The phone rings. Through sleep-blurred eyes, you see that the alarm clock reads 2:37 a.m. Grasping, you reach the noisy thing on the dark bedside table. An 800-number glows on the screen. You answer, confused and appropriately peeved. “Uh, hello?” you say. “Hello, this is AT&T calling. We are sorry to bother you at this hour, sir, but our system shows that your computer is currently being used in a cyber attack on the Internal Revenue Service. We are informing you that your home will be disconnected from the Internet entirely until the issue has been resolved. Thank you. Goodbye.”
