NetworkMiner is an open source Network Forensic Analysis Tool (NFAT) for Windows (but also works in Linux / Mac OS X / FreeBSD). NetworkMiner can be used as a passive network sniffer/packet capturing tool in order to detect operating systems, sessions, hostnames, open ports etc. without putting any traffic on the network. NetworkMiner can also parse PCAP files for off-line analysis and to regenerate/reassemble transmitted files and certificates from PCAP files.
NetworkMiner makes it easy to perform advanced Network Traffic Analysis (NTA) by providing extracted artifacts in an intuitive user interface. The way data is presented not only makes the analysis simpler, it also saves valuable time for the analyst or forensic investigator.
Since the first release in 2007, NetworkMiner has become a popular tool among incident response teams as well as law enforcement. NetworkMiner is today used by companies and organizations all over the world.
NetworkMiner can extract files, emails and certificates transferred over the network by parsing a PCAP file or by sniffing traffic directly from the network.
User credentials (usernames and passwords) for supported protocols are extracted and displayed under the "Credentials" tab. The credentials tab sometimes also show information that can be used to identify a particular person, such as user accounts for popular online services like Gmail or Facebook.
Another very useful feature is that the user can search sniffed or stored data for keywords. NetworkMiner allows the user to insert arbitrary string or byte-patterns that shall be searched for with the keyword search functionality.
NetworkMiner Professional can be delivered either as an Electronic Software Download (ESD) or shipped physically on a USB flash drive. The product is exactly the same, regardless of delivery method. NetworkMiner is a portable application that doesn't require any installation, which means that the USB version can be run directly from the USB flash drive. However, we recommend that you copy NetworkMiner to the local hard drive of your computer in order to achieve maximum performance.
