Whatsapp Doesn’t Delete Messages When You Kill A Conversation And There’s Nothing You Can Do About It


WhatsApp is currently used by over a billion people around the globe.

The app generates huge amounts of information from the various chats, photos and voice calls that people share every day.

But even after deleting a conversation, the app retains information relating to the chat log in the depths of its code. That’s according to a blog post published yesterday from iOS researcher Jonathan Zdziarski.

He found what he calls “forensic artifacts” when he dug into the application using specialist tools.

And he goes so far as to suggest that if someone had the necessary tools, knew what they were doing and could get physical access to your device, they could pull out your information from deleted messages.

“When a record is deleted, it is simply added to a “free list”, but free records do not get overwritten until later on when the database needs the extra storage (usually after many more records are created),” he explains in the informative blog post.

Unfortunately, Zdziarski points out there’s no way to truly delete the information – unless you completely remove the Whatsapp application from your phone.

The Facebook owned chat app has made a big point about privacy in the past and recently introduced end to end encryption.

This makes your messages much, much harder to crack from the outside and Zdziarski concurs. He says someone would physically have to get hold of your device to be able to pull the forensic data from it.
