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.

Chapter 9 – The Reverse Card – Weaponization of IOCs and OSINT for Defense

In this chapter, we talked about weaponizing IOCs and turning the tables on attackers by preventing their malware from executing at all – or limiting its ability to communicate with those that control it. You were tasked with collecting IOCs via OSINT about a Monero coin-mining campaign and implementing strategies to mitigate it within your environment:

  1. The file hashes you should have been able to gain are 240fe01d9fcce5aae311e906b8 311a1975f8c1431b83618f3d11aeaff10aede3 and 8ecffbd4a0c3709cc98b036a895289f3 3b7a8650d7b000107bafd5bd0cb04db3.

    a. The best mitigations for Windows servers would be to block the initial PowerShell command utilized to download and execute the installer for the XMRig binary – some research on the internet should have led you to the command being utilized.
