The occurrence of malicious software written in .NET languages is rapidly increasing. Extracting the information out of .NET executable file is therefore necessary step in order to fight against this kind of malware. In this paper, we propose methods to extract information out of .NET executable files, which are safe and platform independent. These methods include data type reconstruction, but also extraction of unique features such as TypeLib identifier or Module Version identifier. We also point out mistakes that are being done in this field so far. After implementing the proposed methods, we compare it with already existing .NET disassemblers yielding very good results. Extracted information are planned to be used in creation of detection patterns, clustering and other areas at Avast Software.
