解析无诱饵钓鱼欺骗是一种诡秘的做法，其中恶意代码会装入个人计算机或服务器，在不知不觉中或者未经用户同意就将用户错误地引向骗人的网站。它被叫做“无诱饵钓鱼”。在钓鱼式欺骗中，为了从收信个人那里获得个人和财务信息，作恶者发送似乎是合法的电子邮件，看上去它来自某个最流行的网站。而在无诱饵钓鱼欺骗中，由于它不是一个一个地针对个人，受害方丝毫不会怀疑这些行为，因此会有大量的计算机用户受害。其中一种无诱饵钓鱼欺骗的形式就是，随电子邮件发出的（恶意）代码修改个人计算机上的本机主文件。该主文件将URL转换成计算机访问网站的数码串。拥有修改过的主文件的计算机会去假冒网站，即使用户键入了正确的因特网地址或者点击了受影响的书签条目。有些消除间谍件的程序能纠正此种破坏，但除非用户改变了浏览习惯，否则它还是会频繁发生。
