If there is any plain-HTTP traffic, you should see it too. You should now be able to see the traffic that was encrypted due to WPA2. Here you should enable the Enable Decryption checkbox for this, and enter your PSK clicking New, selecting wpa-pwd if you wish to enter the PSK in plaintext, and wpa-psk if you want to get the 256bit key passphrase. So, once you have the key for the encrypted network, it's just a matter of entering it in the configuration for Wireshark, so it decrypts before processing:Įdit -> Preferences -> Protocols -> IEEE 802.11

The sniffer would try to use one of the cracking methods to get the key.

If the WiFi network was open (as in, no encryption whatsoever), then you could simply 'hear' with the sniffer in monitor/promiscuous mode.Īlas, the WiFi network is encrypted, so, you usually would need first to monitor the traffic to crack that encryption (WEP or WPA2, the latter being the de facto standard this days and the former being absolutely useless, both are vulnerable). I guess you have 2 WiFi devices, lets call 'host' the legitimate network device connected to the AP/Router and 'sniffer' the one trying to capture the traffic. After your comments and update, I will try to answer, even though I'm still not sure I'm getting the question right. Perhaps I am missing something in my understanding of the data flow here?. So I would consider it possible I might be able to decrypt the radio packets between the target client and the AP, given the correct wireless passphrase (which again, I have). However, if I can see the radio traffic, I would expect to see all of the radio traffic, which would thusly contain all of the IP, even if it were encrypted.

There was a warning that some network cards would disassociate during monitor mode, which does make sense. This size is generally good enough, but to change it, click the Capture menu, choose Options, and adjust the Buffer size value accordingly. WireShark will continue capturing and displaying packets until the capture buffer fills up. Then I switched to monitor mode for that interface (see screenshot #3), and all I could see was radio traffic, not the IP within that radio traffic. To start the packet capturing process, click the Capture menu and choose Start. I was also monitoring in 'ethernet' mode. (This makes sense, even though I was in promiscuous mode, the traffic was between the AP (access point), and the target wireless client.) This made sense, since I was monitoring the local interface, and the traffic from the target device wasn't flowing through my interface on the macbook. I was able to detect network traffic from my local computer to the URL in question, but when viewing the same URL from a different device, I was not able to see that device's traffic.

Update for context and more information for I started this process, I used promiscuous mode on the en0 interface (wireless) on a macbook air.

If this is the case, is there software to decrypt the data after it has been recorded? If I need the passphrase, I have it (given that this is my lab network). What settings am I missing, or do I need to decode the WPA2 passphrase to view the data? I am also able to see and capture 802.11 packets using monitor mode, but I cannot see their content. I have wireshark configured properly to capture on the wireless interface. I've seen this in action (ala firesheep) on a wired network. I'd like to demonstrate that unencrypted (non-HTTPS) network traffic on a wifi network can be viewed by other wireless devices. It was precisely designed for this purpose, create a network capture from a single process (and its children) without leaking other traffic.I'm attempting to replicate a 'wifi cafe' setup in a home lab environment. Capture from either end of the veth interface and start your process within the network namespace.įor the latter approach, I wrote some scripts to automate it, it can be found at.

On Linux, create an isolated network namespace and use a virtual Ethernet (veth) pair to connect the new network namespace with the main network namespace.

Run a program in a virtual machine (VM) and capture traffic from within the VM, or from the bridge attached to the outside of the VM.

If you know that an application contacts certain IP addresses or ports, you could specify a capture filter such as udp port 53 or host.

For established TCP sockets, this information could potentially be looked up on-the-fly, but there is no way to express a capture filter to limit filtering to a single process. Arbitrary packets are typically not associated with a process.
