Looming

Today, the full scale of the threat Sandworm and its ilk present looms over the future. If cyberwar escalation continues unchecked, the victims of state-sponsored hacking could be on a trajectory for even more virulent and destructive worms. The digital attacks first demonstrated in Ukraine hint at a dystopia on the horizon, one where hackers induce blackouts that last days, weeks, or even longer - intentionally inflicted deprivations of electricity that could mirror the American tragedy of Puerto Rico after Hurricane Maria, causing vast economic harm and even loss of life. Or one where hackers destroy physical equipment at industrial sites to cause lethal mayhem. Or, as in the case of NotPetya, where they simply wipe hundreds of thousands of computers at a strategic moment to render brain-dead the digital systems of an enemy's economy or critical infrastructure.
