Challenge Description

My friend wants to convey something in his voice....

Flag format: xCTF{}

Attached files

• audio.wav

Solution

• Morse decoding the audio gives us R A B B I T H O L E ?

• So we try to extract the hidden file using stegseek

$ stegseek --crack Audio.wav 
StegSeek 0.6 - https://github.com/RickdeJager/StegSeek

[i] Found passphrase: "1qaz2wsx"       
[i] Original filename: "e.jpg".
[i] Extracting to "Audio.wav.out".

• We get a jpg file

• Running strings on the file gives us a string

• Enclosing the string in the flag format is the flag

FLAG
