A recent network forensic examination of popular messaging service WhatsApp is offering new details on the data that can be collected from the app’s network from its new calling feature: such as phone numbers and phone call duration, and highlights areas for future research and study. The study was conducted at the University of New Haven’s Cyber Forensics Research & Education Group, and the results were outlined in a paper published in the scholarly journal, Digital Investigation. The research demonstrates the type of data that can be gathered through the forensic study of WhatsApp and provides a path for others to conduct additional studies into the network forensics of messaging apps. Decrypting the network traffic is not simple, the authors suggest, as both access to data on the device as well as the full network traffic is needed.
