Wow...I need to get on those guys' levels. Those guys ability to think outside the box is astounding. Don't get me wrong, there are alot of people on this forum that think I'm uber 1337 (mainly based off of my reputation as the diabolical doctor), but I will admit with the utmost humility...I don't know everything. These guys really made me think twice about how I look for vulnerabilities. +1 parad0x, great share.
Everyone else, I recommend looking through the POC's these guys wrote and truly try to understand what they are doing. Their methods are not *that* particularly complex, but...it's just the manner of how they went about finding these vulnerabilities. I only wish I could emulate that level of intelligence.
