Another day, another challenge.

Today’s blog post is solving the, “Meta Find Me” challenge within PicoCTF.

Let’s get started.

Clicking on the challenge we see:

OK, we need to find meta data inside of an image. Let’s see what the hints give us.

We need to answer the question of how location is stored in imaged. Look like Google will once again be our friend 🙂

After downloading the image, and doing a Google search of, “GPS info on photos” we’re presented with the following link.

Reading the link (which is from How-To-Geek) we learn that if we look at the properties of a image it will give the GPS coordinates.

OK, that’s a start.

While continuing reading the article we notice that with these type of images there’s an embedded EXIF data in the image.

Let’s try a Google search of “EXIF GPS decrypter” and see if we can view the embedded EXIF data for our image.

Doing that Google search we’re presented with the following link.

Going to that link, and uploading our image and click the “view EXIF” button we’re presented with the following:

Looking at the comment we see that part of the flag is present, we need to find the latitude and longitude. Luckily that’s presented above the comment.

Entering the flag we’ve acquired 70 points!
