你的車鑰匙包了沒？
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.
隨著技術(shù)的發(fā)展，偷竊技術(shù)也越來越高。雖然無線車鑰匙可能會讓你進入自己的車相當容易，但事實證明它很容易被黑。
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.
如果你車鑰匙的信號沒有被保護，黑客可以很容易地用一個特殊的接收器截取信號，這被稱為“繼電器攻擊”。截取信號之后，他們便能夠以此來解鎖汽車，甚至啟動汽車。但是一個簡單的舉措就可以防止這種事情的發(fā)生——你只需要用鋁箔紙包裹住你車的遙控鑰匙。
“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.”
網(wǎng)絡(luò)安全專家霍利·休伯特對底特律自由出版社表示：“盡管這樣做的效果并不十分理想，但卻簡單易行。在如今這個時代，網(wǎng)絡(luò)威脅是如此的變化多端，消費者很難跟上其步伐”。
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.”
據(jù)《連線》雜志報道，這種手段會蒙騙你的汽車和車鑰匙，讓它們以為彼此靠得很近。黑客只需要在距離受害者的無線車鑰匙幾米左右的地方用一個設(shè)備接受信號，小偷則手持另一臺設(shè)備在目標車輛附近。當黑客截取到信號后，小偷身上的裝置則會模擬出車鑰匙的信號。
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.
雖然普通的鋁箔紙就會起到作用，但休伯特建議消費者們購買法拉第袋——一種內(nèi)襯金屬材料的小袋子，以防止信號進入或流出。你也可以把它們用于其他設(shè)備，比如手機或平板電腦。
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.
美國國家保險犯罪局在接受美國廣播公司采訪時表示，美國國內(nèi)還沒有經(jīng)過證實的“繼電器攻擊”事件，但確實有未經(jīng)證實的此類攻擊報告。所幸的是，各大汽車公司都在試圖解決這種風險。
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.
但在英國，布里斯托爾的居民基蘭·賓漢姆聲稱有人用這種手段闖入了他的汽車。據(jù)報道，當基蘭上車的時候，他發(fā)現(xiàn)手套箱被打開了，各種物品四處散落在車內(nèi)。
“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.”
賓漢姆表示：“我認為有人正在四處竊取無線車鑰匙的信號，這就是為什么我把我的車鑰匙用鋁箔紙包起來——防止信號被竊取”。
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.
不過，不僅僅是鋁箔紙可以阻止小偷。冰箱或冰柜，微波爐等只要是能夠屏蔽信號的，都可以起到作用。
