【一起听英语】网络犯罪（在线收听）

网络的发展，给我们带来便利的同时，也带来了问题。其中之一就是网络犯罪....

Dan: Hello, I'm Dan.

Rob: And I'm Rob.

Dan: And this is 6 Minute English! This week we're talking about cyber crime.

Rob: Yes, cyber crime. It's something we're hearing more and more about. This is

crime that takes place over a computer network.

Dan: Rob, have you ever been the victim of cyber crime?

Rob: Well, I don't think so. I always use security software on my computer and keep

all my passwords private.

Dan: That's a good idea. I do the same but it still seems possible for hackers to

access our computers. More on that in a minute but first I have a question for

you, Rob.

Rob: I thought you might!

Dan: Well, here goes. According to a recent UK government study, how much does

cyber crime cost the UK economy? Is it:

a) £27 million a year

b) £27 billion a year, or

c) £270 billion a year

Rob: I’d take a guess at £27 million a year.

Dan: OK, well, as usual, I'll tell you the correct answer at the end of the programme.

Now let's talk a bit more about what's happening in the world of cyber crime.

Rob: This online crime is becoming more commercialised and this is what experts

were recently discussing at a meeting in London.

Dan: So criminals are carrying out illegal practices online and cashing in on them

by selling their services to other people.

Rob: And internet security experts want to stop this.

Dan: That’s right. They're calling it a cyber war. It's a sort of virtual war. But who

exactly are they fighting?

Rob: Well, it's computer hackers, many of who are teenagers working on their

computers at home.

Dan: But there's a worry their work is overlapping with the world of criminal

networks. And Charlie McMurdy of the Police Central e-crime Unit says this

work is international.

Every investigation has international aspects to it. You don't have to, like your old, say,

the armed robbery team who used to meet in the dark and dangerous pub… Well, on

the internet you can meet virtually and work as a criminal enterprise, even though

you’re in different parts of the world.

Dan: Charlie McMurdy says cyber crime is different from old fashioned crimes.

Criminals can meet virtually anywhere and work as a criminal enterprise - like

a business.

Rob: So they meet virtually. They don't meet physically, face to face, but they

communicate via the internet.

Dan: Yes. It's a big problem. Did you know there are nine new unique threats

detected every second in cyberspace?

Rob: Wow, that is a lot. And what exactly do they do?

Dan: Well, they are hijacking - or taking over - home computers and turning them

in to botnets.

Rob: Botnets - tell us more about that, Dan.

Dan: Well, these are a network of computers taken over by hackers and used for

malicious purposes. They infect the computers with software that enables

them to control them remotely.

Rob: And this sort of activity is becoming more commercialised?

Dan: It is. Tony Osborn from security company Symantec uses another word,

'industrialised'.

Insert 2: Tony Osborn, Symantec

What we’ve found over the last few years is a maturing, so it's like the industrialisation

of this business. Part of one organisation might be selling botnet facilities, so you can

rent our botnet for $100 or whatever, and that will give you access to these number of

devices. And that you give us the malicious code, the malware, the spam and we will

inject that into the botnets, and for a period of time we will then send those out.

Dan: Tony Osborn says the business is maturing.

Rob: So that means it's fully developed and it's becoming big business. One

example is hackers renting out access to botnets. They give you access to a

number of devices for a fee - for money.

Dan: And then they inject your malicious codes, malware and spam into other

people's computers.

Rob: Spam. That's when you send the same message indiscriminately to a large

numbers of recipients on the Internet.

Dan: And we don't have much control over this. But the UK government is planning

to spend £650 million on improving cyber security. But what should it be spent

on? John Bassett from the Royal United Services Institute thinks there are

number of priorities.

How that is going to be spent in the context of the Ministry of Defence, how that's going

to be spent in terms of network defence overall. What's going to be done in terms of

public awareness, what are we going to do about bringing on more cyber experts? All

four of those, I think, are important and the cornerstone of good cyber security has to be

based on education.

Dan: So John Bassett is talking about areas of cyber security where he thinks money

could be spent. And he talked about education and public awareness.

Rob: Public awareness is all about educating people on good cyber security. The

risks from cyber crime are everywhere, from fraud to espionage and even

cyber warfare.

Dan: It seems to be the big crime of the 21st century and it's costing us a lot of

money.

Rob: That's right, and Dan, earlier you asked me a question. According to a UK

government study, how much is it costing the economy? £27 million a year,

£27 billion a year or £270 billion a year?

Dan: And you said?

Rob: I said £27 million a year. Am I right?

Dan: No, you’re not! It's actually £27 billion a year, and that's a lot of money.

Rob: It really is, isn’t it, yeah.
