use binwalk [binwalk itself must be run as root i.e (--run-as=root), then extract the zip file, locate extracted file there you'll see "b.jpg", use strings ie "strings b.jpg", flag waits you. have a goodday :)

foremost

unrar et strings

dobre

still ez yea

Don't look at the comments if you do not want spoilers.

strings :>

Eat more oreos :)

too ez for being medium

This should have been in the easy section

Nice task binwalk,string and grep did it all for me

I found it easy. If you have done all the "EASY" forensics problems, this one should be a breeze

it very ez --> don't leave out the details

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?

at strings i've got only "This is not the flag you are looking for". Binwalk didn't find any hidden file.

binwalk finds a .rar hidden... i cant get it tho cuz mac lol
