I had this member sign up to my site yesterday, nothing suspicious at all. He uploaded what i thought was a ordinary picture, you could see the thumbnail in the gallery preview. but when you clicked on the thumbnail nothing shows up. This is where the fun started, i tried to go back to my homepage and my site went down, well not down but my ip addy was blocked by my host from my site for attempting to have 300 attempts in the space of a few seconds at getting into my cpanel. They quickly sorted it, so i thought nothing of it, but it did it again, just after i clicked on the same thumbnail. what it looks like it does, is when someone clicks on the thumbnail, its starts an attacking process off using the ip addy of the person that clicks on the picture. My host is keen on security so they have mods that protect your cpanel so soon blocks the attack.
Now i dont know anything about hacking, but to me this sounds a bit science fiction, but its the only thing that can explain it. Course i banned the member and got rid of all the uploaded pictures he put on, and its been fine ever since.
As anybody ever heard of this sort of thing before using a picture like this.
