These facilities tend the internet users to upload and download pirated softwares, movies and other similar digital assets which violates all copyrights. The P2P protocol is working behind such online sharing websites and resources. The cyber cell is very active now in various parts of the country to trace and fraudulent sharing of files when reported. So it is necessary to have an efficient mechanism to find the actual content which is being uploaded or downloaded from a particular machine as part of network forensic investigation. Usually P2P websites and services are blocked in enterprises and educational institutions to avoid sharing of unwanted digital assets and also to increase internet bandwidth. The proposed novel technique is based on network forensics which can be used for content level observation of P2P Bit Torrent protocol and regenerate original malicious content or session between malicious users for their prosecution in the court.
