It is possible to trace deleted messages from WhatsApp, though it may be difficult. Forensic experts have developed techniques to recover deleted messages from the app’s servers and backup files. This is done using sophisticated software that can detect and analyze data stored in a device’s memory.
The technique used by forensic experts is called “data carving”, which involves recovering data from an unstructured source such as a hard drive or mobile phone. The carving process extracts data that has been “deleted”, but remains on the device in fragments. These fragments are then put back together like a puzzle to form a complete message or other piece of information.
Data carving can be used to recover deleted WhatsApp messages, provided that there is still trace evidence of them on the device. It is important to note that this technique only works if the deleted messages are still stored on the device, either in the app itself or in its backup files. If they have been completely wiped from memory, they cannot be recovered.
WhatsApp also has a feature called “delete for everyone” which allows users to delete messages sent to another user before they have read them. In this case, it is not possible to recover the deleted message as it is wiped from both devices and server logs instantly.
In addition, WhatsApp encrypts all communication between users so that messages cannot be intercepted by third parties while they are in transit. This provides an extra layer of security and privacy when using the messaging service, though it does make it more difficult for forensic experts to trace deleted messages.
Overall, it is possible for forensic experts to trace WhatsApp messages after deletion if there are traces of them left on the device or server logs. However, this process can be complicated and time consuming due to encryption and other security measures put in place by the app developers.
In conclusion, it is possible for forensic experts to trace deleted WhatsApp messages if there are traces of them left on the device or server logs; however this process can be difficult due to encryption and other security measures put in place by the app developers.
