Running Can

We are given a mp3 file

Strings

└─# strings runninground.mp3 | grep sctf
sctf{d1d_y0u_9wq

we got the first part of the flag from checking the strings in the mp3

Binwalk

└─# binwalk runninground.mp3

DECIMAL       HEXADECIMAL     DESCRIPTION
--------------------------------------------------------------------------------
0             0x0             EBML file, WebM

Interesting! There seems to be an image file hidden within the mp3 file

Lets extract it using binwalk --dd='.*' runninground.mp3
