Wireshark 3.0 Released

Wireshark

Recently, Wireshark dropped a major release which adds a few cool features (some new and some old). However outside of the new features, there is one major under the hood change this feature introduces. WireShark v3 for Windows now ships with Npcap as opposed to Winpcap that we have been used forever now. Npcap is actually part of the NMAP project which while Npcap is build of Winpcap Npcap gets a little more love in regards to up updates and being actively worked on. A while back I did a look at how Winpcap interacts with the NIC cards and captures packets, Even though Npcap is based off Winpcap I am curious to see if that underlying interaction has changed (more to come on that, or I’ll just update this blog post later on with my findings)

A few other features:

  • IP Mapping has returned
  • Monitor mode support for Windows wireless analysis. This is a huge one in my book, this functionality was brought over from the Npcap change.
  • A few other random tidbit, bootp dissector is getting renamed to dhcp. Similar to SSL getting renamed to TLS.
  • ciscodump now supports a proxy connection, I am going to need to check this out, as ciscodump utilizes the Cisco EPC capability. Which apparently I haven’t got to kick the tires on just yet. So, I think I am late to the game on this one, but proxy supports make this easier for some environments.
  • There are quite a bit more changes, many new protocols were added and well as even protocols were updated.

For the sake of brevity I don’t to cover everything, just a few of the pieces are find more interesting and useful.
