安全专家Bruce Schneier根据前NSA合同工Edward Snowden泄露的情报，在《卫报》上刊文描述了NSA跟踪Tor用户的策略：NSA在ISP合作下扫描整个互联网，创建指纹探测Tor网络向特定服务器发出的HTTP请求，它使用强大的数据分析工具自动筛选巨大的网络流量，寻找Tor网络连接。Tor匿名网络的强大之处同时也是它的薄弱环节——所有Tor用户的网络行为在互联网上看起来都没有差别，因此很容易将Tor用户与其他网络用户区分开来。为了识别个别的Tor用户，NSA使用它的秘密服务器网络中继Tor用户到另一组秘密服务器网络，对Tor用户计算机发动攻击，利用Tor浏览器组件的漏洞感染计算机。一旦Tor用户被感染，NSA随后发动后续的攻击对目标展开长期的监听。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
