A flaw I found in EACs handle stripping in 2023.
Responsibly disclosed the same year and fixed since.

Most of this was written past 11PM, so code quality is 'not the best'.
But it was a fun weekend project and I like to look back at it :D.

Done with weekend project!
Goal was to get a faster pattern matcher for byte patterns than one I wrote a while ago utilizing SSE.

Depending on the length of the biggest sequence in a pattern the avg. speed for 262kb~ of data is 28ms~.
On the SSE one this was 124~ ms.

Image showing a C-String sequence in the read only section not being referenced in the whole binary.

Been up to some compile-time stuff with C++ and noticed that MSVC loves leaving global c-strings in read-only EVEN if they were used ONLY for compile-time ops.

Templates force you to have them global in order to use them.
This is with optimizations on.
Attached image of it not referencing anywhere.

Another type of roulette, just pop the top of the stack into EFlags after it returned to usermode from kernel
