily in my side-projects. I’m aware of the dangers of exposing a fresh database install on the open internet. So I simply set up a netcat listener and redirected the output to a file. I was pleasantly surprised at how successful this was.| Arch Cloud Labs
