This year I believe, will mark my 15th year attending both Blackhat and DEFCON in Las Vegas. 
15 years?!! OMG where has the time flown to? This year will also mark the 26th year of Blackhat and the 31st year of DEFCON. Amazing. So to commemorate this,
I again created a new sticker to let everyone have some fun.
The sticker contains 11 digital ciphers. The goal is to see just by looking at it, if you can decipher which line is what cipher. I will post the answers in another page. Remember, there are 11 ciphers on this sticker. Can you name all? Can you find them all ?
Have fun and if you see me at DEFCON, stop me and ask for a sticker. I might challenge you with a question or swap sticker. Who knows. It's DEFCON Baby !
Enjoy, safe travels and will see you out there in Las Vegas.
