Hello fedi!

I have an .MVAX #firmware #update file for an MV Silicon chip (unknown model).

Has someone already encountered those? And if yes, is there some documentation, tooling or existing #ReverseEngineering work done of that format?

For the record, the file magic (first 8 bytes) is as follow:
4D 56 B5 58 05 01 13 00

And the end of the file contains the following (no spaces, wrapping is mine):

MVSKeyFileMVBP10<0x90>0xBE>SIMPLEs
<0xD3><0x9A>.<0x90><0xD9>
MVSILICONKEYFL<0x00><0x00>
<0xFF><0xBD><0x00>0x00>

Thanks in advance for your help!!

Shattering the eyeglass: Using Kaitai Structs to dissect the eyeglass’ contents

by @beet_keeper

In my post from 2012: Genesis of a File Format, I created a new file format – the Eyeglass file format. The format provides a mechanism to persist information about a patient’s eye health following a checkup at an opticians. Today in 2023 we can use the format to understand how to make use of Kaitai Structs for understanding file formats.

Given the disclaimer that I am not actually an optician and that the format is purely illustrative, let’s look at the eyeglass again below.

What information is in a file format identification report?

by @beet_keeper

In early 2022, I was finally able to get around to writing a paper that I had been thinking about for the better part of a decade. The paper, “Fractal in Detail: What Information Is in a File Format Identification Report?” was published in the Code4Lib journal Issue 53.

The paper takes a deep dive into the fractal contents of file format identification reports exported from tools like Siegfried and DROID.

Let’s take a brief look the article and its contents below.
