Iran says it has developed tools that can defend against the well-known cyber attack tool Flame, the BBC reports.
The country is believed to have been hit hard by the malicious programme which infiltrates networks in order to steal sensitive data.

Iran says its home-grown defence could both spot when Flame is present and clean up infected computers.
