Computer Security Watch – Nov 14, 2014 And Video Cards!

Video Cards: Part 2
Today’s Top Threat
Multiple Ichitaro Products CVE-2014-7247 Unspecified Remote Code Execution Vulnerability
This one may seem a bit strange, but with the recent vulnerability concerns with Microsoft Office it will make perfect sense. Ichitaro is a Japanese word processing software, much like Office. Currently it is the second most used office suite in Japan. So this having a vulnerability is a pretty big deal! Look for an update to come soon to the software.

Today’s Top Stories
Tracking Activity in the Chinese Mobile Underground
“We first lifted the veil on activities in the Chinese cybercriminal underground in 2012. Since then, we have continually reported about notable changes or activity found in this black market.
A few months ago, we noted that the Chinese underground has continued to grow, as the cost of connectivity and hardware continues to fall, and with more users with poor security precautions in place. In short, it’s a good time to be a cybercriminal in China.”

Further Research: Video Cards!
  A little bit ago we went over picking out a brand new video card, and we are going to do a bit of a follow up on picking the right card. When you look over a video card you can easily get intimidated by all of the information being shown to you. You will see things like cuda core, cpu, core clock, and memory, and I would like to explain these things a little bit better. Today I want to do a very broad over view of:

Graphic Cores – Compute Unified Device Architecture “CUDA” and Stream Processors
  It’s impossible to compare the NVidia CUDA cores vs ATI’s Stream Processors, they are not simply a 1 to 1 comparison. Each company built them on different technologies. A comparable ATI card has 2,000+ cores, where an Nvidia may only have 1,500+. The reason to look at the core numbers is to compare them to other models from the same manufacturer. A Nvidia card with a 800 CUDA core, will logically be slower than a card with 950 CUDA core. Given, it is not the only feature to considering when buying a card but what you can take away from this is simple, the more the merrier!
  The CUDA/Stream cores are like little processors that can be programmed to do a variety of things, like physics, texture processing and other advanced calculations. We are traditionally program to think, I can either get speed or I can get something pretty, so it may seem weird to think of it this way, but the faster your card, the better the graphics it can produce. It follows a logical path, more cores means more simultaneous calculations. More calculations mean that it’s processing the physics and image rendering quicker. The quicker it processes those, the faster you seem them resulting in a higher Frames Per Second, FPS.
