Morse Code

1 minute to read

We are given this sequence of . and -:

-.-. - ..-. .-.. . .- .-. -. ... .- -- ..- . .-.. -- --- .-. ... . .. ... -.-. --- --- .-.. -... -.-- - .... . .-- .- -.-- .. .-.. .. -.- . -.-. .... . . ...

As the title of the challenge suggests, it is Morse code. Hence, we must decode the sequence.

We can do it manually: -.-. is C, - is T, ..-. is F… Or we can use an online decoder like morsedecoder.com:

Morse code flag

And we get this message:

CTFLEARNSAMUELMORSEISCOOLBYTHEWAYILIKECHEES

So the flag is:

CTFlearn{SAMUELMORSEISCOOLBYTHEWAYILIKECHEES}
