Lost Key
Briefing:
Our agent on the ground noticed a USB key discarded outside The Yakoottees’ garage and he’s just uploaded the files for analysis. It’s probably nothing important; they just look like innocent jpg files. One looks corrupt, however. Can you take a look just to be sure we don’t miss anything?
Tip: The flag is in the file.
Hint:
Are you sure it’s a Jpeg?
How to Solve:
- Download the file and put it into a file checker, https://www.checkfiletype.com/.
- You can see the file is a PDF, rename the extension to
.pdf
and open the file to get the flag.
