Description:
Kyv wcrx zj trgklivu_kyv_wcrx
Hint:
Step it up
The hint is the same as the flag from last time. Therefore, the cipher used to encode the flag is probably the Caesar cipher (again). Decoding this ciphertext when n = 9
gives the message The flag is captured_the_flag
.
Alternatively, instead of solving the challenge the boring way, you might have noticed that Kyv wcrx zj
looks a lot like The flag is
. Making the necessary substitutions, you would have gotten The flag is *a*t**e*_the_flag
. Then, you could have searched /usr/share/dict/words
with grep:
[!] sudo grep --ignore-case "^.a.t..e.$" /usr/share/dict/words

Fun fact: the problem title is "Caesar Cipher" with n = 25
