Thanks.

Hi,

after 5 years I decide to close this blog. The same I will do with my LinkedIn
and Twitter account so I will not be available any more.

I would like to thank you all for watching and supporting me during those years. :)

"Have fun & good luck."

Thanks.

Cheers

FristiLeaks: 1.3 CTF Writeup

During last day I had a pleasure to play FristiLEaks CTF prepared by Ar0xA. Thanks! ;)
It was a good idea to choose this one as well as a lot of fun when I was wondering how to get root.

Below you will find a solution how to get the flag (and to "love Fristi"! ;))
(For those who want to read other writeups for Fristi, you can find them here.)

Here we go...

CrackMe by Rapture - solved

Hi,

this time we will analyze and patch another small and simple .NET crackme.
This time we will check "FishMe #1 by Rapture". You can find it at crackmes.de.

Like before we need HxD and .NET Reflector (but you can use your favourite tools to do it as well).

Let's get to work!

CrackMe by Rayko - solved

Below you will find one simple solution for crackme found in ".Net" category: CrackMe By Rayko.

Another DoS in MS Publisher 2010

BrokenWebapps - CTF writeup

When I was looking for a new CTF, I found interesting website with multiple CTFs ISO and VM images, prepared (vulnerable) to hack. I decided to try OWASP Project called BrokenWebapps (VM I’ve tried was OWASP_Broken_Web_Apps_VM_1.2).

I prepared the VM and started another one (this time with Kali2.0 – both on VirtualBox). As far as I know, we can treat this VM as a big WWW server, hosting multiple webpages.
