你的车钥匙包了没？
As technology evolves, so does thievery. And while that wireless key fob might make getting into your car pretty easy, it turns out it's quite easy to hack.
随着技术的发展，偷窃技术也越来越高。虽然无线车钥匙可能会让你进入自己的车相当容易，但事实证明它很容易被黑。
With an unprotected fob, thieves can intercept the signal from the fob to a car with a special receiver, known as a “relay attack”. They can then use this to enter the car and even turn on the ignition. But there's a simple solution, as it appears just wrapping your fob in foil prevents the signals from being transmitted.
如果你车钥匙的信号没有被保护，黑客可以很容易地用一个特殊的接收器截取信号，这被称为“继电器攻击”。截取信号之后，他们便能够以此来解锁汽车，甚至启动汽车。但是一个简单的举措就可以防止这种事情的发生——你只需要用铝箔纸包裹住你车的遥控钥匙。
“Although it's not ideal, it is the most inexpensive way,” Holly Hubert, a cybersecurity expert, told the Detroit Free Press. “The cyber threat is so dynamic and ever changing, it’s hard for consumers to keep up.”
网络安全专家霍利·休伯特对底特律自由出版社表示：“尽管这样做的效果并不十分理想，但却简单易行。在如今这个时代，网络威胁是如此的变化多端，消费者很难跟上其步伐”。
According to Wired, the attack tricks the car and your key into thinking they're in close proximity of each other. “One hacker holds a device a few feet from the victim's key, while a thief holds the other near the target car,” they said. “The device near the car spoofs a signal from the key.”
据《连线》杂志报道，这种手段会蒙骗你的汽车和车钥匙，让它们以为彼此靠得很近。黑客只需要在距离受害者的无线车钥匙几米左右的地方用一个设备接受信号，小偷则手持另一台设备在目标车辆附近。当黑客截取到信号后，小偷身上的装置则会模拟出车钥匙的信号。
While it appears that ordinary foil will do the trick, Hubert suggests purchasing a Faraday bag, a small bag lined with metallic material to prevent signals from going in or out. You can use them for other devices too, like phones or tablets.
虽然普通的铝箔纸就会起到作用，但休伯特建议消费者们购买法拉第袋——一种内衬金属材料的小袋子，以防止信号进入或流出。你也可以把它们用于其他设备，比如手机或平板电脑。
Speaking to ABC News, the National Insurance Crime Bureau said there had been no confirmed cases of a relay attack in the US. However, it does appear to be a known risk that car companies are trying to tackle, and there have been unverified reports of such attacks.
美国国家保险犯罪局在接受美国广播公司采访时表示，美国国内还没有经过证实的“继电器攻击”事件，但确实有未经证实的此类攻击报告。所幸的是，各大汽车公司都在试图解决这种风险。
In the UK, Bristol resident Kieran Bingham claimed someone had broken into his car with a fake wireless fob. He said that when he went in the car, he found the glove box had been opened and items had been scattered, reports the Bristol Post.
但在英国，布里斯托尔的居民基兰·宾汉姆声称有人用这种手段闯入了他的汽车。据报道，当基兰上车的时候，他发现手套箱被打开了，各种物品四处散落在车内。
“My thinking is someone is going round hacking wireless keys,” Bingham said. “That’s why I’ve wrapped it in foil, to stop the device finding your keys.”
宾汉姆表示：“我认为有人正在四处窃取无线车钥匙的信号，这就是为什么我把我的车钥匙用铝箔纸包起来——防止信号被窃取”。
It’s not just foil that can stop thieves though. A fridge or freezer, microwave oven, or even a metal biscuit tin can also apparently stop the signal from being intercepted.
不过，不仅仅是铝箔纸可以阻止小偷。冰箱或冰柜，微波炉等只要是能够屏蔽信号的，都可以起到作用。
