I came to the conclusion that the blind SQL injection attack vectors we use are very old, slow, and there is a huge room for improvement to make them much faster and efficient.

I spent some time designing new highly optimized SQL injection vectors and I wrote a paper where I documented these vectors. It got accepted to present this research at various conferences such as Hackfest Quebec, B-Sides Philly, BugCON Mexico, DragonJAR Colombia and Hack in Paris (which I missed because I was severely jet-lagged and I feel very ashamed to say so).

For a self-explanatory and condensed version of the paper, you can find the slides of the talk HERE.

If you prefer a thorough explanation, you can find the paper in .txt format HERE.
