[Shacknews] Valve announces Steam Guard security feature - Page 4

Thats why I used facebook as an example, the IP address and therefore general area of the PC should be enough no? Since this is steam we are talking about you'd probably also be able to add another security measure in such as the hardware having to match. I dunno, I do know that there are methods available for non-sandy bridge chipsets though (they may not be as secure but they'd stop 99% of philshers from getting the username/password).

No, the hash is isolated from all forms of hardware, the only way to get it is by reading the code off the chip itself. You set it up when you install all your hardware, and then that's it, it's integrated. You can't do anything else to find that code.

If you want to learn more about it from a security expert, listen to the podcast Security Now, where Steve Gibson explains exactly how it works. There is no ability to internet in to the code. It will only work on the computer that it originated from.

It works on the same principles as the football Paypal keys and the likes.

no no no, you don't know what I'm getting at. I'm saying that this can still be used on sandy bridge, its just that something else that is less secure but should still work very well could be integrated into steam for non-SB computers such as mine

In the end, all software solutions can be hacked, so the safest solution is hardware if you want 100%.

it would stop 99.9% of people and minimising it is what they should be aiming for, completely stopping it is next to impossible.

Because barely anyone has a static ip address. What happens every 2 weeks when my address changes....seriously man.

In all honesty, their is no need for any more account security. All you need is a little conman sense and if you are paranoid about it, authenticate your e-mail in the Steam settings. People can't actually expect Valve to fix stupid people.

Would this even prevent key loggers also?

This is what they are trying to prevent, a keylogger a is relatively easy way to get a username and password. This makes it so they need to authenticate that computer as well, which would bring up a message on the owners PC ect.

This is nice. Now we need one that works on AMD chips as well, because the feature is useless for me.


I imagine a simple MAC Address check would suffice.
