Ever wondered how big ICMP errors can get? Well.. I got an answer for you in today's Packet Tuesday! https://youtube.com/watch?v=z9jk8Bbf4_o… #packetlife #pcaps #icmp #inpcapswetrust #packets #sec503

Today, I got some IPv6 Router Advertisements for you to dissect for Packet Tuesday. I hope you are having fun doing some IPv6 for a change :) https://www.youtube.com/watch?v=uRWpB_lYIZ8 #packetlife #ipv6 #sec503 #pcap #tcpdump #wireshark #packettuesday

All this talk of hex has me going a bit wacky #SEC503

Packet Tuesday is back after the holiday break. Watch me dissect a packet with IP options caught in the wild, not crafted :) https://www.youtube.com/watch?v=HldNL3SLLwM #packetlife #sec503 #ipv4 #ipoptions #pcaps

The next episode of Packet Tuesday just dropped. Learn about ICMP errors and how they lead to a recent buffer overflow vulnerability in FreeBSD’s implementation of the ping utility. #packettueday #ping #freebsd #sec503 #packetlive https://www.youtube.com/watch?v=Bgmfl17AQWA

Packet Tuesday Episode 4: TLS Client Hello. #tls #sec503 #packetlife https://i5c.us/0nGvkP https://isc.sans.edu/diary/29306

Episode 3 of Packet Tuesday is live. This week, it is all about the TCP Urgent flag. Trying to keep them a bit shorter in the future to not spent half an hour on one bit ;-) https://packettuesday.com

I hope everybody is enjoying these as much as I do. Thinking about moving on to some SSL stuff next, but also trying to keep them a bit shorter. Let me know if these work for you, or what I can improve. If I spent half an hour on a TCP flag… who knows how long the SSL Client Hello episode will get :)

And please let me know if I am making mistakes. I am not perfect and actually learn new things as I put these together. Well, I can always claim that I add intentional mistakes to increase “engagement.” :)
