[ HackYou CTF 2012 : Wikitap - EpikArc ]
Initially, i thought this could be a more forensics type of challenges. It turned out to be more of Network Forensics.
Mister You is willing to hire someone who can repeat his investigation.
Arc starts from here
The above link will give you a PCAP file.
Find the secret link in this conversation.
After analysing the the .pcap file for a while using Wireshark, it seems that the conversation is via HTTP POST.
So what i did was use the in-built filter in Wireshark to search for all the conversation in the .pcap file like the image shown below.
Then we find the following message.
As we can see the key to this particular challenge is "tinyurl.com/8pdox5a"
P.S: Going to the above link will give us the file for the Mystery Challenge. :P
Cheers,
Jacob Soo
