Solution
Running strings on the jpg provided, we see there are few files embedded in it.
Use Binwalk to extract(
binwalk -e <file-name>
), we get 2 more images which contain more embedded filesgreenpill.jpg
redpill.jpg
Extracting greenpill gives us nothing but a troll image
Extracting redpill.jpg gives us a wav file and a encrypted zip file
Morse decode wav using this tool gives us
T H E P A S S W O R D I S T H E H O V E R C R A F T O F M O R P H E U S
Googling
THE HOVER CRAFT OF MORPHEUS
gives usnebuchadnezzar
Using
nebuchadnezzar
as password for the zip file, we get a wav file nameddeep_secret.wav
The name of the file is a hint: deep
We can use deepsound to extract flag file
It gives us a text file which contains the flag
