Lets download the zip and see whats up

Lets check out that html

hmmm lets look at the code…

I can also adjust the checkered image to see the text as well.

Changed the values from 184px to 1px

Looks like the flag isn’t here. Lets look at some other files that were in that zip.

Whats aes.js?

There is a lot of stuff in there but if you have a good eye you can spot the flag.

Another nice CTF. This one was pretty laid back went for over a weeks time.  Seemed to have a lot of Stego and crypto challenges pretty low on an type of reverse or forensics. Everything seems to have gone smoothly I didn’t notice any issues. Some members of Overflow Security were in and out of the challenges. Here are the write ups for the ones that I completed.
