SANS SEC575 Mentor Class

Hi everyone,

Great news! I will be mentoring SANS 575: Mobile Device Security and Ethical Hacking in Luxembourg on Thursday evenings 18:00-20:00, starting from January 15, 2015.

Mentor classes are special, 10 week-format SANS classroom sessions that give the students time to absorb and master the same material with the guidance of a trained security professional.

Students receive all the same course materials used at SANS conferences and study at a more leisurely pace, so students will have:
  • Hardcopy set of SANS course books
  • Mentor Program study materials
  • Weekly Mentor led sessions
Prior to the weekly Mentor-led classroom sessions, students study SANS course material at their own pace. Each week, students meet with other professionals in their hometown area and the SANS mentor, who leads topical discussions pointing out the most salient features of the weekly material studied, provides hands-on demonstrations, and answer questions. The Mentor's goal is to help student's grasp the more difficult material, master the exercises, demonstrate the tools and prepare for GIAC certification.

On SANS SEC575, we will learn about mobile device infrastructures, policies and management, we will see the security models of the different platforms, like the data storage and file system architecture. We will also see how to unlock, root and jailbreak mobile devices in order to prepare them for data extraction and further testing. In the second half of the course, we will learn how to perform static and dynamic mobile application analysis, the usage of automated application analysis tools and how to manipulate application behavior. Last but not least, we will see how to perform mobile penetration testing that includes fingerprinting mobile devices, wireless network probing and scanning, attacking wireless infrastructures, using network manipulation attacks and attacks against mobile applications and back-end applications.

Evil Limiter: Taking Control Of Your Network Bandwidth







Ever wanted to block someone from the network or limit their bandwidth without having the network admin privileges? Well Evil Limiter has got you covered then.


An amazing tool to help you control your network without having access to the admin panel.

Today I'm gonna show you how to use this interesting tool to take control of your network.


Requirements:

1. A PC or Laptop with Linux OS.
2. A Network Adapter.
3. Access to the Network you want to control.
4. sudo or root access on your Linux OS.

First of all we will download the tool from its github repository:

https://github.com/bitbrute/evillimiter

You can download and extract the zip file from the link above or you can clone evillimiter repository using git like this:


git clone https://github.com/bitbrute/evillimiter 


Now lets install the downloaded tool on our machine

Step 1: Move inside the downloaded github repository

cd evillimiter


Step 2: To install type


sudo python3 setup.py install


wait for the installation to finish (May take some time)


Step 3: To run type


sudo evilimiter


Voila! That's it, you got it up and running on your machine


Now how do you control your network with it, its very easy.

It should detect your network automatically but yeah you can set it up manually as well using the command line argument -i.

After you have selected the right interface to control, you need to scan your network for live hosts. To perform the scan type


scan


you can pass an optional flag to the scan command which is range which will help you to specify the range of ip addresses you want to scan like this


scan --range 192.168.1.1-192.168.1.100





The above command will scan a total of 100 hosts from 192.168.1.1 to 192.168.1.100


Now after you have scanned your network next thing is to list the hosts that have been discovered during the scan for that you type the hosts command like this


hosts





Now you know the hosts on your network and now you should know which host you wanna block or limit based on the mac address of the host. Remember the host id of the host that you want to block or limit bandwidth of and lets do the magic.

to block a host from using the internet we simply specify the block command followed by the host id of the host that we want to block like this

block 1





if instead of blocking the host we just want to limit his internet bandwidth we can do just that by using the limit command followed by the host id and then the bandwidth that we want to allocate to that particular host like this


limit 1 100kbits





Wohooo! yeah its that easy and yes you can do all this without having the network admin role.

Now if you want to show mercy on that poor guy (blocked host), you can set him free by using the free command followed by the host id like this:

free 1





Well isn't administrating your network bandwidth so easy now.

Hope you enjoyed this tutorial.:)
