John and Jack have become more security aware after falling prey to private message leak and credit card number theft. So, they decided to switch to a new VoIP service which provides SIP over TLS for signalling security and SRTP for the media stream security. However, their VoIP servers are using a publicly available key pair which allows almost anyone with the corresponding private key to decrypt the traffic and eavesdrop. A traffic capture of their exchange is provided.
Objective: Your task is to retrieve the flag from the exchanged messages.

Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email firstname.lastname@example.org clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
