Please note that this article is intended for advanced users who have a strong grasp of network protocols and tools.
IP protocol model.
IP layers and how they contribute to network communication.
In network traffic analysis, layers 3 and 4 are crucial, dealing with transport and network layers.
Upon observing a captured WhatsApp network traffic sample, you can notice TCP and UDP packets being exchanged between clients and servers.
Capturing Network Traffic
To capture and analyze WhatsApp network traffic, we recommend using tools like Wireshark Network Protocol Analyzer or Tcpdump.
Network Traffic Decode
Decoding WhatsApp network traffic requires identifying the conversation ID, hidden in the first message packet.
Understanding WhatsApp Protocol
Analyzing WhatsApp network traffic involves getting familiarized with the protocol used by WhatsApp.
Identifying WhatsApp Data Packets
Upon observing a captured WhatsApp network sample, identify the distinctive characteristics and pattern of WhatsApp data packets.
Encryption in WhatsApp Network Traffic
In encrypted WhatsApp traffic, the focus is on packet traffic at the network interface.
Protocol Analysis and Conclusion
WhatsApp's extensive use of TCP and UDP ports for communication results in the production of vast network traffic.
Understanding WhatsApp network traffic patterns, UDP and TCP protocol utilization, and encryption will offer a comprehensive insight for developers, penetration testers, and security researchers who work with complex communication system technologies.
