Frens,
I could ramble a bit about what I found, since it was kind of interesting.
So I did not really want to click the link, i checked the creds passively. The site looked legit from the royal australian college etc. Then I did bother to do some setup to click the links and see what is up but the resources are down. So most likely a guy just found a way to upload to the server storing images and whatnot.
From what i gather when you opened the link it redirected you to another domain?
If that is the case it is plainly because the people that own the website have, for some reason, decided to have media served by a script. For example, if you go to the actual domain, get the dev tools up, and inspect an image, if you have a keen eye you might observe that it has an .aspx extension. If my theory is right then there exists, for some reason that is beyond me, a script for each image that runs each time you request an image. That means that if you can upload movies, or whatever is a file, you could upload such a script that would redirect each user to that "moneymaking" site.
Whatever. I cannot really test it or look at what code they are running because that is not really cool.
It smells like skid stuff, also the website might had been written by a drunk guy.
The only thing that i regret is that i did not see his moneymaking website.
Thanks for reading my blog post. Also if you want to replicate what the skid did, don't. It's quite illegal and it's not worth the hassle
