Writeup: The SANS HOLIDAY HACK CHALLENGE 2021 - Kringlecon 4 CALLING BIRDS!

Another year, another SANS Holiday Hack Challenge! Here's my writeup for the 2021 edition!

It’s that time of the year again, to reveal my writeup for the Sans Holiday Hack Challenge. This time around Sans named the game “Kringlecon 4 – Calling Birds!”. My last year submission resulted in an “Honorable Mention”. Since I have had major issues with documenting massive writeups using WordPress , I have decided to skip converting my writeup to HTML. Instead, I’ll just link to the PDF. Here…

Writeup: The SANS HOLIDAY HACK CHALLENGE 2018 - Kringlecon

My writeup for the SANS Holiday Hack Challenge 2018! What a GREAT game! #Kringlecon

The most beautiful event of 2018 has ended. Kringlecon is over! I’m a bit sad about it because the game was just so good this year! There were plenty of interesting tasks and objectives. Everything from simple assignments such as breaking out of VI to tearing apart and analysing a malware! Heck, you even had to transpose a piece of music from one key to another! Very varied indeed.

Since I have…

Got slow portscans on CTF's?

Got slow portscans on CTF's? You will not believe how much this post will help you!

Aaaaaargh, my port scan take forever to complete! Heard that one before? You should have, it is a common complaint often heard between CTF rookies. Today we are looking into some ways to mitigate slow scans.

Nmap

When looking at the various complaints, Nmap seem to be the culprit. Gamers bash it for being slow and whatnot. Is it that bad? No, it isn’t. It’s all PEBCAK. It’s all about knowing how…

Trollcave 1.2 - walkthrough

Been busy this weekend creating a walkthrough for Trollcave 1.2! #vulnhub

Trollcave is a vulnerable VM, in the tradition of Vulnhub and infosec wargames in general. You start with a virtual machine which you know nothing about – no usernames, no passwords, just what you can see on the network. In this instance, you’ll see a simple community blogging website with a bunch of users. From this initial point, you enumerate the machine’s running services and general…

Notes on making CTF games

Some time ago I wrote a post named “unofficial guide to creating CTF VMs“. Since then I have been approached by random people, students I mentor and colleagues asking how to make that virtual machine vulnerable. Well, I never intended that post to reveal that. It was simply left as an exercise to the readers. Today I will lift the veil on my process for making vulnerable games. After giving it…

Zico2:1 - walkthrough

Dealing with daylight saving time ... My #Zico wakthrough! #vulnhub

Description from Vulnhub: Zico is trying to build his website but is having some trouble in choosing what CMS to use. After some tries on a few popular ones, he decided to build his own. Was that a good idea? Host discovery As always, I went hunting for the target: msf > db_nmap -sn 192.168.110.0/24 msf > ping6 -I eth1 -c 2 ff02::1 IPv Address IPv4 192.168.110.28 IPv6…

Just finished my Bulldog 1 walkthrough! #Vulnhub

Description from Vulnhub: “Bulldog Industries recently had its website defaced and owned by the malicious German Shepherd Hack Team. Could this mean there are more vulnerabilities to exploit? Why don’t you find out? 🙂 This is a standard Boot-to-Root. Your only goal is to get into the root directory and see the congratulatory message, how you do it is up to you!

SuperMario Host 1.0.1 - walkthrough

Got another walkthrough, this time for SuperMario Host 1.0.1 #vulnhub

Autumn is here, and also a new segment in my Vulnhub series. This time I have had a look at the SuperMario Host game and at the same time re-invented my routines. Enough chit-chat, let’s start! Away we go! Host and Service Discovery My routine for host and service discovery has changed to also cover IPv6. To make my life easier I’ve also begun to use Metasploit. $ sudo msfconsole msf > nmap -sn…

Welcome to another segment in my Vulnhub series! Haven’t had much time to focus on these lately due to work – but I managed to squeeze in some time over the last few weeks to play with the Proteus game. So here it is! Description from Vulnhub: “An IT Company implemented a new malware analysis tool for their employees to scan potentially malicious files. This PoC could be a make or break for the…

DonkeyDocker 1 - Walkthrough

Starting May with a writeup for #DonkeyDocker! Having fun with #Docker. #Vulnhub

This writeup covers the Vulnhub CTF game DonkeyDocker 1 (2017), which might be the most interesting game I have played this year. In this game players are to play with Docker – a task that lies close to my heart since I love this technology. Although I am bit rusty on it ever since I quit programming and server management. Anyhow, this game is rated hard/intermediate by the creator. There’s no…

Hackfest 2016 Quaoar - walkthrough

Dazing in the shade. Here's a walkthrough for #Hackfest 2016 #Quaoar!

Another week, another CTF under my belt. Been doing a lot of CTF games the past months. This time I took some time off my schedule to play with the hackfest2016: Quaoar game. The difficulty level on this one is pretty low, which suited me fine this time around. It’s nice to have something to keep oneself occupied that doesn’t require much braining. Anyway, lets cut to the chase! Description From…

Ew_Skuzzy 1 - walkthrough

Been productive! Here's walkthrough for Ew_Skuzzy 1! #vulnhub

Today I am sharing my work log for the “Ew_Skuzzy: 1” CTF game. This game was released only recently, on the 17th of March 2017. As of time of writing, there haven’t been much information released about it. That adds another dimension to solving it and suits me fine. As always I have based my work on Parrot instead of Kali Linux. These distribution appears more or less the same and you should…
