　　You may think the only people capable of snooping on your Internet activity are government intelligence agents or possibly a talented teenage hacker holed up in his parents’ basement. But some simple software lets just about anyone sitting next to you at your local coffee shop watch you browse the Web and even assume your identity online.

　　也许你曾以为窥探你上网活动的事只有政府情报人员或者藏在自家地下室的青年黑客才会干的出来。但一些简单的软件使得哪怕是小咖啡馆里在你身边的任何人都可以看到你在浏览的网页甚至获得你的身份验证信息。

But a free program called Firesheep, released in October, has made it simple to see what other users of an unsecured Wi-Fi network are doing and then log on as them at the sites they visited.

　　不久前若要监视你的笔记本或智能手机通过Wi-Fi热点上网的情况，这还只是有能力和有毅力的黑客，花费大量时间并利用高精尖的工具才能办到的事。但去年十月发布的一款叫做Firesheep的自由程序使得监测未加密的Wi-Fi网络变得易如反掌，利用该软件人们可以监测别人上网信息乃至登录他人访问的网站帐户。

　　Without issuing any warnings of the possible threat, Web site administrators have since been scrambling to provide added protections.

　　在没有发布任何潜在安全威胁警告的情况下，网站管理员已经争先恐后的开始提供附加安全保护措施了。

　　What he means is that while the password you initially enter on Web sites like Facebook, Twitter, Flickr, Amazon, eBay and The New York Times is encrypted, the Web browser’s cookie, a bit of code that that identifies your computer, your settings on the site or other private information, is often not encrypted. Firesheep grabs that cookie, allowing nosy or malicious users to, in essence, be you on the site and have full access to your account.

　　More than a million people have downloaded the program in the last three months (including this reporter, who is not exactly a computer genius). And it is easy to use.

　　在过去三个月内超过一百万人已下载了该程序(包括对计算机并不在行的笔者在内)。它真的很简单易用。

PayPal and many banks do this, but a startling number of sites that people trust to safeguard their privacy do not. You know you are shielded from prying eyes if a little lock appears in the corner of your browser or the Web address starts with “https” rather than “

　　唯一安全的网站就是那些在整个会话过程中使用传输层加密协议或其前身SSL的网站。PayPal和许多银行做了这样的设定。但仍有一批数量惊人的网站没有这么做，而通常人们却一直相信它们能够保护其私人信息。当你的浏览器的一角出现一个小小的锁形图标或者你所访问的网址前以“https”而不是“http”开头时，你才能躲过那些窥视的眼睛。

　　“The usual reason Web sites give for not encrypting all communication is that it will slow down the site and would be a huge engineering expense,” said Chris Palmer, technology director at the Electronic Frontier Foundation, an electronic rights advocacy group based in San Francisco. “Yes, there are operational hurdles, but they are solvable.”

　　电子前哨基金会是一家总部位于旧金山的数字版权维权组织，它的技术总监克利斯·帕尔默说：“网站不提供全程通信加密的理由通常是，这会拖慢站点访问速度并造成巨大的工程开销。要提供全程通信机密的确有一些操作上的障碍，但这些困难都是可以解决的。”
