GCC 2021 Online Lecture 6

Reverse APT Malware with Ghidra


In this course, we first introduce APT basic knowledge to realize the threat/behavior of the APT. Then we explain 3 different APT cases in Taiwan, Japan and Korea. For Taiwan’s case, Operation ShadowHammer is classical supply chain attack. JPCERT discovered the Taidoor malware is used in Operation Bitter Biscuit. Kimsuky, is the other state-sponsored APT compaign, targets many South Korean organizations.

To analysis these APTs, we then introduce the tools could be used for threat hunting, regularly tracking for hidden APT activities. The introduced tools include Moloch, ELK, Yara.

In the last part, we move to reverse the APT malware. Using Ghidra, we could analysis these APT malware. The technique to deal with APT samples are introduced here, e.g. PE Header, Decryption/Decoding, Shellcode, Data Structure and Import Table Hash.
