Keep it Simple Stupid: KISS principle states that design simplicity should be a key goal and unnecessary complexity avoided (http://en.wikipedia.org/wiki/KISS_principle).
The K.I.S.S. principle also applies to information security attacks in many ways. The most recent example is something we picked up on this month. It is a very simple malicious code attack that is very simple, yet is very affective. Note: DNS redirectors are nothing new; this is simply another example of how we need to keep our eye on the ball to cover the most complex and simple threats today.
Like many the attack starts of as a simple spam run that requests users download a new ?Anti Phishing Toolbar? from Microsoft. In this particular case the attackers are going after Spanish speakers who, in particular bank, with Banamex.
The users are tempted to connect to a website to download the tool. The site, which was up and running at the time of this blog, was hosted in the United States on a free hosting provider website and was serving a filename called ?Microsoft_AntiPhishing.exe?. There was no exploit code on the site so users would be prompted to download and install the file. The files MD5 hash is 76d80aeff8248df387caa34b3389f52a, was written in Visual Basic, compiled with a Spanish version of Windows, and was poorly covered by anti-virus signatures (2/32 vendors recognized it).

Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
