Search about DTMF

You do have to find the right DTMF decoder tool, and then manually spellchack the resulting flag. Fun, but easy

piece of cake

First I felt like it was impossible. But I solved it

Hint: DTMF

If You Got Numbers convert them from decimal to ASCII

One of the most interesting challenges on CTFlearn. Thank you, GreenGoblin30!

I have got the numbers but I am not sure about 24 hour clock..what kind of encoding is it? I tried t9 decoding but it did not work .Kindly help

same

try to get the sequence of these number from the wav file

try to get the sequence of these number from the wav file

try to get the sequence of these numbers from the wav file

Done :}

me too. I got the numbers. 24 hour clock means 1pm to 13:00. but what about 64 years old 10 month ago? what should i do more with these numbers. these numbers doesn't mean anything with multi-tap phone cypher (SMS). any hints?

I haven't done it yet, my first thought when I saw 64 was base64 so maybe it's that?

Edit: Nvm I just did it, I didn't end up using that clue at all

Can you get the correct file so we can correct this?

What if the user is deaf? I would not be able to solve this without some help as I am deaf

Guys read about dial tone and DTMF decoding, search online tools or use git hub tools to extract numbers from the the .wav file. Listen how numbers are being typed, its important. Then try to decode numbers. Thanks to that challenge I've learned about DTMF and how to it works. I've also learned how to write python script for decoding these numbers.

That was really cool and interesting, I've never done anything like that before

First I felt like it was impossible. But I solved it

WOW dtmf New Cipher CTF. Every one want to take this CTF. Good Job bro :{)

Thanks
