Intro It's been a while since part 3, though not for lack of progress on the analysis. The work over the last month or so has largely consisted of persistent analysis of the binary. There's not that much to share in terms of exciting updates,...
Intro In the previous post I introduced what we're doing so if you haven't read that, do that first or this won't make much sense. At the end of the previous post we concluded that we'll need to reverse engineer the driver to understand the...
