Decrypt the wifi traffic (you need the network key for this since wifi itself is encrypted (WEP, WPA, WPA2 etc).Monitor in promiscous mode on the same wifi channel as the network.You can try viewing the network traffic to find passwords for these services, but it is very involved… That should prevent the mail being sent in plain text across the network, however email is inherently insecure as a service (it bounces from mail server to mail server with to & from addresses visible) so the kids may be better off using iMessage or another chat service that has some level of encryption / privacy. If they are using an email client like Apple Mail check the settings again for each mail server, there are options to only use the specific server, and only use secure protocols (SSL,TLS…). Explain to the kids why the 'green lock' in the address bar (indicates https) is important for reading email or any other 'private' data.ĭo the same with search engines (so their searches may be 'invisible' to the local network). Bookmark the https url for the child, and remove any http urls for the same site so they are less likely to use http by accident. When logged in does the website remain on https, if it goes to http instead the email content could be visible on that network. Some providers will only allow login via https which is secure, http is not secure, these can usually be 'forced' with account settings. If it is via webmail in the browser (or a 'browser based' app) look for account setting to only use https. Look at the devices - how are they accessing the email?

You can 'live boot' the Mac from a Kali USB stick if you don't want to install it but it is another few hundred things to learn ! had some wifi & wireshark tutorials that will be going out of date, but possibly relevant to a newbie 🙂 They have all the correct tools built in with many tutorials all over the net. Kali Linux or another 'penetration testing' Linux distro.

The Mac OS isn't really designed for this & I think you would be better off selecting the right tool for the job, e.g. It all sounds a little dubious, but not necessarily illegal provided you own the devices, network & everyone using the network knows this is happening too. There are systems in place that prevent you seeing passwords in plain text (like https which should be used for any sensitive data nowadays). I’m confident that I’ll still forget all about this post next time I try to show a University Computer Engineering class how many packets it takes to load the Facebook home page.The ones used to connect to the network? Or ones sent over the wifi to services like iCloud or other websites?īoth need a different approach & there is every possibility you cannot find them without having to 'intervene' on the clients. Note: you also need to restart Wireshark after enabling monitor mode before the 802.11 options will show up in the Link-layer header drop down option. I keep forgetting the need to restart Wireshark for the Link-layer options to change #facepalm. In comparison to capturing 802.11 frames in monitor mode: Now I can see Ethernet, IP, and TCP/UDP headers again:

Close it entirely, reopen it and voila:Įthernet is back! Also, the 802.11 options have disappeared because we’re no longer in monitor mode. I spent half an hour the other day scratching my head, when the trick is simply to restart Wireshark. I can’t believe this still trips me up every few months. I could’ve sworn that’s what it is set to by default after install… Then just set the Link-layer header back to Ethernet, just like your other interfaces:Įxcept “Ethernet” isn’t an option. Simple enough – turn it off in the interface settings (Find this button on the Main toolbar to access the menu, then scroll to the right to find the Monitor mode drop down and make sure your Wi-Fi interface has this disabled): I might be troubleshooting an issue and am using my Mac as the client trying to recreate the issue – so I don’t need monitor mode for that. On occasion, I actually use Wireshark to inspect higher level traffic – I want to see the IP addresses and TCP/UDP ports etc. I want to see the Radiotap and 802.11 headers. On my Mac, I use Wireshark primarily to capture Wi-Fi traffic, in monitor mode. This is one of those quick posts aiming to save me and (maybe you) some time the next time I forget this.
