[ CSAW CTF Quals 2012 - Networking 100 ]

Well, i haven't got a blog since long ago as time is always not on my side.
Hopefully, this time round i will get to blog more often and not let the blog die.

This blog of mine will mainly focus on solving CTF challenges that I solved during or after the competition.

This time round, I was lucky to be invited to play in the recently concluded CSAW CTF qualifiers.
I was working on Networking 100 and i was given a pcap containing a telnet session.
You could grab a mirror copy of it here.

Well, my very first instinct was to use Wireshark to load the pcap.
Immediately, i could see the telnet session and Telnet by default do not encrypt any data sent over the connection. Thus, if we "Follow TCP Stream". We will be able to see the password as indicated in the image below.

That was pretty easy.

The key to this challenge is "welcome to 1969"


Cheers,
