Blackhoodie@Troopers 2020

Once again, we are super excited to announce that Blackhoodie is happening at Troopers 2020. This is the 3rd time that Blackhoodie is joining with Troopers. As always, one of the main motivation for Blackhoodie is bringing more women into reversing and other core security topics. So we would like to see more women apply to the training slots. However, if you are not a woman and still feel really excited about Blackhoodie, you are welcome to apply. The registration is open now.  Please hurry up and make your registration now. We will close the registration once the seats are filled up with enough quality submissions. We do have a very limited number of seats at this training site. So we apologize in advance if we can’t accommodate everyone, even though we wish we could!

How to register?

Blackhoodie is a free event. In order to register, go to this link and fill in your details with a brief motivation of why you would like to join Blackhoodie. We will get back to you with the selection outcome as soon as the registration is closed. Current deadline for registration is Feb 12th 2020.

REGISTER HERE.

16th – 17th March 2020 – Trainings

Training 1: How to (mis)use TLS? by Caroline 
Description: 
Let’s understand how TLS works and demystify some famous flaws in TLS:
what went wrong ? How could we exploit it ? How was is fixed ? 
To answer this questions, the idea is to get our hands on networking, 
man-in-the-middle, rogue certificates crafting, heartbleed exploitation.
Material: have a kali linux virtual machine installed. 
If you don’t know how to do that, I can provide an installation guide.
Training 2: Untangling C++: Reversing and Auditing C++ Binaries by Gal Zaban
Description:
This training is an advanced class for security researchers who want to 
expand their horizons and skills in reversing modern C++ binaries. 
C++ Binaries are full of mysteries, they have objects, inheritance, 
templates, vtables and many more and reverse engineering them is a task on 
its own. The training will explain advanced C++ reverse engineering topics 
including techniques and tools for dealing with research of C++ Binaries.
We will start with the identification of basic C++ patterns including 
identifying statics, globals, arrays, etc. Than we will continue with objects
and inheritance in a binary and how to represent all of those in IDA, 
afterward, we will study work methods and design patterns in C++.
Finally, we will practice, fight and untangle deep and modern C++ programs 
using both static and dynamic analysis.
Class outline:
 - C++ Reverse Engineering Intro.
 - Globals, Statics and Arrays
 - Objects + Objects Creation.
 - Inheritance.
 - Multiple Inheritance.
 - Understanding relationship between objects.
 - Virtual tables and virtual calls.
 - Templates.
 - Important Design Patterns.
 - IDA Pro- concepts and working methods for reverse engineering C++.
 - Representation of C++ objects in IDA.
 - Tips for creating setup and environment for C++ binaries.
 - Existing tools for C++.
 - Deep understanding of a C++ Binary's Logic.
 - Conclusions and wrap-up.
 - Suggestions for future tasks and resources to keep learning and improving C++ RE skills.
Training 3: Tactics, Techniques and Procedures for Attacking Active Directory 
by Kelly Villanueva
More details will be updated.

Diversity, Community, Blackhoodie

Gender equality in the Infosec world as a topic of discussion comes with a lot of heated arguments and differences in opinion.
So let me start with some disclaimers on the target audience for this post. If you are in the category who believes everything about gender is perfect in the infosec world, this post is not for you. If you are in the category who believes gender and bringing diversity is not your area of interest, then this post is not for you either. There are so many interesting problems that the world offers you. Climate change, poverty, diseases, unemployment, addiction, science problems and what not. Everybody has the freedom to choose their area of interest and contribute towards it. If you are in the category who thinks gender equality in infosec needs some attention and would like to explore more on the topic without prejudices, then this post may  be interesting to you.

Hacking 101 to mobile data

Here is a short blog post that explains how you can make your own Man-in-the-Middle (MitM) setup for sniffing the traffic between a SIM card and the backend server. This is NOT a new research but I hope this will help anyone who doesn’t have a telco background to get started to play with mobile data sniffing and fake base stations. This is applicable to many scenarios today as we have so many IoT devices with SIM cards in it that connects to the backend.
In this particular case, I am explaining the simplest scenario where the SIM card is working with 2G and GPRS. You can probably expect me with more articles with 3G, 4G MitM in future. But lets stick to 2G and GPRS for now.
