About

The goal of Xplico is extract from an internet traffic capture the applications data contained.
For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP), FTP, TFTP, and so on. Xplico isn’t a network protocol analyzer. Xplico is an open source Network Forensic Analysis Tool (NFAT).

Features

  • Protocols supported: HTTP, SIP, IMAP, POP, SMTP, TCP, UDP, IPv6, …;
  • Port Independent Protocol Identification (PIPI) for each application protocol;
  • Multithreading;
  • Output data and information in SQLite database or Mysql database and/or files;
  • At each data reassembled by Xplico is associated a XML file that uniquely identifies the flows and the pcap containing the data reassembled;
  • Realtime elaboration (depends on the number of flows, the types of protocols and by the performance of computer -RAM, CPU, HD access time, …-);
  • TCP reassembly with ACK verification for any packet or soft ACK verification;
  • Reverse DNS lookup from DNS packages contained in the inputs files (pcap), not from external DNS server;
  • No size limit on data entry or the number of files entrance (the only limit is HD size);
  • IPv4 and IPv6 support;
  • Modularity. Each Xplico component is modular. The input interface, the protocol decoder (Dissector) and the output interface (dispatcher) are all modules;
  • The ability to easily create any kind of dispatcher with which to organize the data extracted in the most appropriate and useful to you;
