Malware Analysis Techniques

By: Dylan Barker

Overview of this book

Malicious software poses a threat to every enterprise globally. Its growth is costing businesses millions of dollars due to currency theft as a result of ransomware and lost productivity. With this book, you'll learn how to quickly triage, identify, attribute, and remediate threats using proven analysis techniques. Malware Analysis Techniques begins with an overview of the nature of malware, the current threat landscape, and its impact on businesses. Once you've covered the basics of malware, you'll move on to discover more about the technical nature of malicious software, including static characteristics and dynamic attack methods within the MITRE ATT&CK framework. You'll also find out how to perform practical malware analysis by applying all that you've learned to attribute the malware to a specific threat and weaponize the adversary's indicators of compromise (IOCs) and methodology against them to prevent them from attacking. Finally, you'll get to grips with common tooling utilized by professional malware analysts and understand the basics of reverse engineering with the NSA's Ghidra platform. By the end of this malware analysis book, you’ll be able to perform in-depth static and dynamic analysis and automate key tasks for improved defense against attacks.

Chapter 2 – Static Analysis – Techniques and Tooling

The challenges in Chapter 2 cover the basic static analysis of binaries. The answers are as follows:

Challenge 1

  1. The SHA256 sum of the sample is B6D7E579A24EFC09C2DBA13CA906227 90866E017A3311C1809C5041E91B7A930.
  2. The ssdeep of the sample is 3072:C5OLkQW8JS0k0wcBalDIs3hlAp5+hQQE89X3Qo+PgaE3:CsWnGYlAp5+hR9sYaE.
  3. Utilizing what we've learned from static cryptographic hashes, we can utilize OSINT sources such as VirusTotal to learn that this sample corresponds with the SolarMarker family of malware.

Challenge 2

For this challenge, you could locate the kill-switch domain for WannaCry just by utilizing the strings utility! The domain you should have uncovered was as follows:
