_Overview
NanoCore is a RAT (Remote Admin Tool) used by cybercriminal groups such as APT33 (Refined Kitten) whose InitialAccess is varied, although it has been most commonly used through fake emails with .zipx extensions or with fake formats, which is commonly called phishing (T1566) or in this case, since it contains a file in the email and its objective is execution on disk to go further, it would be more accurate to call it Spearphishing (T1566.001).
The main potential of NanoCore is usually to steal data from the computer and user once it has gained access to the disk, but once it is inside, it could perform any action from the outside, and, of course it depends of version.
To this analysis, I have divided into two parts, which is usually a common practice in which we observe first statically everything we can get in the shortest possible time and then a dynamic in which we will see how it behaves, although, we will lose information if we do not monitor properly or not debug.
