 Hey, what's up everybody? My name is John Hammond. I want to bring to you one more video of Google's capture the flag CTF challenges video write-ups and solutions stuff like that So here we are again. I want to show you this Inrecorded conversation challenge IRC we're assuming it's operating under IRC and Again, it's IRC dot pcap. Can you find a flag at really really small point value a lot of people solved it Not a difficult challenge very very supposed to be easy like Google literally says this is easy in their front page So you can download the pcap and that's kind of what I did in my terminal. I'll hop on over there To in recorded conversation and you can see it's just this pcap. That's all I really needed. I ran strings on it and It's in plain text at least a lot of it is because it's IRC so you can just peruse through here and What I did is I actually ended up grepping for the CTF like the flag format CTF I look through here and Since it's all on the channel of the IRC channel CTF You were able to see anything within that that channel and that message So if you read through the conversations, you can say some people are saying I think major All right, seriously, I guess given the leaks. It is a flag. Don't you think maybe It but it's plain text. So I guess five eyes will get this flag. We'll get this flag before anyone else and you can see them So let's do it as a group I guess Yeah, so different people I guess in the in the message Start to speak or type in different parts of the flag. So you can see it being built here CTF Some underscore leaks underscore are underscore good underscore leaks underscore Some flags are good leaks some some leaks are good leaks and that was the flag Again, I'm not gonna build something it will put this all together for us But that it was literally just that easy was literally running strings on it hunting forward a little bit I didn't even open up wire shark. I just tried to look for strings and found this CTF flag format And then I just put that I built that wrote out CTF some links are good leaks and I put that together Again, not that difficult. That's why so many people solved it and it was only were 25 points but a good one to have under your belt and Another solution to the Google capture flag CTF so thanks again for watching guys Hope you enjoyed this just a simple solution and want to demonstrate it to you and I'll see you later
