Network forensics is a method of obtaining and analysing digital evidences from network sources. Network forensics includes data acquisition, selection, processing, analysis and presentation to investigators. Due to high volumes of transmitted data the acquired information can be incomplete, corrupted, or disordered which makes further reconstruction dicult. In this paper, we address the issue of advanced parsing and reconstruction of incomplete, corrupted, or disordered data packets. We introduce a technique that recovers TCP or UDP conversations so they could be further analysed by application parsers. Presented technique is implemented in a new network forensics tool called NetFox.Detective. We also discuss current challenges in parsing webmail communication, SSL decryption and Bitcoins detection.
