‪Bypassing Control Flow Guard (CFG) in Win10 using RtlCaptureContext http://goo.gl/Fdi0Ha ‬
This blog post is the result of some research I did back in July of 2016, but did not have the possibility to publish before now. In June of 2016 Theori published a blog post on an Internet Explorer vulnerability which was patched in MS16-063, the exploit they wrote was for Internet Explorer 11 on Windows 7, and as their own blog post indicates the exploit will not work on Windows 10 due to the mitigation technology called Control Flow ...

Since cars have become computers with wheels, it's time to look at their computing systems with more detail and focus. Increasingly more remote pathways into them. Danger Will Robinson. Danger.

(Had a lot of interesting cautionary tales at PacSec, expect more at CanSecWest.)

Let me leave you folks for the evening with a photo that was impossible a few months ago.
A photo I consider beautiful and magnificient.

The new DJI Mavic is the most stable thing I've ever flown.
Hover is stay in one spot rock solid. Unmoving. Eerie stable. Tripod stable. Long exposure at night in the air stable.

This was a three second exposure at night.

This gives you a really unfair advantage, because most ...
