Vikram Salunke: Pentesting and Exploiting Highly Secured Enterprise Networks

Presented By: Vikram Salunke

Pentesting and Exploiting Highly Secured Enterprise Networks is an action-packed hands-on class giving attendees a chance to perform real-world exploitation on enterprise network scenarios accompanied with practical lab exercises in a CTF style format. The course goes far beyond simple exploitation of low-hanging fruit and shows pentesters how to perform the abilities of an advanced attacker to find flaws in secured networks and calculate the business risk associated with these flaws.

This training is intended for senior/experienced pentesters. Just running a vulnerability scanner and submitting that as your report provides no real benefit to a company. The training goes far beyond your traditional pentesting courses. Real-world Enterprise Networks are much more complex in nature, needing your special attention to choose the techniques and tools that you use in order to infiltrate. A senior penetration tester must succeed when others fail. A senior pentester doesn’t give up when a particular exploit is not working, he tries to analyse the exploit and make some modifications that are necessary. He should think outside of the box and come up with solutions to complex problems. He must have knowledge of all domains and his skills should range from network attacks, web attacks and scripting to system exploitation.

This training is a result of years of pentesting experience, compromising highly secured networks, combined into one practical and hands-on class. This course provides in-depth knowledge of the most powerful attack vectors and provides labs to perform these attacks in numerous hands-on scenarios.

The training has a module on python scripting. Automation of tools is essential due to time constraints so it also helps to automate the testing of systems, services, and applications. Multiple python Modules, libraries and debugging tools have already been written to help simplify and automate fuzzing and research. In order to reach the next level in penetration testing, one must embrace the idea of adding programming into their penetration testing toolkit. Once obtaining this power, tools can be written and shared, allowing you to build up an arsenal for reconnaissance, scanning, fuzzing, and exploitation.

Metasploit and other 3rd party tools are easily detectable by modern security solutions. They have fingerprinted quite well and so it is not possible to have an emulated modern powerful adversary using these tools, so there is need for custom code. When we are using custom code, it is target specific and there is no mass deployment so antivirus vendors don’t have a signature for it. Building custom scripts will also help in bypassing firewall, IDS/IPS and to evade AV.  Custom script will help in post exploitation such as list patches, list users, list AD accounts in active directory, pull passwords with mimikatz and bypass UAC etc. When you are attacking, it is useful to load code into remote process and have it execute within that process’ context. So for this we will use DLL injection. We will write DLL injector using Python and this will help us to evade firewalls.

As a pentester you need to be familiar with how to edit, modify and execute shellcodes and be able to understand how exploit works. There are few scripts on internet which cause harm to your system, so you need to how the scripts work. Metasploit’s XOR, shikata_ga_gai encoders are quite well detectable by AntiVirus so we will write our own custom encoders to evade Antivirus and we will use polymorphic engines which are quite difficult to detect and fingerprint.

We will build Command and Control (C2) because network intrusion may be detected and compromised systems can be patched, some exploits only work once, to survive the reboot. C2 will be Stealth to avoid detection by DS, persistence to survive reboot, encryption for secure communication and minimising possibility of firewall interference.

This training has been taken by 1000+ security professionals and red team members worldwide to advance their pentesting and exploitation skills and we have received extremely positive feedback.

Lab has real world remote enterprise networks including different flavours of operating system such as windows and linux. Lab contains real world Firewalls, IDP/IPS, DMZ, Load Balancers, Web Application Firewalls, Active Directory etc. This course is for you if you want to pentest and exploit highly secured enterprise networks using cutting edge techniques. The training includes 50+ labs and 30+ challenges which are inspired by real world vulnerabilities and case studies. After the training attendees will get 1 month remote lab access free with 20 additional challenges and 5+ hours of HD videos of training walkthrough. Also, 1 month before the training, attendees will get videos on basic Assembly Language and Python Scripting which will help them in class.

This 3 day course will take place on the 10, 11th & 12th September 2018 at the Novotel London West
