WhatsApp messages are not deleted on iPhone and Android, says security expert

WhatsApp messages are not actually removed from the smartphone even if they are deleted or cleared from the device.This exposes the risk of hackers getting access to your personal data if they manage to sneak inside your device.According to Jonathan Zdziarski, a digital forensic scientist and security expert, more than one billion transcripts of user's chats remain active even if they are deleted by the user.

WhatsApp doesn't get rid of deleted messages

Despite WhatsApp not being involved in any manual action, the chat records are failing to be erased from the database, leaving behind traces to be recoveredAccording to a recent post by iOS researcher Jonathan Zdziarski, Facebook-owned popular instant messaging app WhatsApp doesn't fully get rid the chat conversations that have been deleted by users.In a recent encryption test conducted by the developer, it was found that the latest version of WhatsApp leaves traces of deleted chats.In fact, Zdziarski went on to say that deleting the app entirely is the only option to get rid of those deleted conversations.

Research shows deleted WhatsApp messages aren't actually deleted

Chat logs from WhatsApp linger on your phone even after you've deleted them, according to new research published by iOS expert Jonathan Zdziarski.Forensic traces of chats linger on the phone even after a user archives or deletes them, Zdziarski found, and could be accessed by someone with physical access to the device or by law enforcement issuing a warrant to Apple for iCloud backups.Although the data is deleted from the app, it is not overwritten in the SQLite library and therefore remains on the phone.
