A group of researchers put together this finger pushing robot to crack lock screens on android phones. While I’m sure this will method will work on non-android phones, I know that the IOS lock screen can have a self destruct feature after so many failed attempts. According to the article they will demo this unit at the upcoming Def Con conference in Las Vegas. Apparently on most phones this thing will find your password in under 24 hours, in some cases minutes using profiling algorithms.
The bot is inspired by a 3D printer design called the delta bot. I’m sure this will lead to the evolution of different unlock screens using facial recognition or more gesture based unlocks. The IOS wipe-after-so-many-bad-attempts is also a good solution assuming there is no legal issue with implementing it.
I personally just think it’s cool watching this thing punch away at the screen, but there’s a full writeup over at Forbes about it if you’re interested in learning more.
