NetworkMiner

NetworkMiner is a Network Forensic Analysis Tool (NFAT) for Windows. 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.

CapLoader logo

CapLoader

CapLoader is a Windows tool designed to handle large amounts of captured network traffic in the tcpdump/libpcap format (PCAP). CapLoader displays the contents of opened PCAP files as a list of TCP and UDP flows. Users can select the flows of interest and quickly filter out those packets from the loaded PCAP files. Sending the selected flows/packets to a packet analyzer tool like Wireshark or NetworkMiner is then just a mouse click away.

RawCap

RawCap is a tiny (23 kB) command line sniffer for Windows. You can sniff packets with RawCap without having special network drivers (like WinPcap) installed. No installation is required, just download RawCap.exe and start sniffing!
