c0c0n XI DomeCTF Write-Up- CHINA- Team RedRaptor !!
Here’s our story towards the Second Position. In this write-up I will focus on how we captured CHINA from the day long challenging CTF race which gave us sleepless night organized by AppFabs and Kerala Police Cyberdome. :)
Our next country to capture was China.
We got a secret message. Can you get the message? Here it is
The secret message was a Base64 encoded string and so we might need to crack it to get our flag.
Let’s Go Decoding!!
First decoding>> No luck ! Base64 output
Second decoding>> Same result.. Yes it is encoded multiple times
Twelfth Attempt>> Success !! we got something we have seen somewhere, a hash value. :)
It was seen in some network devices but couldn’t recall which one. A simple googling got us with “juniper equivalent for Cisco 7 ”.
And yes that was it. Bingo!! We captured CHINA :D
Yeah!! We were the runners-up for the CTF challenge and congrats to the Gem and Sreelakshmy from RedX team for making it to the top.
A great loud thanks to my teammate Joseph Nygil and special thanks to Chetan, Sreehari and Rakesh S.
