Question

I have a sync app that doesn't work and the developer asked me to try and perform a sync with Wireshark capturing the data and send the Wireshark log to him.

I noticed that Wireshark saves sensitive data in the log, like the MAC address of both my devices involved in the sync process. Is there a built-in feature with which I can strip all this sensitive data out of the log I need to hand over to the developer? Any external tools?

Bonus question: Developer has a good reason to ask for this data, but he didn't tell me anything about the fact that the log would contain sensitive data. What should I do? Are this data really that important? Should have he warned me?

Explanation / Answer

Are you sure that the data in the capture is sensitive data? If it's the MAC address that you are worried about, I can assure you that it is not sensitive, and not useful at all to any potential attacker.
MAC addresses are not traceable nor are they used for any kind of authentication (besides WIFI whitelists, which would require the technician to actually be within range of your WIFI network).
Infact, in the normal run of things, the MAC address never leaves your local network (I.E. It never gets to the internet).

Similarly, local IP addresses will not go out to the internet, and will be changed by your router/modem.
