Cryptology Attacks: What’s New
A new attack on RSA called Simple Branch Prediction Analysis promises to reveal “almost all of the secret key bits” by executing a parallel spy process that only needs to watch a single execution of the RSA private key. Some more technical details show it to be a sophisticated, dangerous attack:
Namely, in the context of simple side-channel attacks, it is widely believed that equally balancing the operations after branches is a secure countermeasure against such simple attacks. Unfortunately, this is not true, as even such “balanced branch” implementations can be completely broken by our SBPA attacks. Moreover, despite sophisticated hardware-assisted partitioning methods such as memory protection, sandboxing or even virtualization, SBPA attacks empower an unprivileged process to successfully attack other processes running in parallel on the same processor.
If that weren’t bad enough, a rootkit now can be persisted in your PCI device. A paper called Implementing and Detecting a PCI Rootkit details how PCI cards execute bios code which can be flashed from the windows software if the user is running as an administrator. Combined with a remote exploit, this could lead to a remote rootkit injection. Also, given that PCI BIOS software is not verified in any way, the rootkit would difficult to detect.
Medieval Total War 2: Text Corruption Graphics Bug
Playing a hot new video game should not produce this result:
Apparently, players with ATI 1900 and 1950 graphics cards are experience text corruption in-game. The solution quite simple–just follow these steps:
- Open the ATI Catalyst control center
- Turn off ATI A.I. Technology
As you can see the text are not like it is supposed to be, he also had that text-problem with the demo, but he could play the historical battless then. But because of some problem he cant start the campaign and it just jumps back to the menu, I do not know if that have something to do with the text-problem.
He changed a little bit in the descr_strat.txt -file, but that was only the timescale, show date_as_ and the 17 playable factions playable and it didn’t work when he edited them back to the normal settings either.
This is the specs:
har: ATI Radeon X1900XTX 512MB
4096 MB DDR Corsair
AMD FX-60 2.6 GHz dual core
Soundblasters – Audigy SE
This answers questions like the above. Have fun!
Dog + Cat = Cog/Dat?
Yahoo news suggests that a cat who mated with a dog produced viable offspring:
This reminds me of how Humans and Neanderthals interbred. Prepare for super cats.
