One of the cool things about the computing industry is that many of its pioneers are still around to share their knowledge and stories. I'm beyond excited that Vint Cerf is going to speak at SharkFest again.

I recently updated the #UltimatePCAP and added some mail protocols: IMAP, POP3, SMTP, all in plain text, STARTTLS and implicit TLS. Go ahead and analyse it by yourself. ;) #Wireshark
This is it: The Ultimate PCAP. A single downloadable #pcap with more than 50 network protocols! Use it as your single #Wireshark sample file. weberblog.net/the-ultimate-p…

It pops up now and then: Why should you not run #Wireshark as Administrator/root. There are quite a few reasons for that, but a very good discussion about this topic has been written quite a while ago by @PacketJay and I just wanted to bring it up again: blog.packet-foo.com/2018/09/…

A security backdoor was recently discovered in liblzma 5.6.0 and 5.6.1. #Wireshark's Windows and macOS installers ship with liblzma, but not with those versions.
