basic binwalk and strings
it was easy just use binwalk and strings
For who doesn't understand binwalk, strings and grep like me.. try to make the jpeg as zip file (using .zip extension) then using online zip extractor(https://www.ezyzip.com/unzip-files-online.html), open the zip file.. there you can see folder & then select b.jpg.. then save the jpg and use cyberchef (Pro tip: Use strings as extractor).. You know to use cyberchef right?
I found it easy. If you have done all the "EASY" forensics problems, this one should be a breeze
foremost -i <image file> the extract rar then you will get image xxd <that image file> manually check flag
at strings i've got only "This is not the flag you are looking for". Binwalk didn't find any hidden file.
