Report: Israel, US Behind Iranian Spying Virus

A U.S. cyber security expert says it is "pretty likely" the United States and Israel are behind a sophisticated computer virus that appears to have been used to gather intelligence about Iran's nuclear program.

Tofino Security chief technology officer Eric Byres said there are only a few countries in the world with the resources to develop something as advanced as the so-called Flame virus.

The Washington Post newspaper reports Israeli and U.S. security agencies used Flame to collect information about Iran's preparation for a cyber attack aimed at slowing its nuclear program.

Byres says the virus can be used in a variety of ways.
