Your iPhone Could Reveal Your Personal Secrets
Among the things that you take with you when you go out is your phone. And cellphones are combining to create a new security risk. On the one hand they are becoming more powerful, and more like computers. On the other, they are universally relied upon.
Some people rely too much on their phone and as a result, a stolen or lost phone can give unauthorized person access to private information or personal secrets that you may have on your phone. Jonathan Zdziarski–the man who discovered the kill switch on the iPhone– realesed a book title iPhone Forensics gives an insight into the surprising amount of personal information a smartphone can store or give away. Here is a list of all the possible secrets an unauthorized person can get through you iPhones.
- Past keyboard input - “Nearly everything typed into the iPhone’s keyboard is stored in a keyboard cache, which can linger even after deleted.” That will include user names, passwords and much more.
- Deleted images from the photo library, camera roll and web history can sometimes be recovered.
- Deleted address book entries, contacts, calendar events can also sometimes be recovered.
- “Exhaustive call history, beyond that displayed, is generally available.” The last 100 entries can usually be found, and deleted call records recovered.
- Map tile images, direction lookups and location coordinates from the Google Maps application. In effect, where you’ve been or may be planning to go.
- Deleted browser cache can usually be recovered, revealing the websites you’ve visited.
- Cached and deleted emails, SMS messages and other communications can be recovered, along with information on when they were sent and who to.
- “Deleted voicemail recordings often remain on the device.”
The rest of Jonathan Zdziarski’s book details the tools and techniques that will give you access to all those. Apart from an iPhone, all you need is some free software. Police forces already use records recovered from GPS units to solve crimes. Techniques like those in Zdziarski’s book look set to become a big part of the work of police and criminals alike.
Its a good thing not to have too much information on your iPhone, not if you want someone else knowing some of your deep dark secrets.
