Packet analysis

Using a Raspberry Pi to proxy, capture, and decrypt data from mobile and IoT devices

5 min read

Have you ever wondered what your “smart toaster” was sending back to the internet about you? Or how your WiFi dog food dispenser knows your schedule? Our engineer Tom did, but he didn’t have a great way to capture the network traffic sent by mobile and IoT devices. So he turned a Raspberry Pi into a access point/network proxy capable of capturing packets and decrypting SSL within CloudShark, and now you can too. Keep reading

Packet capture on VMware virtual machines using vmnet-sniffer

5 min read

One of the most powerful tools we use when testing CloudShark is a combination of VMware Workstation and the Vagrant API interface. With Vagrant, we can test every permutation of CloudShark via a barrage of automated testing. Along the way, we had to learn some of the lower level interfaces of these tools. We became aware of a vmnet-sniffer command that comes with VMware Workstation and VMware Fusion, which we use on our OS X workstations for development, and realized that it’s a great tool for capturing on virtual machines or in a cloud environment when used with CloudShark for analysis.
