Year 1995, remember that cool movie with Angelina Jolie? Hackers? Good movie, remember when the hacker got caught and they took his pc to use it as evidence? That’s called computer forensics, your physical information is dug up and viewed in binary (that’s 01100010 01101001 01101110 01100001 01110010 01111001 00100000 01100011 01101111 01100100 01100101). Later converted into ASCII (that’s plain text), images, video, or anything really. And final step, used against you in court. Anyway this has been around for a while now and does stand up in court pretty solid.
Now with a huge tide of smartphones computer forensics has evolved into mobile phone forensics. More specifically Android forensics. And yes that does stand up in court as well. Your next question is “how does it work?”. Simple and efficient, by gaining root level access.
My point is this, if law enforcement can do this, or some private investigator, what makes you think your data can’t be compromised by some hacker. Say you do a lot of mobile banking and you receive emails from the bank server. You may delete them but the truth is, they are still in the physical memory of your phone. Do you really want someone seeing this? Â I know I don’t. But on the other hand if you are getting a divorce and your soon to be ex spouse has an Android powered device, you might dig up some evidence to help you in divorce court.
