Don't overthink it. Just string it !
I solved it using strings but, can this be solved by using binwalk then use hexeditor to fix the 'I Warned you.jpg'?
its 07601
binwalk, strings and grep
I learned a lot from this one. There should be an area with documentation for tools you can use and learn, in CTFLearn. Maybe there is and I don't know about it
Agreed. Never used binwalk before, though it looks like I should've.
use your grep power
