Abstrakt
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. č
