Hass & Associates Online Reviews about ‘Here is how cyber warfare began — 50 years ago’

(CNN) — Computer hacking was once the realm of curious teenagers. It’s now the arena of government spies, professional thieves and soldiers of fortune.

Today, it’s all about the money. That’s why Chinese hackers broke into Lockheed Martin and stole the blueprints to the trillion-dollar F-35 fighter jet. It’s also why Russian hackers have sneaked into Western oil and gas companies for years.

The stakes are higher, too. In 2010, hackers slipped a “digital bomb” into the Nasdaq that nearly sabotaged the stock market. In 2012, Iran ruined 30,000 computers at Saudi oil producer Aramco.

And think of the immense (and yet undisclosed) damage from North Korea’s cyberattack on Sony Pictures last year. Computers were destroyed, executives’ embarrassing emails were exposed, and the entire movie studio was thrown into chaos.

It wasn’t always this way. Hacking actually has some pretty innocent and harmless beginnings.
