Unfortunately, due to the lack of public access to private prison contracts, most of the details are unknown. Shortly before her death, the woman reported that she had been raped and assaulted by male inmates who were housed in the same cell block. She also reported being sexually humiliated by a GEO guard after reporting to the warden that guards allowed male and female inmates to have sex. A state audit showed that the jail barely kept the minimum number of guards required in the contract.

Embedded SystemsTutorials The ability to analyze a firmware image and extract data from it is extremely useful. It can allow you to analyze an embedded device for bugs, vulnerabilities, or GPL violations without ever having access to the device.

The firmware image used is for the WAGN hardware version 1. Taking a look at the strings output, we see references to the U-Boot boot loader and the Linux kernel. This is encouraging, as it suggests that this device does in fact run Linux, and U-Boot is a very common and well documented boot loader: There are a lot of false positive matches these will be addressed in the up-coming 0.

Binwalk has found two uImage headers which is the header format used by U-Booteach of which is immediately followed by an LZMA compressed file. Binwalk breaks out most of the information contained in these uImage headers, including their descriptions: Since each uImage header is followed by LZMA compressed data, this information appears to be legitimate.

The LZMA files can be extracted with dd and then decompressed with the lzma utility. Running strings against them confirms that they are in fact the U-Boot and Linux kernel images: SquashFS is a very common embedded file system.

So how do we find an unknown signature inside a 4MB binary file? Different sections inside of firmware images are often aligned to a certain size. This often means that there will have to be some padding between sections, as the size of each section will almost certainly not fall exactly on this alignment boundary.

When hexdump sees the same bytes repeated many times, it simply replaces those bytes with an asterisk to indicate that the last line was repeated many times. A good place to start looking for a file system inside a firmware image is immediately after these padded sections of data, as the start of the file system will likely need to fall on one of these aligned boundaries.

There are some other sections as well, but again, these are very small, much too small to be a file system: Running file against our modified SquashFS image gives us much better results: This definitely looks like a valid SquashFS image!

However, using the unsquashfs Re-running binwalk against the original firmware image, we see that it now correctly identifies the SquashFS entry: And there you have it. We successfully identified and extracted the boot loader, kernel and file system from this firmware image, plus we have a new SquashFS signature to boot!Is there some sort of walk through some where?

I’m stuck in the library.
