Hi,
What will MA Do in this Case since the GC system is supposedly secure.
My guess:
MA would carefully check the cause, and if there's no possibility to blame you (i.e. if it is a clear hacking of the GC system) they'd present you with a non disclosure paper.
By a hard penalty clause you'd promise not to tell anybody about it, and having signed MA would fully compensate your loss.
This is how things like this are usually handled, and I'm quite sure the non disclosure waits on MA's desk because it was in use more then once already. Don't has to be GC fraud, could be users of exploits or similar, too ... Things MA doesn't want to see the light of the day.
Thoughts about GC hacking:
Guess it wouldn't be this hard - I'd attack a forum.
These often have vulnerable forum software - and I wouldn't start with EF or one of the other big ones, I'd attack a Soc forum. These are often placed by free hosters, and compromising such wouldn't be this difficult maybe.
A lot of ppl still use IE (or other older browsers), or have JS activated, or are still close to dementia when it comes to click "promising" links - and this way the forum hack would poison their PC.
Then a man-in-the-middle attack. As soon as the victim has authorized the log in, crash his entropia.exe, and take over the session, pretending to be the victim to the server. Bingo.
It's not this simple, I know. I don't want to give a how-to-do to wannabe hackers, I just want to point to a rather easy way to bypass even a system like the GC. Things similar to what I have described are happening every day, and they very often get regulated then in a way as I described above.
It all comes down to the one before the monitor - is she/ he able to use a computer in a responsible way? Since I often have to do with IT security issues I'd say most are not. By far the most people are constantly catching trojans, worms and virii, they click anything that isn't on the tree when counted to three, they are too lazy and penny-pinching when it comes to things like a good AV, a NAT-capable hardware router with firewall, even to installing and configuring a browser & EMail client that refuses to install all & anything.
Your EU account is perfectly safe if you keep the needed minimum of IT security level, even without gold card. But it takes some thoughts, a little effort, and very little money. Too much for many. For these a GC may add some little more security, but don't think it will help against a dedicated attack.
I know what I'm talking about, it's part of my job to participate in some sinister forums, too - I need to know what "they" are doing to help protecting my customers. "They" wouldn't bother using brute force attacks, much more easy to push kind of root kit to your machine ...
Don't try this at home, they are full of traps. But my machine is clean like a freshly changed baby's behind, for years now. I don't even have a personal firewall running on my computer - would be just another gate for attack.
Feel free to try to hack me - my IP is 127.0.0.1,
Have fun! ;-)))
