But this rush to become a smart city has a major drawback: The more connected a city is, the easier it is to cyber-attacks. Hackers have, in recent years, effectively held cities hostage through ransom ware(赎金器), sometimes damaging critical systems for months at a time. The damage can cost millions to repair, as Baltimore and Atlanta have discovered.
And this is just the beginning. As cities add connectivity to their streetlights, power grids, dams, transit lines and other services, they are adding more targets that have the potential to be hacked. What’s more, as additional information on residents is collected, officials worry the result —lots of data could attract nation-states or terrorists who could incorporate the data into physical and cyber war.
What cyber security lesson can’t be taught in this hack? For example: Don’t open email attachments from unfamiliar sources; don’t click on unrecognized links; don’t leave sensitive information visible on the walls or surfaces of your office. But let’s just stick to the most important lesson: The information you share on social media can be used to profile and target you, whether that’s by engineering click bait(点击诱饵) aimed at your particular interests, guessing your password based on your birthday or figuring out your schedule and travels so that an intruder can access your home or office.
