[http://networkminer.sourceforge.net/ NetworkMiner] is a Network Forensic Analysis Tool (NFAT) for Windows. [http://sourceforge.net/apps/mediawiki/networkminer/index.php?title=NetworkMiner 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.

Some common tools for malware analysis include simple programs like [[strings]]. More complex analysis can be conducted by looking at the headers of executables with programs like [[PEiD]] and [[PeExplorer]]. Finally, the most complete analysis can be done with debuggers like [[IDA Pro]] and [[OllyDbg]].  
  
The purpose of NetworkMiner is to collect data (such as forensic evidence) about hosts on the network rather than to collect data regarding the traffic on the network. The main view is host centric (information grouped per host) rather than packet centric (information showed as a list of packets/frames).

NetworkMiner performs [[OS fingerprinting]] based on TCP SYN and SYN+ACK packet by using [[OS fingerprinting]] databases from p0f (by Michal Zalewski) and Ettercap (by Alberto Ornaghi and Marco Valleri). NetworkMiner can also perform [[OS fingerprinting]] based on DHCP packets (which usually are broadcast packets) by making use of the Satori (by Eric Kollmann) [[OS fingerprinting]] database from FingerBank. NetworkMiner also uses the MAC-vendor list from Nmap (by Fyodor).

NetworkMiner can extract files and certificates transferred over the network by parsing a PCAP file or by sniffing traffic directly from the network. This is a neat function that can be used to extract and [http://sourceforge.net/apps/mediawiki/networkminer/index.php?title=Save_media_files save media files] (such as audio or video files) which are streamed across a network.

A feature which is planned to be included in future versions of NetworkMiner is to use [http://sourceforge.net/apps/mediawiki/spid/index.php?title=Main_Page statistical methods to do protocol identification] (protocol fingerprinting) of a TCP session or UDP data. This means that instead of looking at the port number to guess which protocol is used on top of the TCP/UDP packet NetworkMiner will identify the correct protocol based on the TCP/UDP packet content. This way NetworkMiner will be able to identify protocols even if the service is run on a non-standard port. Richard Bejtlich calls this type of functionality [http://taosecurity.blogspot.com/2006/09/port-independent-protocol.html "Port Independent Protocol Identification" (PIPI)].

Analyzing malware, or malicious software, is more of an art than a technique. Because of the wide nature of these products, there are limitless ways to hide functionality.

Some common tools for malware analysis include simple programs like strings. More complex analysis can be conducted by looking at the headers of executables with programs like PEiD and PeExplorer. Finally, the most complete analysis can be done with debuggers like IDA Pro and OllyDbg.
