The life of an information security professional is a hectic one. It seems like you are fighting fires every day and always behind the eight ball. You know you should be proactively hunting for emerging threats in your network but the tools at your disposal simply do not scale. You can check each machine individually for hardening and policy compliance but you have many thousands of endpoints deployed, it is hard enough to keep up with the alerts.
You try to keep across the latest malware trends and threat Intel feeds. You might even receive a tipoff that your network is compromised by a specific variant of malware of an APT group. You wish there was a way for you to easily inspect all your endpoints for the indicators, digging deeper into any machines which might be compromised.
About this course
This 2 day course is an introduction to forensic analysis and incident response for information security professionals. We use a new open source endpoint visibility tool called Velociraptor, developed by Velocidex Enterprises. Velociraptor is a powerful endpoint tool – you can hunt for artifacts in minutes across thousands of endpoints and perform advanced forensic analysis on the endpoint, rapidly and at scale. Welcome to the future of DFIR!
This training event is run by the company behind Velociraptor - you will learn from the developers and practitioners who use Velociraptor every day to respond to incidents and investigate breaches. The course is run in person over 2 days with hands on practical instructor led classes. Course materials and detailed preparation instructions will be distributed to participants the week prior to the course. Although this course uses the Velociraptor tool extensively, it focuses on understanding the underlying techniques and when and how they may be applied - even by other opensource or commercial forensic tools. You will learn actionable skills you can apply immediately to hunt for intrusions across your enterprise.
You will receive 12 months of access to the online portal. The online portal contains all course materials as well as updated course content and allows participants to discuss their experiences with implementing the knowledge and techniques gained from the course.
Installation and introduction to the UI
The old way of performing in-depth forensic analysis and incident response with your existing tools is clearly not adequate or scalable to many endpoints. It is just too time consuming to analyze many machines, acquire large disk images, and memory, let alone actively hunt for indicators of compromise across your entire network.
You heard that Velociraptor, an advanced open source endpoint visibility tool, is the ideal tool for effectively investigating, hunting and monitoring your endpoints with minimal fuss.
You are excited to install Velociraptor and deploy it to your entire infrastructure. This module is for you! In this module we will deploy Velociraptor and gain an introduction to the basic operation of the tool. We will learn the architecture and the unique mindset behind the tool.
- Installing a typical secure Velociraptor server on a cloud VM.
- Deploy Velociraptor clients on a typical Windows network using group policy.
- Introduction to the Velociraptor Query Language (VQL). It is the workhorse behind the tool and mastering VQL will provide you with the flexibility you need to adapt to rapidly changing challenges.
Interactive forensic investigation
Velociraptor puts the power of experienced digital forensic investigators at your finger tips! This module will cover at a high level the basics of modern forensic analysis techniques. You will now be able to apply these techniques to answer many questions – from determining evidence of malware execution, detecting persistent malware to uncovering malicious user activity and determining ex-filtration of proprietary data.
Basics of Windows Forensics
- NTFS Overview
- Data Streams and the $MFT
- Recovering evidence of deleted files from $MFT and $I30 carving
- What is the windows Registry?
- Inspecting user hives and user profiles.
- Common registry based malware persistent mechanisms
Windows Management Instrumentation (WMI)
- What is WMI and what information is exposed with it?
- Lateral movement and privilege escalation using WMI – an attacker’s favorite!
- WMI persistence mechanisms (Filter/consumer bindings)
System Resource Usage Monitor (SRUM)
- The SRUM database can help us determine evidence of past executions, connected networks, bytes sent/received and much more.
Windows Event Logs are the cornerstone of windows auditing
- How are event logs structured?
- What are event Ids and how do they relate to messages?
- Some examples of common event log messages: lateral movement, powershell abuse etc.
Interactive investigation – collecting artifacts
- Throughout this module we will use Velociraptor to gain experience in analysis and searching for the discussed artifacts.
Triage and data collection – collecting data without an agent
A remote user is suspected of being compromised. The user is on the NBN and therefore due to limited bandwidth, can not upload vast amounts of data quickly. You need to triage their system to determine if they are comprised. You would like to acquire memory, critical files and capture as much of system state as possible. Unfortunately, the user is not command line savvy – but luckily they are really good at double clicking a binary!
In this module we learn how to perform offline collection with Velociraptor. We prepare an automatic collection package which simply acquires system state when double clicked.
- Process listing, VADs, Mutants, DLLs loaded
- Full memory capture
- Collect file sets – registry, $MFT etc.
- Configuring autoexec Velociraptor for simple double click execution.
Lateral movement and hunting
You have discovered evidence of compromise on some of your systems. Your boss wants to know if the attackers have laterally moved through your network and the extent of compromise. You would like to hunt for the indicators.
- Hashes and file pattern based searches (Using $MFT analysis and directory walking).
- Yara and Signature based searching. Searching both files and memory for patterns
- Performance management of endpoints
Monitoring for events
You have learned so much in this course about how to detect malware, lateral movement and compromise. But so far, everything was reactive – we were looking at forensic evidence left behind after the fact. What you really want is to design monitoring and alerting that will let you know when evidence of compromise are found in real time. Luckily Velociraptor is a complete endpoint monitoring and response tool!
- Introduction to Velociraptor’s event monitoring framework
- Windows Event Log forwarding and classification. Event log enrichment and prioritization.
- Monitoring for changes in system state: New file executions and High risk files such as office macros and remote PowerShell
This course should not be missed!
You have heard about Velociraptor and how it makes DFIR easy and accessible. Learn what all the buzz is about from the people who wrote it! This is a rare opportunity to become involved and support this open source tool.
Velocidex Enterprises was founded by well established industry professionals with many years of proven expertise in the development of digital forensic software and its use to support a wide range of digital forensic investigations and cyber breach response cases.
Velociraptor aims to provide the “last step” in the process of digital forensic investigations, security monitoring and threat hunting. We already know a great deal about how to investigate computer systems and monitor for malicious activities. Velociraptor aims to encapsulte this industry knowledge and empower both experts and novices to leverage it, to collect and analyse evidence of malicious activities with speed and precision.
This training event will be held at Saxons Training Facilities in the Sydney CBD. The venue is a short walk from Wynyard station.
Attendees should bring their own laptop. We will be working on cloud instances so a current web browser such as Chrome is essential.
