He claims that cloud backups are not encrypted and the intermediaries can obtain clear records of the conversations by simply applying for a court order.
‘Apple’s i Message has this problem and it’s just as bad, if not worse.
Zdziarski’s findings open up the fact after he scrutinized the disk images from an i Phone with the new version of the Whats App.
He found that the app retains and stores a forensic trace of the chat logs, even if you are deleting them this creates a ‘treasure trove’ for those who are mining for data.
However, this encryption is only applied when data is being transmitted, preventing carriers and other intermediaries from intercepting on your conversations while the data is travelling over the network.
But the findings from Zdziarski deals with what happens when the data reaches the phone, stored on the device and on the cloud as a backup.
Apple released its new operating system for i Phone and i Phone yesterday.However, there is one thing you should know for sure, and will be surprised.Whenever you clear (or delete) a message, or a batch of messages on Whats App, (be it an individual chat or a group message), they disappear from your screen immediately.But you should know that messages that are not seen on your screen, are actually still present on the smartphone, and are not permanently deleted by Whats App.A recent finding from an i OS researcher Jonathan Zdziarski reveals that Whats App retains all your messages that you have been deleting.
