I've learned more about Metasploit within one morning of SEC660 than other penetration testing courses in their entireties.
I am very impressed at how well the instructor conveyed the material in SEC660. This is a hard topic, but I have a lot I can take home with me and practice. This material puts me at that next level.
SEC660: Advanced Penetration Testing, Exploit Writing, and Ethical Hacking is designed as a logical progression point for those who have completed SANS SEC560: Network Penetration Testing and Ethical Hacking, or for those with existing penetration testing experience. Students with the prerequisite knowledge to take this course will walk through dozens of real-world attacks used by the most seasoned penetration testers. The methodology of a given attack is discussed, followed by exercises in a hands-on lab to consolidate advanced concepts and facilitate the immediate application of techniques in the workplace. Each day of the course includes a two-hour evening boot camp to drive home additional mastery of the techniques discussed. A sample of topics covered includes weaponizing Python for penetration testers, attacks against network access control (NAC) and virtual local area network (VLAN) manipulation, network device exploitation, breaking out of Linux and Windows restricted environments, IPv6, Linux privilege escalation and exploit-writing, testing cryptographic implementations, fuzzing, defeating modern OS controls such as address space layout randomization (ASLR) and data execution prevention (DEP), return-oriented programming (ROP), Windows exploit-writing, and much more!
Attackers are becoming more clever and their attacks more complex. To keep up with the latest attack methods, you need a strong desire to learn, the support of others, and the opportunity to practice and build experience. This course provides attendees with in-depth knowledge of the most prominent and powerful attack vectors and furnishes an environment to perform these attacks in numerous hands-on scenarios. The course goes far beyond simple scanning for low-hanging fruit and shows penetration testers how to model the abilities of an advanced attacker to find significant flaws in a target environment and demonstrate the business risk associated with these flaws.
SEC660 starts off by introducing advanced penetration concepts and providing an overview to prepare students for what lies ahead. The focus of day one is on network attacks, an area often left untouched by testers. Topics include accessing, manipulating, and exploiting the network. Attacks are performed against NAC, VLANs, OSPF, 802.1X, CDP, IPv6, VOIP, SSL, ARP, SNMP, and others. Day two starts with a technical module on performing penetration testing against various cryptographic implementations, then turns to PowerShell and post exploitation, escaping Linux restricted environments and Windows restricted desktop environments. Day three jumps into an introduction of Python for penetration testing, Scapy for packet crafting, product security testing, network and application fuzzing, and code coverage techniques. Days four and five are spent exploiting programs on the Linux and Windows operating systems. You will learn to identify privileged programs, redirect the execution of code, reverse-engineer programs to locate vulnerable code, obtain code execution for administrative shell access, and defeat modern operating system controls such as ASLR, canaries, and DEP using ROP and other techniques. Local and remote exploits as well as client-side exploitation techniques are covered. The final course day is devoted to numerous penetration testing challenges that require students to solve complex problems and capture flags.
Among the biggest benefits of SEC660 is the expert-level hands-on guidance provided through the labs and the additional time allotted each evening to reinforce daytime material and master the exercises.
You Will Learn:
- How to perform penetration testing safely against network devices such as routers, switches, and NAC implementations.
- How to test cryptographic implementations.
- How to leverage an unprivileged foothold for post exploitation and escalation.
- How to fuzz network and stand-alone applications.
- How to write exploits against applications running on Linux and Windows systems.
- How to bypass exploit mitigations such as ASLR, DEP, and stack canaries.
Course Syllabus
SEC660.1: Network Attacks for Penetration Testers
Overview
Day one serves as an advanced network attack module, building on knowledge gained from SEC560: Network Penetration Testing and Ethical Hacking. The focus will be on obtaining access to the network; manipulating the network to gain an attack position for eavesdropping and attacks, and for exploiting network devices; leveraging weaknesses in network infrastructure; and taking advantage of client frailty.

SEC660.2: Crypto and Post Exploitation
Overview
Day two starts by taking a tactical look at techniques that penetration testers can use to investigate and exploit common cryptography mistakes. We begin by building some fundamental knowledge on how ciphers operate, without getting bogged down in complex mathematics. Then we move on to techniques for identifying, assessing, and attacking real-world crypto implementations. We finish the module with lab exercises that allow students to practice their newfound crypto attack skill set against reproduced real-world application vulnerabilities.
The day continues with advanced techniques but focuses more on post exploitation tasks. We leverage an initial foothold to further exploit the rest of the network. We abuse allowed features to escape restricted environments. First we will build up knowledge of local restrictions on hosts. Once we establish a set of possible restrictions, we leverage that knowledge to circumvent them. We will cover the core components that restrict the desktop and a variety of escape possibilities. The Windows escape exercise is a perfect, real-world demonstration of the risks of relying on obfuscation and blacklisting to thwart attacks.
As a major factor in post exploitation, we cover both exploiting administrators use of PowerShell and PowerShell attack tools. We'll use Metasploit alternatives like PowerShell Empire to escalate privileges, pivot, and deliver additional payloads. The day ends with a challenging boot camp exercise against a full network environment comprised of a variety of modern, representative, and fully patched systems with no obvious remote vulnerabilities.

SEC660.3: Python, Scapy, and Fuzzing
Overview
Day three brings together the multiple skill sets needed for creative analysis in penetration testing. We start by discussing product security testing. The day continues with a focus on how to leverage Python as a penetration tester - the aim is to help students unfamiliar with Python start modifying scripts to add their own functionality, while also helping seasoned Python scripters improve their skills. Once we leverage the Python skills in creative lab exercises, we move on to leveraging Scapy for custom network targeting and protocol manipulation. Using Scapy, we examine techniques for transmitting and receiving network traffic beyond what canned tools can accomplish, including IPv6. Next, we take a look at network protocol and file format fuzzing. We leverage fuzzing to target both common network protocols and popular file formats for bug discovery. We use hands-on exercises to develop custom protocol fuzzing grammars to discover bugs in popular software. Finally, we carefully discuss the concept of code coverage and how it goes hand-in-hand with fuzzing. We will conduct a lab using the Paimei Reverse Engineering Framework and IDA Pro to demonstrate the techniques discussed.

SEC660.4: Exploiting Linux for Penetration Testers
Overview
Day four begins by walking through memory from an exploitation perspective as well as introducing x86 assembler and linking and loading. These topics are important for anyone performing penetration testing at an advanced level. Processor registers are directly manipulated by testers and must be intimately understood. Disassembly is a critical piece of testing and will be used throughout the remainder of the course. We will take a look at the Linux OS from an exploitation perspective and discuss privilege escalation. We continue by describing how to look for SUID programs and other likely points of vulnerabilities and misconfigurations. The material will focus on techniques that are critical to performing penetration testing on Linux applications.
We then go heavily into stack overflows on Linux to gain privilege escalation and code execution. We will first cover using a debugger to expose weak passwords. Then we will go over redirection of program execution and, finally, code execution. Techniques such as return to buffer and return to C library (ret2libc) will be covered, as well as an introduction to return-oriented programming. The remainder of the day takes students through techniques used to defeat or bypass OS protections such as stack canaries and address space layout randomization (ASLR). The goal of this section is to expose students to common obstacles on modern Linux-based systems.
CPE/CMU Credits: 8
Topics
- Stack and dynamic memory management and allocation on the Linux OS
- Disassembling a binary and analyzing x86 assembly code
- Performing symbol resolution on the Linux OS

- Defeating stack protection on the Linux OS
- Defeating ASLR on the Linux OS
SEC660.5: Exploiting Windows for Penetration Testers
Overview
Day five starts off covering the OS security features (ASLR, DEP, etc.) added to the Windows OS over the years as well as Windows-specific constructs, such as the process environment block (PEB), structured exception handling (SEH), thread information block (TIB), and the Windows application programming interfaces (API). Differences between Linux and Windows will be covered. These topics are critical in assessing Windows-based applications. We then focus on stack-based attacks against programs running on the Windows OS. After finding a vulnerability in an application, the student will work with Immunity Debugger to turn the bug into an opportunity for code execution and privilege escalation. Advanced stack-based techniques such as disabling data execution prevention (DEP) are covered. Client-side exploitation will be introduced, as it is a highly common area of attack. We continue with the topic of return-oriented programming (ROP), demonstrating the technique against a vulnerable application, while looking at defeating hardware DEP and address space layout randomization (ASLR) on Windows 7, Windows 8, and Windows 10. We then have a module on porting over an exploit into the Metasploit Framework and on how to quickly identify bad characters in your shellcode and as input into a program. Finally, we will take a quick look at shellcode and the differences between shellcode on Linux and Windows, followed by a ROP challenge.

Who Should Attend
- Network and Systems Penetration Testers: SEC660 provides penetration testers with the training they need to perform advanced testing against known or unknown applications, services, and network systems. And the course gives students the expertise to perform complex attacks and develop their own exploits for existing and new frameworks.
- Incident Handlers: SEC660 gives incident handlers the knowledge they need to understand advanced threats, as handlers are often tasked with determining the threat level associated with an attack. The ability to understand advanced attack techniques and analyze exploit code can help a handler identify, detect, and respond to an incident.
- Application Developers: SEC660 teaches developers the ramifications of poor coding. Often, a developer or code reviewer is required to clearly demonstrate the threat and impact of a coding error. This course provides developers with the knowledge to create proof-of-concept exploit code and document their findings.
- IDS Engineers: SEC660 teaches IDS professionals how to analyze exploit code and identify weaknesses. This knowledge can be used to write better IDS signatures and understand the impact of an alert.

Author Statement
When conducting an in-depth penetration test, we are often faced with situations that require unique or complex solutions to successfully pull off an attack, mimicking the activities of increasingly sophisticated real-world attackers. Without the skills to identify and implement those solutions, you may miss a major vulnerability or not properly assess its business impact. Target system personnel are relying on you to tell them whether an environment is secured. Attackers are almost always one step ahead and are relying on our nature to become complacent, even with regard to the very controls we worked so hard to deploy. This course was written to keep you from making mistakes others have made, teach you cutting-edge tricks to thoroughly evaluate a target, and provide you with the skills to jump into exploit development.
