It is harder to defend a computer than to attack it.

The question posed by Yossarian in 'Catch-22,' ... is one of the great questions of modern times: Is this huge industrial military that we've constructed, has it become more deadly and powerful than the cause for which is was constructed?

These problems have been here so long that the only way I’ve been able to function at all is by learning to ignore them. Else I would be in a constant state of panic, unable to think or act constructively.

Today the most serious computer predators are funded by rich criminal syndicates and even nation-states, and their goals are far more ambitious. Cyberattacks were launched at digital networks in Estonia by ethnic Russian protesters in 2007 and in Georgia before Russia attacked that country in 2008; and someone, probably Israel or the United States (or both), successfully loosed a worm called Stuxnet in 2010 to sabotage computer-controlled uranium centrifuges inside Iran’s secretive nuclear program.

Instead of being assembled by genes, the worm was assembled by “memes,” a word coined by British scientist and polemicist Richard Dawkins in his 1976 book, The Selfish Gene. Memes are original ideas. Dawkins argued that they play the same role in cultural evolution as genes play in biology, getting passed along from person to person, surviving and adapting as they move.

By some estimates, there are 250 hacker groups in China that are tolerated and may even be encouraged by the government to enter and disrupt computer networks,” said the 2008 U.S.–China Security Review. “The Chinese government closely monitors Internet activities and is likely aware of the hackers’ activities. While the exact number may never be known, these estimates suggest that the Chinese government devotes a tremendous amount of human resources to cyber activity for government purposes. Many individuals are being trained in cyber operations at Chinese military academies, which does fit with the Chinese military’s overall strategy.
