英国新闻听力 万名电脑黑客在洛杉矶集会

The Defcon Conference comes around each year. It’s when thousands of computer hackers² meet up in Los Angles. There are ten thousand attending this time, some employed by companies, most of them not. Dave Lee from our business unit is there. One of the main focuses this year has been the hacking³ of cars.

And that seems to be the big topic this year. Now of course many modern cars are connected to devices. And obviously computers are hacked⁴ and attacked all the time. So obviously the same goes for the cars that are being made in this way. Now we’ve seen several hacks⁵ at this event for example remotely controlling a Chrysler. So we saw in one demonstration⁶ and someone able to turn the radio up to crazy levels which doesn’t seem too bad. Chrysler has moved to fix that problem. But the concept shows that it’s potentially millions of cars out there. They aren’t as secure as perhaps they should be. So that’s a very very big topic. And we are also here in this week about a hack¹ on the Tesla cars. And there is very futuristic cars that are making ways at the moment. One of the researchers who found vulnerabilities in the Tesla explains to me what they did and why did it.

It is the most connected car on the road. And we want to see how it will handle from security issues. We want to see if there are any lessons that could be learned from it.

In Jamaica, there is a mini-war going on between police in transport officials on one side and illegal taxies on the other. The capital Kinston streets are clogged⁷ with taxies. Their passengers squashed into every available space. Some are legal but many are unregulated. And they are taking business away from the bus companies. The passengers want them but the authorities are clamping down. As Nick Davis reports.

It’s coming up to midday. It’s incredibly hot. One of the problems there is that you can wait for quite a while for one of these buses. So what often happens is you find normal taxis, red plates, licensed⁸ taxis operating around here. But you will also find illegal taxis.

That was me squashing into the back of a taxi. It had a red number plate. So it was legal. Licensed drivers here have insurance and run agreed specific routes. But its driver admits to me even they are pushing their luck with the authorities.

Defcon大会每年举行一次，届时数千名电脑黑客在洛杉矶集会。今年参会的人数有一万人，其中一部分是公司雇员，大部分则不是。本台商务板块同事大卫·李前方报道。今年大会的重中之重是黑客入侵汽车。

这似乎是今年的一个大议题。如今，许多现代汽车当然都和一些设备联在一起。而且很明显，计算机一直都是入侵和攻击的对象。所以如果将计算机原理运用于制造汽车，那么显然汽车也会遇到同样的风险。我们在这次大会上看到了几种黑客入侵的方式，例如，遥控一台克莱斯勒车。通过示范，我们看到有人可以把车上收音机的音量开得非常大，这看起来并不是太严重的问题。克莱斯勒已经努力解决了这个问题，但是这个概念表明可能还有上百万辆车达不到应有的安全标准。这是一个非常大的议题。我们这周聚集在一起还要讨论入侵特斯拉轿车的问题。目前人们正在发明很多极具未来主义色彩的车。有位研究员发现了特斯拉的弱点，他向我解释了他们的研究内容和研究目的。

它是陆地上连贯性最好的汽车。我们想看看它是如何处理安全问题的，想看看能否从它身上学到一些东西。大卫·李洛杉矶Defcon大会报道。

在牙买加，一场小型战争正在交警和非法出租车之间上演。首都金斯顿的大街上挤满了出租车。乘客努力挤进任何一个空车座。这些出租车中有些是合法的，但许多都是违章的。他们抢了公交车公司的生意。乘客需要这些出租车，但政府正在向它们施压。尼克·戴维斯报道。

现在已经是正午了，天气相当热。这个地方有一个问题，就是等公交车的时间太长了。所以人们经常会去找正常营业的出租车，红色牌照，有驾驶许可证。但也会有非法出租车。

这就是我挤进出租车后座的过程。这辆出租车车牌照是红色的，所以是合法的。在这里，得到许可的司机有保险、按照协议规定的特定路线驾驶。但出租车司机向我透露，即使是他们和政府部门打交道也得碰运气。
