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/…

To all the IT staff at #hospitals out there: do me (and more than that, yourself) a favor and put mandatory MFA on your VPNs *now*. If you think that's expensive there is something even more expensive in orders of magnitude: #ransomware guys using your VPN to encrypt you. #DFIR

Or to put it into another argument: A span port will show you what it will let you see and what you might have unknowingly configured, a TAP will show you what you want to see. Especially if you want to play around with physics layer staff, TAPs are the only way to go.

#Wireshark 4.2.2 has been released. If you're running versions 4.2.0 or 4.2.1 on Windows you'll have to download and install it by hand. Sorry about that. wireshark.org/docs/relnotes/…
