A picture is worth 1000 words (25)
forensics - Louisa County High School
Challenge description:
Download the attached image. Don’t get lost in all those pixels. Find the flag in all those details.
Download file: apictureisworth1kwords.jpg
Solution
Running strings on the image reveals the flag. We can run it with the -n flag to say we only want strings above 8 characters. (This is a pretty safe assumption as the “CTF{}” format is 5 characters, and we can always remove our threshold.)
$ strings apictureisworth1kwords.jpg -n 8
