We’ve entered a new age of cyberwar (Fred Kaplan, Slate)
So the United States is hacking Russia’s power grid, just as Russia is hacking ours, in ways that are more aggressive than in the past, according to a front-page story in Sunday’s New York Times. But what does it all mean? Is this hacking really much different from what’s gone on for many years? Does it boost the chances of a cyber arms race or a cyberwar?
One thing is clear: Cyberspace is now seen by officers and officials as just another “domain” of warfare—along with air, land, sea, and space. But there’s something different and more dangerous about this domain: It takes place out of sight, its operations are so highly classified that only a few people know what’s going on there, and it creates an inherently hair-trigger situation, which could unleash war in lightning speed with no warning.
The Times reports that Donald Trump wasn’t even fully briefed on the hacking of Russia’s power grid, in part because officials feared that he might “countermand” the order—suggesting the hack was in place before they told Trump anything about it—and that he might tell foreign officials about it, carelessly or otherwise. Whatever the reason, Trump wasn’t fully briefed because he didn’t have to be.
