Background
You work as a SOC analyst for a remote facility of a large corporate finance organization. An individual you support has just reported a problem with their system. Your task is to analyze the attack and collect as much information as you can to describe what type of attack occurred and identify the specific aspects of the attack that may be used to describe it. Use the techniques you learned from the previous lab assignment when reviewing both the attack as it took place and the analysis process that was used. First, review the following video and perform the exercise it asks of you. Make sure you take good notes, this will be helpful for the quiz portion of the assignment.
Now that you have reviewed the attack as it has taken place and the some of the analysis process used, answer the following questions about the attack and course of action required to perform the analysis of a specific threat.
Outcomes
Hope you found the above exercise interesting and informative. I hope you noticed that it acts as an introduction to another course you will be allowed to take in the future, Malware Analysis and Reverse Engineering. After completing this assignment, you should have a better feel for how analytics is performed, and the observations observed mapped to STIX objects we have been learning and the relationships between them. This should aid you when working on your final report. I also hope you noticed how virtualization was again used, this time to create a safe environment to run the “sample” malware that was used. Virtualization is a powerful tool for many of the analyst tools that are used within this environment. Additional tools used within the example were tools that allowed you to examine task and registry key entries. The combination of these tools plus forensic tools and of course a good Security Information Sharing tool are key to the analysis and reporting of incidents.
