0beaeb0c17f05c53cb443b6f07d04c7674e47077d044595bf54648319fd1ab15

Flag Format: BUBT{Something}

Prerequisites

• <not sure what to put here> (experience I guess?)

Solution

We didn’t manage to solve during the contest time. One of our teammate bruteforced all the decoders available in the cyberchef 😂 That’s how we got introduced to ‘GOST (block cipher)’

Conclusion

• We should explore the cryptography used in various wars, like Enigma, Caesar, Vigenère, Lorenz, and ROT. It's fascinating to see how intelligent people were back then.
