The firmware image used is for the WAGN hardware version 1. And there you have it. The LZMA files can be extracted with dd and then decompressed with the lzma utility. 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. SquashFS is a very common embedded file system. I was researching more on this topic late last evening and found an interesting project work by Mr. 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!

Running file against our modified SquashFS image gives us much better results:. 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!

So how do we find an unknown signature inside a 4MB binary file? Alex Gold 28 May at And there you have it.

Re-running binwalk against the original firmware image, we see that it now correctly identifies the SquashFS entry:. 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.

Since each uImage header is followed by LZMA compressed data, this information appears to be legitimate.

There are some other sections as well, but again, these are very small, much too small to be a file system:. The LZMA files can be extracted with dd and then decompressed wqg120n the lzma utility.

SquashFS is a very common embedded file system. 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. 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.

Binwalk breaks out most of the information contained in these uImage headers, including their descriptions: Posted by IndiaBuddy at cksco Different sections inside of firmware images are often aligned to a certain size.

There are a lot of false positive matches these will be addressed in the up-coming 0.

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:. Taking a look at the strings output, we see references to firmwaare U-Boot boot loader and the Linux kernel.

The firmware image used is for the WAGN hardware version 1. This definitely looks like a valid SquashFS image!

Running strings against them confirms that they are in fact the U-Boot and Linux kernel wzg120n. I am really impressed and you do an appreciative work.
