A quick demo of how to identify "real" exported functions from a #obfuscated #IcedID dll file.
I'll also briefly touch on some #Ghidra tips, and how to extract #shellcode using a debugger.
A moderate sized thread😃

First, download the .zip in the screenshot.👇
Then unzip and locate the "rarest.db" file in the "scabs" folder.

[3/14] Drag the "rarest.db" file into Pe-Studio and navigate to the exports tab.
There are 11 exported functions here. 🧐
Most of them have junk names to throw off analysis.
One of them is "real", the rest are "decoys" which don't do anything if executed.

We'll touch on #cyberchef, #x64dbg and Speakeasy from fireeye to perform manual analysis and emulation of #shellcode.

To follow along, download the sample from the link below. Then transfer the .zip into a safe VM environment.
My VM is a mostly default Flare VM with SpeakEasy installed on top.

[3/23] Once unzipped (pw:infected), load the file into pe-studio for quick analysis. There isn't a lot interesting here, but take note that the file a 64-bit .dll with 4 exported functions.
