CyFi is the co-founder of DEFCON Kids who revealed her zero-day exploit in games on iOS and Android devices which she call 'Time Traveler'. She first discovered the flaw around January 2011 because she "started to get bored" with the pace of farm-style games. Most of the games she discovered the exploit in have time-dependent factors. Manually advancing the phone or tablet's clock forced the game further ahead than it really was, opening up the exploit.


She really likes coffee, but her mom doesn’t let her drink it.

She has spoken publicly numerous times, usually at art galleries as a member of “The American Show,” an underground art collective based in San Francisco.
