An interesting though scary article in WIRED indicates how Russian Hackers used the Ukraine to test out some very invasive hacking methods and crippling the country’s services in the process, an excerpt below
From the beginning, one of this war’s major fronts has been digital. Ahead of Ukraine’s post-revolution 2014 elections, a pro-Russian group calling itself CyberBerkut—an entity with links to the Kremlin hackers who later breached Democratic targets in America’s 2016 presidential election—rigged the website of the country’s Central Election Commission to announce ultra-right presidential candidate Dmytro Yarosh as the winner. Administrators detected the tampering less than an hour before the election results were set to be declared. And that attack was just a prelude to Russia’s most ambitious experiment in digital war, the barrage of cyberattacks that began to accelerate in the fall of 2015 and hasn’t ceased since.
Yushchenko, who ended up serving as Ukraine’s president from 2005 to 2010, believes that Russia’s tactics, online and off, have one single aim: “to destabilize the situation in Ukraine, to make its government look incompetent and vulnerable.” He lumps the blackouts and other cyberattacks together with the Russian disinformation flooding Ukraine’s media, the terroristic campaigns in the east of the country, and his own poisoning years ago—all underhanded moves aimed at painting Ukraine as a broken nation. “Russia will never accept Ukraine being a sovereign and independent country,” says Yushchenko, whose face still bears traces of the scars caused by dioxin toxicity. “Twenty-five years since the Soviet collapse, Russia is still sick with this imperialistic syndrome.”
