Stuxnet is a type of Malware that seems to be directed at Siemens Corporation. Not many people are writing about this, for some reason. The writing and press are focussed on the fact that the majority of attacks and reported incidents seem to be in Iran. And also, that this new form of Malware is very dangerous. It is. Malware is a type of computer virus that masquerades as useful software. It slips by Antivirus programs , usually as an update , patch or fix. There are different kinds of Malware. And there are different vectors. The worst kind, in my view - is rootkit. These are viruses that try to get administrator, or 'root' on your machine. And the worst vector, is when they replace a driver or protocol. I had a virus damage the TCP protcol once, and the only thing I could do, to fix it - was to uninstall the OS on the machine, and reinstall anew. In fact, that is what I would recommend. If you are hit with a very bad virus, and you've run scanners to delete it. B
