Hacking Thick Clients – Authorization Bypass

Hello Readers, This post will be focused on setting up a vulnerable thick client application and finding vulnerabilities. The blog post is an unofficial part of the on going series of post by NetSPI. NetSPI has released a vulnerable thick client app called BetaFast which has two versions - BetaBank and BetaFast based on 2-tier and 3-tier architecture respectively. The app is coded by Austin Altmann  and he is writing the walk-through series. Note: At the time of writing this blog, the walk-through/write-up for authorization bypass vulnerability was yet to be published by NetSPI and therefore I decided to create this blog post. All the credit for developing and maintaining this app goes to Austin and NetSPI team. You can find some of the cool write-ups here . Let's start. Setting up Betafast - 1. Download the files from github -  https://github.com/NetSPI/BetaFast  . 2. Extract and open the...

Review of Pentester Academy - Attacking and Defending Active Directory Lab

Few months ago I didn't know what Active Directory is, and why should I care about it and never heard about ACL abuse and all. Although I had attended a BPAD (Breaking and Pwning Active Directory) training which was provided by Nullcon but I was not confident enough to go for this course exam, since my day-today activity involves VAPT stuffs related to Web/Network/Mobile and sometimes basic malware analysis (very basic one :p).  I started doing offshore lab and took help from some friends in understanding few Active Directory concepts. I did many silly mistakes during the lab and learned a lot. Meanwhile I registered for Active Directory Lab Course and got it in a discounted offer for first 50 students of about 11k INR  ( 1 mont lab access) :). Before wasting time any further let's dive into the review.
