My sister installed AirSig last week. She is so exciting about this new techknology and she won‘t stop writing strange words in the air. She want me to take a guess about what she wrote in the air...Of course I could not know what she wrote. Even I write exaclty what she wrote in the air, AirSig will only authenicate her motion...That is fantastic..But... I told her not to use AirSig because secrets still could be found somewhere in the filesystem.
Guess what? She does not believe what I said to her. I have to prove it so I take a look at her phone. It‘s ridiculous...everything inside AirSig is plaintext only...I don‘t have to worry about decryption on it.
You guys could see the Facebook info as below. I show this screenshot to my sister...She is so scared and she swear she won‘t save any credentials in AirSig any more...
