A 10 year old girl from California who goes by the name of “CyFi” has discovered a useful exploit in some iOS and Android games. She likes to play farmville esque games which require timing to grow crops, populations etc.
CyFi has reported that by changing the time on the phone crops, populations, restaurants, etc can move quicker and thus get you to the next level or the next task in these style games. Although some publishers have plugged the hole, it seems you can even beat that by disconnecting the devices wi-fi or only increasing the time in small increments.
Zynga’s popular Farmville is available on iOS but not Android yet. Also their follow up smash hit Cityville is not available on either platform as of yet. Perhaps that’s partly attributed to this exploit.
CyFi gave a full report on this in DefCon Kids a part of DefCon 19. TDG had a crew on the ground in Las Vegas for “Hacker Week” which included Def Con 19, DefCon Kids and the Black Hat conference.
