Who’s Behind Stuxnet? The Americans? The Israelis? – Security Watch.

The security research community continues to marvel at the sophistication of Stuxnet. In fact, there is a growing body of opinion that Stuxnet must have been developed with government sponsorship. Since 58% of identified infections seem to have occurred in Iran, the two obvious countries attracting speculation are the United States and Israel.

Previously, I’ve written about Stuxnet on August 14,  September 15, and September 17.

Aside from the extremely precise targeted nature of Stuxnet, what is striking is that it took advantage of four different 0-day or unknown vulnerabilities.

If this is not a wake-up call for the need for specialized 0-day malware defenses, I don’t know what is.
