We get 2 files in this challenge.
one is JPEG and other is WAV
So first thing I do in case of image is check EXIF info.
notice : XP Comment : aamirkhan
After playing aroud a bit with image I took the WAV file and put it through DeepSound in my windows VM.
Here we get a new file : word_doc.docx but it was password protected.
here i just tried the above XP COMMENT and it worked !
The word file we got was also password protected, so we extracted the hash using office2john and cracked the password with john
password : superstar
the contents of the file are not visible as they are white in color just
Ctrl+A
and copy and paste in notepad or change color.
