Shark??? in the ocean??? Ayo?????
We were given a pcap
file with little to no hints given. Naturally, we just looked filter for HTTP traffic but unfortunately, we did not find anything interesting
At this point, we looked at almost every protocol that were in the pcap file and we were not making any progress. Finding a needle in the haystack.
Flag: STANDCON22{W1R3SH4RK_EXP3RT?}
A teammate of ours had an idea to filter for 22{
via . The reason being was because that is the last 3 characters of STANDCON22{}
flag.
We kept on looking till we saw an interesting string, FGNAQPBA22{J1E3FU4EX_RKC3EG?}
. It looked like a flag but obfuscated!
Additional Information: Here's a good on detecting ROT13 /Base64 encryption.
As we were analysing the string, we realised that it has a shift value of 13, and so, we figured that it is a cipher.
We went to and we managed to get the flag!!!
