World Cyber Cold War Heats Up

By Peter Griffiths

LONDON (Reuters) - A "cyber cold war" waged over the world's computers threatens to become one of the biggest threats to security in the next decade, according to a report published on Thursday.

About 120 countries are developing ways to use the Internet as a weapon to target financial markets, government computer systems and utilities, Internet security company McAfee said in an annual report.

Intelligence agencies already routinely test other states' networks looking for weaknesses and their techniques are growing more sophisticated every year, it said.

Governments must urgently shore up their defenses against industrial espionage and attacks on infrastructure.
