.Warning
Don't trust blindly on the results, some might not be accurate. I pretty much used as reference PE-bear parser, winchecksec, Process Hacker, and narly. Thank you to all of them.
I put this together in a day to save some time during a specific assignment. It worked for me but it hasn't been thoroughly tested. You have been warned, use at your own risk.
I'll be updating and maintining this, so any issues you may find please let me know. I plan to add a few more mitigations later.
References
Besides the references mentioned before, if you want to write your own extension (or contribute to this one) the Advanced Windows Debugging book and the WinDbg SDK are your friends.
