How ECS Helped Retrieve Deleted WhatsApp Chat Messages For a Law Enforcement Agency?

Case Overview:

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.

Case Challenges:

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:

  • Our experts visited the location of the crime and collected the mobile phone with COC (Chain of Custody)
  • The mobile phone was then submitted for forensics purpose.
  • The condition of the phone was not suitable for immediate action:
    • It was Jammed (in flight mode)
    • It was Network Jammed (Faraday Bag)
    • Disconnected from the network

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.
