Cyber attacks - NOT amateur radio

From my own limited experience, I know cyber attacks are a real threat.

According to the BBC the UK Foreign Secretary is to warn Russia that the UK will retaliate if the Russians are guilty of cyber attacks that threaten national security. I am sure most governments have a "dirty tricks" department. Some get caught. It is the nature of 21st century warfare.
