第2862期:Ransomware
Episode 1
Now, we've already had a podcast about computer hacking，we're talking about a different kind of cybercrime, ransomware. Richard, what is ransomware? Well, it's a specific type of malware that blocks access to a computer and then demands money to release that computer. Oh, you mean like a ransom? It is a ransom, yes.我们之前做过一期关于电脑黑客的播客，但今天我们要讨论另一种网络犯罪——勒索软件。Richard，什么是勒索软件？嗯，它是一种特定的恶意软件，会阻止你访问电脑，然后要求付钱才能解锁。哦，就像是勒索？没错，就是勒索。
And it's in the news at the moment because? A lot of big companies have been hit with a latest piece of software. And basically they can't work unless they pay money. Yes, unless you've got a backup, of course.那它最近为什么上新闻呢？因为很多大公司都被最新的这款软件攻击了。基本上，他们付钱之前什么也做不了。是的，除非你有备份。
Right, okay. How does it work, Richard? How does ransomware work? Well, to get it on your computer, you have to open often an email that has an infected Word document or PDF. And then once you've opened that document, it's on your computer, and then it can spread to other computers on your network.好，那它是怎么运作的呢，Richard？勒索软件到底如何运行？通常，你需要打开一封包含受感染 Word 文档或 PDF 的邮件。一旦你打开了那个文档，它就进入你的电脑，然后可以扩散到你网络中的其他电脑。
If you're in a big company, it can go through the network very quickly. So you get it on your computer, right? Then what happens? Well, once it's on your computer, it encrypts all the files on that computer. Which means you can't access them? You can't.如果你是在一家大公司，它会非常迅速地在网络中传播。所以感染进入你的电脑后，会发生什么？它会加密你电脑上的所有文件。也就是说，你无法访问了？完全无法。
And a message pops up asking for payment to decrypt your computer and instructions on how to pay. And it threatens to destroy all the data on your computer if you don't pay, often within a time limit. And so what kind of amounts are they asking for? Not huge amounts per computer.然后屏幕上会弹出一个消息，要求你付钱才能解密你的电脑，并告诉你如何付款。如果你不付钱，它会威胁要销毁你电脑中的所有数据，通常还会设定时间限制。他们一般索要多少钱？对每台电脑来说不算很高。
This latest attack was $300. Right. And it's always, the problem is, of course, the payment is by Bitcoin.最近一次攻击的金额是 300 美元。对。而麻烦的是，他们总是要求用比特币支付。
Oh, no. Okay, we did another podcast all about Bitcoins. So that's the cyber currency.哦，不会吧。我们之前还做过一期关于比特币的播客。那是一种网络货币。
Yes. So presumably difficult to trace. Well, because I was going to ask you, Richard, who's behind it? Well, exactly.对。所以 presumably 就很难追踪。其实我正想问你，Richard，到底是谁在背后操控这些？没错，这正是问题所在。
