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.
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.
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.
