Xplico is an IP traffic decoder that extracts data from an Internet traffic capture. From a pcap file, it can extracts each email (POP, IMAP, and SMTP protocols), all HTTP content, VoIP calls (SIP, RTP, H323, MEGACO, MGCP), IRC, MSN, and so on. It isn't a packet sniffer or a network protocol analyzer, but rather an IP/Internet traffic decoder or network forensic analysis tool (NFAT).
Gpart is a small tool which tries to guess which partitions are on a PC harddisk in case the primary partition table was damaged. It works by scanning through the device (or file) given on the commandline on a sector basis. Each guessing module is asked if it thinks a filesystem it knows about could start at a given sector. Several filesystem guessing modules are built in, and others can be added dynamically.
The RegLookup project is devoted to direct analysis of Windows NT-based registry files. RegLookup provides command line tools, a C API, and a Python module for accessing registry data structures. The project has a focus on providing tools for digital forensic examiners (though it is useful for many purposes), and includes algorithms for retrieving deleted data structures from registry hives.
Picviz is a parallel coordinates plotter which enables easy scripting from various types of input (such as tcpdump, syslog, iptables logs, or Apache logs) to visualize your data and discover interesting results quickly. Its primary goal is to graph data in order to be able to quickly analyze problems and find correlations among variables. With security analysis in mind, the program has been designed to be very flexible, able to graph millions of events.
CarvPath (libcarvpath) is a library aimed at computer forensic tools that process disk and/or memory dump images or other large data files. The library allows the creation and manipulation of CarvPath annotations, which are a way to annotate partitions, files, alternate streams, processes etc. within a disk or memory image as a string. Entities within a CarvPath notation can be fragmented and/or nested, and allow for the expression of 'sparse' fragments within an entity. The CarvPath annotations resemble a path string in a filesystem, and thus present a basis for the interaction between computer forensics tools and the CarvPath-based user space file-system, CarvFs.
CarvFS is a user space FUSE filesystem aimed at computer forensic tools that process disk and/or memory dump images or other large data files. The filesystem allows CarvPath-aware tools to use CarvPath annotations as a way to designate partitions, files, alternate streams, processes etc. within a disk or memory image as a string, making them available trough the filesystem as a pseudo file that can be handed to other tools. This removes the need to copy the information out of the disk image and reduces storage requirements.
mbrChunker is a utility that allows you to mount raw disk images (created by dd, dcfldd, dc3dd, ftk imager, etc.) and create VMDK files. It does this by taking the raw image, analyzing the master boot record (physical sector 0), and getting specific information that is need to create a working VMDK file that points to your raw image. It can also extract information such as heads, cylinders, and sectors per track. With version 0.3.15, the tool now has the ability to search for hex byte offsets within any binary file. It will give you the byte location for every hex pattern found. More information about this can be found in the README.
