Writeup: Timbershade - TRAFFIC ANALYSIS EXERCISE

3 minute read Published:

I had already solved one exercise from @malware_traffic's website about network traffic related to malware infections. I have been slow to pick a new exercise from the very long list but I chose Timbershade and it was a lot of fun! Short one, but learned a lot once again.
Malware Traffic Analysis @malware_traffic blog has a lot of knowledge so I highly recommend to bookmark it somewhere. The real treasure is of course the amazing exercises page. Depending on the exercise, you get a pcap and other files. The pcap file is a traffic capture which we can analyse in Wireshark and find out where things went wrong! Being able to effectively analyse traffic is a very important skill for the security of any organisation.

i18 Challenge - Part 1

5 minute read Published:

I was given the link to this CTF that ran back in 2015, and I thought I would take the opportunity to start writing about my thought process using these challenges. If you want to try for yourself, the link is at the beginning of the post.
The i18 has 13 challenges that you can find at this address. This CTF is in Norwegian, but has a very small amount of text so google translate is more than enough, but I will translate the text and clues to english here. This is the first part of my writeup where I will do the first 4 challenges. It is very possible that I will make mistakes or take longer path to the flag, so if you have any recommandation or correction, feel free to contact me by email or twitter.
