暗网,隐网,深网,听着很吓人,是吧。在媒体的推波助澜下,这些东西的确变得神秘而又不可触碰起来。但是,说实话,有什么难的呢,难道每个暗网用户都是计算机高手不成? 什么是暗网? 这里有点区别,倒不如这么说吧,无法直接由搜索引擎搜索到的页面都属于隐网,也就是The Hidden Web。 媒体搞了一个冰山理论,什么绝大多数的网络都是罪犯的天堂,也是可笑之极, 那我知乎的个人编辑页面也成为犯罪天堂咯?这里所要澄清的是,隐网的确很多,但是我们即将要讨论的暗网却并非如此。 暗网, 数量在几万左右,不时关闭,不时开启,有违法色情,毒品与枪支的交易,当然还有FBI的钓鱼网站。这也是大家所熟知的。如果要深入了解下具体,可以看看这篇文章:出于好奇,我去暗网里瞧了瞧 —— 你就别去了 暗网网站的网址一般都如此:,而这是无法用普通的浏览器访问的,而是一个加密浏览器,也就是我们的Tor。 如何使用Tor...
