Despite their latest deployments in safety, it seems that not everything is so regulated in WhatsApp when wanting to delete messages or conversations. This, after a security expert discovered that this content can be recovered.
According to 9to5 Mac, Jonathan Zdziarski was who found this flaw, which allows the chats both through our devices or through iCloud, thanks to backups.
The problem was included in the latest version of the application on iOS, where even though you have removed any messages, these leave a trace. The reason for this would be because WhatsApp does not overwrite the deleted conversations, in a security problem that can also be found in other messaging, such as iMessage services.
With respect to whether useful end-to-end encryption, the truth is that this method actually applies, but that does not mean that you apply to the data stored on our phones.
For this reason, Zdziarski points to anyone with expertise in computer science, you can access this information, in what is a stumble around security and privacy of which the application claims to have. For now, a solution is the disable the backup in iCloud, so have no fear that these data can be established by others.
