misp-wireshark is a Lua plugin intended to help analysts extract data from Wireshark and convert it into the MISP Core format

1. Go to Tools located in Wireshark's top bar and click on MISP: Export to MISP format
2. Enter the export options to configure the behavior of the exporter
   • 
   • Main filter: Fill this field to filter the exported data. Essentially, it will just be a copy/paste from the global filter in the interface. (This cannot be done automatically because of this)
   • Include HTTP payload: Should the payloads sent via HTTP be included as a file in the output
   • Export path: The location where the exported file should be saved when clicking on Save to file
   • Tags: Optional tags can be attached to some MISP attributes.
3. Copy or save in a file the data to be imported in MISP
   • 
4. Import in MISP
   • 

Command-line options are the same parameters as in the user interface:

• filters: The filter expression to be applied
• include_payload: Should potentials payload be also exported. Accept y or n
• export_path: The folder under which the json should be saved. If not supplied, default to stdout
• tags: Optional tags to be attached to some MISP attributes

Example

tshark \
    -r ~/Downloads/capture.cap \
    -X lua_script:/home/john/.local/lib/wireshark/plugins/misp-wireshark/misp-wireshark.lua \
    -X lua_script1:filters="ip.addr == 127.0.0.1" \
    -X lua_script1:include_payload=n \
    -X lua_script1:tags="tlp1,tlp2" \
    frame.number == 0

Note: As we did not supply an export path, the result is printed on stdout. However, to avoid mixing both the plugin output and tshark output, we provide a filter to tshark that will filter out every packets. However, this filter is not used by the plugin. Only the filter provided via -X lua_script1:filters is used.

Based on the example above, frame.number == 0 is only used to prevent the output of tshark while ip.addr == 127.0.0.1 is actually used by the plugin

On linux, clone the repository in wireshark's plugin location folder
