Get your hands dirty playing with RFID/NFC

This is a guest blog post by Nahuel Grisolia.

The first time I’ve heard about RFID was at high school, back in 2002, when I was studying Electronics. Back in that time, this technology was like some sort of black magic to me. A few years later in 2011, our government in Argentina decided to implement a “new technology” called NFC, designed as the new and only way of payment for the use of public transport. So, I decided to understand it better, play with it, and try some hacks I heard from the cool people of the CCC.

White Paper on Incident Analysis and Forensics in Docker Environments

In this article, we describe the impact of the increased use of Docker in corporate environments on forensic investigations and incident analysis. Even though Docker is being used more and more (Portworx, Inc., 2017), the implications of the changed runtime environment for forensic processes and tools have barely been considered. We describe the technological basics of Docker and, based on them, outline the differences that occur with respect to digital evidence and previously used methods for evidence acquisition. Specifically, we look at digital evidence within a Docker container which are lost or need to be acquired in different ways compared to a classical virtual machine, and what new traces and opportunities arise from Docker itself.

AndroTickler: Tickling Vulnerabilities out of Android Apps

If you attack someone, they will defend themselves, but if you tickle them, they will eventually crack open. This surprisingly applies to Android apps as well! Therefore, I created AndroTickler, not to test apps against certain attacks or examine them for specific vulnerabilities, which developers would learn to avoid. However, it helps pentesters to analyze and test apps in their own style, but in a faster, easier and more flexible way. AndroTickler is a Swiss-Army-Knife pentesting tool for Android apps. It provides information gathering, static and dynamic analysis features, and also automates actions that pentesters frequently do and highly need during their pentests. In addition, it makes use of the powerful Frida to hook to the app and manipulate it in real-time.

TelcoSecDay 2018 – CFP and First talks

We have a short update from the TelcoSecDay 2018 Agenda. But before that, a short reminder. The CFP for TelcoSecDay 2018 is still open. If you are into telco research, and if you have something interesting to talk, please make a submission here. The deadline is 17th February 2018.

Here are the first two confirmed speakers who are going to talk about the below mentioned topics:

Title: Data Security for 4G Interconnection and 5G Interconnection Risk Areas

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.

Blackhoodie at TROOPERS18

We are thrilled to announce the Blackhoodie event at Troopers 2018 on March 12th and 13th in Heidelberg. This time it is going to be a 2 day workshop with various interesting topics related to reverse engineering. We will make sure that you get some hands on experience with reversing and more.

As always, one of the main motivation for Blackhoodie is bringing more women into reversing.
So we would like to see more women apply to the training slots. However, we are open to everyone who would like to apply. 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! Please apply before “February 20th” and we will contact you regarding next steps.

Virtualized Training Environment with Ansible

As Kai and I will be holding a TROOPERS workshop on automation with ansible, we needed a setup for the attendees to use ansible against virtual machines we set up with the necessary environment. The idea was, that every attendee has their own VMs to run ansible against, ideally including one to run ansible from, as we want to avoid setup or version incompatibilities if they set up their own ansible environment on their laptop.  Also they should only be able to talk to their own machines, thus avoiding conflicts because of accidental usage of wrong IPs or host names but also simplify the setup for the users.

White Paper on Multi-Factor Authentication in Microsoft Windows Environments

A new ERNW whitepaper was just published. I wrote this whitepaper in the course of my bachelor thesis and it examines multi-factor authentication in Microsoft Windows environments:

Credential theft and the subsequent reuse of stolen credentials are a significant problem in today’s information security. To counter the associated risks, a planned approach is required as part of a comprehensive security architecture program. This includes the implementation of multi-factor authentication as an important building block. This whitepaper covers the relevant steps of implementing a multi-factor authentication system in an enterprise environment and closes with a security evaluation.

#TR18 Active Directory Security Track

A happy new year to everybody!

At Troopers18 there will be a new special track on Microsoft Active Directory and its security aspects, similar to the SAP security track which we established some years ago. The AD security track will feature, amongst others, the following talks.

Sean Metcalf: Active Directory Security. The Journey

Abstract: This talk is a journey into the challenges most organizations encounter while trying to secure their ‘castle’. The attacker has to be right only once, right? Not exactly. We will walk through effective security strategies that will stymie and frustrate attackers and better protect the Active Directory environment.

Yet another edition of BlackHoodie – #BlackHoodie17

I am amazed by how this years BlackHoodie unraveled. Three days that included a pre-conference of lightening talks and two parallel tracks with a total of 64 enthusiastic members. The very spirit of BlackHoodie is nothing other than the quest to gain deep knowledge. Reverse engineering is one of the hardest fields in security. It touches on all fields of computing, starting from assembly, programming, file formats, operating systems, networks and what not. This makes it hard but an extremely fulfilling experience to spend time learning it. For me, the very idea of staring at a binary till you understand what it does is a magical feeling.
