1)About & Why
With hackers striving to become the Picasso of the IT world, we are seeing more creative and abstract attack techniques being developed to bypass defences.
As a defender, it is becoming increasingly important that you understand the deep and dirty inner workings of how these attacks compromise your systems and establish a connection with the attacker in order to effectively protect your environment.
From the offensive point of view, organisations are becoming increasingly paranoid about suffering security breaches, and rightly so. This means that they are investing heavily in security and implementing more advanced prevention mechanisms. As an attacker or penetration tester, we are facing the reality that many pre-packaged attacks are being detected, which means that we need to become creative to stay ahead of the defensive controls.
So lets increase your exploitation success rate! Wouldn't it be great if you could write your own shellcode to bypass security controls such as firewalls, authenticated proxies, intrusion prevention systems, and threat detection systems to increase your exploitation success rate? Well now you can!
"The Shellcode Lab" training at Black Hat USA teaches you the ins and outs of each of the major attack techniques. Not only that, every student learns how to actually develop their own variety of custom shellcode from scratch for Linux, Windows, and Mac OSX.
The course is structured in a way that every student succeeds! 95% of students have never touched shellcode before, but by the end of Day 1, every single student has written from scratch "Mac OSX 64-bit Port Bind Shellcode" to gain a remote shell on the victim host.
The development of the shellcode is presented using easy to learn techniques. Starting off with an introduction to different shellcoding techniques on each platform, an introduction to basic memory management and assembly, followed by creating simple shellcode to write to stdout and call functions.
This gives students a base understanding and practical experience to develop simple shellcode. The complexity is then increased to more useful shellcode such as command execution, dynamic Windows shellcode, setting up backdoor listeners using sockets, shellcode networking to remotely gain a command shell, and egg hunter shellcode to search through memory for our payload. All of this is done whilst holding your hand so that you don't miss a beat. Students will also learn about staged-loading shellcode to bypass security controls, and kernel level shellcode to perform privilege escalation.
Students are taught how to encode their shellcode using the Metasploit Exploit Framework (MSF), and insert it into exploits that will be used to show that their shellcode was successfully executed. They will learn how to use MSF to generate shellcode for a variety of platforms, as well as create a Metasploit Payload Module so that your shellcode is available to all Metasploit exploits.
For the Tech Segment, we are going to step through one of labs from our Black Hat course "The Shellcode lab" where we develop shellcode from scratch to spawn a command shell on Linux.
The flow of the course starts at:
- Teaching basic assembly and shellcoding concepts including writing small and null-free shellcode, - Followed by 32-bit shellcoding on Linux to ease the students in, - This leads into more advanced 64-bit Mac OS X and Windows shellcoding. - The course then teaches how to integrate your shellcode into public exploits, - Students then create a Metasploit Payload Module that they add into Metasploit. - We then use the shellcode that students have developed in the course to actually exploit vulnerabilities to compromise systems.
For the Tech Segment, we will first step through:
- the structure of the assembly file, - including the code segment, - what registers we need to use, and - what functions we need to call.
This will then be followed by coding up some shellcode in assembly, including showing a few techniques on how to achieve things like clearing registers, locating strings, and calling syscalls.
We will then demonstrate a nice and easy way to compile the assembly, extract the shellcode, and run a test program to test that our shellcode functions as we expect.
We can do a quick demo of how to make shellcode small so that it fits into more exploits so that you can compromise more systems.

Hopefully I can clean this up and make a proper article of it, in response to this I wrote this:
So, lets ask the question what value does the annual pen test derive? We’ve covered this extensively on the show.
Could this money spent on a penetration test be put to a different and better use? - Sure, you could spend money on a lot of things, like training, more security staff, products and more. Is that better? If you shifted your pen test budget and spent money on different things who do you know its working? How do you know you spent the money on the right things? Pen testing helps you focus your budget on the right areas.
Penetration tests attempt to answer the question, “Can my controls be breached?”
If this is the only question your pen test is answering then you got the wrong pen test. Pen tests should answer questions like:
- How could I be breached? - How much damage to my business could a breach of that kind do? - Where am I most likely to be breached given my current defensive posture? - What can an attacker do once I’ve been breached? - How long will it take me to detect the breach? - How well do the people in my organization react to a breach, or someone trying to breach security?
Assumptions they claim people make:
- My controls are not already breached - part of a penetration test now includes breach/malware discovery
- Breaches only happen due to missing controls and pen tests discover that - I think this is a correct assumption for a well-defined pen test
- Pen test test all routes into the network - More importantly is to test the routes inside the network and out of the network in addition to the routes in.
“Mandiant assesses hundreds of organizations around the world every month, and we find 95% of them “breached” “ - hum, thats because people call you when they’ve been breached or think they have been breached.
“The attackers employed advanced means to bypass these controls and got in without being noticed.” - Thats the point of a pen test, except the difference is you get to find out how without incurring damages.
“ If I were to use an analogy, getting breached is like falling ill. “ - Getting breached is not like falling ill, its more like someone broke into your house or car or office. Or more like someone picked your pocket. There are some major differences:
- Illness does not use the Internet to find out information about its victims, infections are random by organisms that do not have brains and reasoning like humans
- Some illnesses are a result of genetics, which doesn’t come into play when you build an organization. You get to choose which defenses you put in place and control your weaknesses. As a human, I can’t control the fact that I am genetically predisposed to high cholesterol
- Despite the fact you get sick, you still likely go to the doctor every year for a check up. And at Jack’s age, that entails a penetration test…
- In a network, there isn’t such a thing as treatment, there is just removal. You wouldn’t put your network on antibiotics and fight an infection. Infections happen, and they all need to be removed, there is no middle ground in terms of treatment.
