Client is a leading law enforcement agency in India. Client has received a hint about a particular drug dealing case. The conversations about this deal were happening via WhatsApp messages. Unfortunately, all the messages were being deleted and there was no way to prove the crime. Recovering these deleted chat messages could prove to be important evidence to stop illegal activities.
The case was challenging in terms of technology and the process used. WhatsApp, as we all know has high end security built-in for all chat messages. The messages are end-to-end encrypted. Forensics on mobile applications that are secured with encryption require specialists to handle it.
As one of the leading Digital Forensics companies in India, ECS was approached to help recover some of the messages that were highly inaccessible in WhatsApp.
Here are the steps followed and the challenges faced by ECS to recover the deleted chat:
ECS’ task at hand was to first access this inaccessible device and then recover the deleted mobile chat which could be used by the law enforcement agency as evidence to prove a planned illegal activity.
Mobile devices are becoming more and more essential part of forensic evidence these days. Many pre-planned illegal activities have some or the other communication over mobile phones – either call, chat messages, videos, images etc. Mobile devices are also store houses of a person’s personal information and professional data. ECS helps with accurate and advanced mobile forensics by helping with the retrieval of trivial information that can help law enforcement agencies to prove a crime or an illegal activity. ECS follows a well-defined process for mobile forensics.
ECS analyzed the client’s requirements and developed a detailed plan to retrieve the information required. Mobile forensics requires the expertise of mobile technologies. We used Mobile forensics tools such as UFED Cellebrite, Mobile Edit, Oxygen Forensic. We also provided a final analysis report for the case being investigated.
With mobile forensics, ECS was able to help the law enforcement agency with the evidence they required for stopping an illegal activity. Our experts were able to successfully recover the deleted chat from WhatsApp.

In some cases, police may recover or identify deleted WhatsApp-related evidence through authorized forensic examination, depending on the device and available digital artifacts.
Sometimes relevant WhatsApp artifacts may remain available without a conventional backup, but recovery depends on the device, encryption, storage condition and other available evidence.
Authorized investigators may use mobile forensic techniques to acquire and analyze available device and WhatsApp artifacts to determine whether deleted evidence can be recovered.
A cyber cell or authorized forensic team may examine available WhatsApp artifacts to determine whether deleted or related evidence remains accessible.
Investigators may analyze WhatsApp and other digital evidence sources, but the availability of deleted message content depends on the evidence remaining on or associated with the device.
Forensic investigators may be able to recover or identify residual WhatsApp artifacts depending on the device, operating system, encryption and available evidence.
Recovery may be possible in some circumstances, but deletion does not guarantee recoverability and results depend on the device, storage and available backups or artifacts.
Investigators may examine available WhatsApp and device artifacts related to calls, but the availability of deleted call information varies by device and forensic evidence.
Deleting a WhatsApp message removes it from the normal user interface, but related artifacts or copies may sometimes remain elsewhere depending on the device and available data.
No. Recovery is not guaranteed because encryption, overwriting, device condition, application behavior and other factors can affect the availability of deleted evidence.
