Select the first frame, and you can quickly correlate the IP address with a MAC address and hostname as shown in Figure 5.įigure 5: Correlating hostname with IP and MAC address using NBNS traffic Open the pcap in Wireshark and filter on nbns.

This pcap is from a Windows host using an internal IP address at. The second pcap for this tutorial, host-and-user-ID-pcap-02.pcap, is available here. Fortunately, we can use NBNS traffic to identify hostnames for computers running Microsoft Windows or Apple hosts running MacOS.
We can easily correlate the MAC address and IP address for any frame with 1 as shown in Figure 4.įigure 4: Correlating the MAC address with the IP address from any frame Host Information from NBNS Trafficĭepending on how frequently a DHCP lease is renewed, you might not have DHCP traffic in your pcap. Based on the hostname, this device is likely an iPad, but we cannot confirm solely on the hostname. In this case, the hostname for 1 is Rogers-iPad and the MAC address is 7c:6d:62:d2:e3:4f. Client Identifier details should reveal the MAC address assigned to 1, and Host Name details should reveal a hostname.įigure 2: Expanding Bootstrap Protocol line from a DHCP requestįigure 3: Finding the MAC address and hostname in a DHCP request Expand the lines for Client Identifier and Host Name as indicated in Figure 3. Go to the frame details section and expand the line for Bootstrap Protocol (Request) as shown in Figure 2. Select one of the frames that shows DHCP Request in the info column.
Note: With Wireshark 3.0, you must use the search term dhcp instead of bootp.įigure 1: Filtering on DHCP traffic in Wireshark This filter should reveal the DHCP traffic. Open the pcap in Wireshark and filter on bootp as shown in Figure 1. This pcap is for an internal IP address at 1. The first pcap for this tutorial, host-and-user-ID-pcap-01.pcap, is available here. NBNS traffic is generated primarily by computers running Microsoft Windows or Apple hosts running MacOS. DHCP traffic can help identify hosts for almost any type of computer connected to your network. How do we find such host information using Wireshark? We filter on two types of activity: DHCP or NBNS.

If you have access to full packet capture of your network traffic, a pcap retrieved on an internal IP address should reveal an associated MAC address and hostname. In most cases, alerts for suspicious activity are based on IP addresses. Windows user account from Kerberos trafficĪny host generating traffic within your network should have three identifiers: a MAC address, an IP address, and a hostname.Device models and operating systems from HTTP traffic.Host information from NetBIOS Name Service (NBNS) traffic.It assumes you understand network traffic fundamentals and will use these pcaps of IPv4 traffic to cover retrieval of four types of data:

This tutorial offers tips on how to gather that pcap data using Wireshark, the widely used network protocol analysis tool. But what you likely want is unicast traffic from the phones, and that's where all of this comes into play.When a host is infected or otherwise compromised, security professionals need to quickly review packet captures (pcaps) of suspicious network traffic to identify affected hosts and users. In this case, you are probably using a network switch which provide filtering of unicast (at a minimum) data traffic by way of MAC addresses so you are only seeing the host s unicast traffic, and then subnet multicast and broadcast. Just setting promiscuous mode on an interface on a typical interface/typical network will usually not produce meaningful data as the infrastructure is filtering what data is sent where and has to be configured to provide it to a place where you can capture it. This doesn't have to be expensive, but it may be equipment you don't have and might need to procure.įor WiFi, you may need OSs and adapters that support monitor mode and promiscuous mode. This may require changing the network configuration, the network hardware, or both, to accommodate. For wired, you may need to force the phone's traffic onto a single network link and capture traffic from it through a tap, mirror port, etc. You may need special equipment in either case. Only then do I progress to OTA captures if the need arises. Really depends on the problem as to what you need in any event, I always start with wired captures of communications of wireless devices if at all possible to scope the problem. If you really need over the air (ota) capture of the devices, there is a setup page in the Wireshark wiki. Some setup instructions to get you started are here. If you can, focus on wired capture of the wifi devices as it is usually easier.
