$s | Add-PefMessageProvider -Provider “C:\input\path\spec\Input.etl” $s = New-PefTraceSession -Path “C:\output\path\spec\OutFile.Cap” -SaveOnStop A short, simple script to do this might look like: Or you can convert to PCAP using PowerShell (of course you can). If you do need another packet analysis tool, it's easy to a File / Save As / Export, and save as a PCAP file that Wireshark, tcpdump, SNORT, ngrep, standard python or perl calls, or any other standard tool can read natively. Message Analyzer has a surprisingly nice interface and some decent packet parsing, you might be able to wrap up your analysis just in this tool (see below). Next, open the file (which is in Microsoft's ETL format) in Microsoft's Message Analyzer app - which you can install on your workstation rather than the server we ran the capture on ( ). If this is a pentest, a standard copy might still work (remember, we're on a Microsoft server), but if you need netcat type function to exfiltrate your capture, take a look at PowerCat (which is a netcat port in PowerShell). If this is a capture for standard sysadmin work, you can simply copy the capture over to your workstation and proceed on with analysis. If all you have is a metasploit shell, netsh trace works great! The cool thing about this is that it doesn't need a terminal session (with a GUI, cursor keys and so on). Tracing session was successfully stopped. "C:\Users\Administrator\AppData\Local\Temp\NetTraces\NetTrace.cab".įile location = C:\Users\Administrator\AppData\Local\Temp\NetTraces\NetTrace.etl The trace file and additional troubleshooting information have been compiled as When you are done capturing data, it's time to stop it: Trace File: C:\Users\Administrator\AppData\Local\Temp\NetTraces\NetTrace In a pentest you would likely specify an output file that isn't in the users' directory.Ĭ:\>netsh trace start capture=yes IPv4.Address=192.168.122.2 Note that you need admin rights to run this, the same as any capture tool. You could also add Protocol=TCP or UDP and so on.įull syntax and notes for netsh trace can be found here: įor instance, the following session shows me capturing an issue with a firewall that I'm working on. ' netsh trace start capture=yes Ethernet.Type=IPv4 IPv4.Address=157.59.136.1' One of the examples in this output shows you how t o e.g. We'll need to filter the capture, usually to a specific host IP, protocol or similar. Of course, in most cases, tracing everything on any production box is not advisable - especially if it's your main Exchange, SQL or Oracle server. Show - List interfaces, providers and tracing state. Type "netsh trace help" on any Windows 7 Windows Server 2008 or newer box, and you'll see the following:Ĭonvert - Converts a trace file to an HTML report.Ĭorrelate - Normalizes or filters a trace file to a new output file. And yes, it does exactly what it sounds like it does. Well, as they say in networking (and security as well), there's always another way, and this is that way. Please follow the instructions you find on the download pages.įor further help, try to find current instructions on Google.Have you ever been on a pentest, or troubleshooting a customer issue, and the "next step" was to capture packets on a Windows host? Then you find that installing winpcap or wireshark was simply out of scope or otherwise not allowed on that SQL, Exchange, Oracle or other host? It used to be that this is when we'd recommend installing Microsoft's Netmon packet capture utility, but even then lots of IT managers would hesitate about using the "install" word in association with a critical server. If you want to install Wireshark under Windows 8, please read also the following instructions.ĭisclaimer: We cannot support you with your Wireshark installation. To start capturing click on the "Start" button below the interfaces. Select this box to read packets on this interface. To the left of each Interface, you will find a checkbox. The Dialog to select an Interface also looks a little different on the Windows version of Wireshark: A window will open, in which you have to enter the characters "cmd" (without the quotes). You can do this by hitting the keys "Windows" "R". To enter the command "ping" on Windows, you will have to open a command line. You can find instructions how to install Wireshark on Mac OSX Mavericks here. You will find further instructions how to tackle this here. A better solution would be to add wireshark to a different group. On Linux you have to run Wireshark as root (sudo wireshark). Please see also the hints below the video. You can download Wireshark here for free. This tutorial will shortly introduce the sniffer Wireshark.
