任何人都可以在您的网络或远程计算机上使用包嗅探器查看交换的信息，有时甚至可以查看密码信息。
Anybody with a packet sniffer on your network or on a remote machine can view the information as it is exchanged, sometimes even password information.
例如，在最简单的情况中，网络嗅探能够用于获取密码，然后这些密码可以用于进行应用级攻击。
For example, in the simplest case, network sniffing is used to obtain passwords, and those passwords are then used to mount an application-level attack.
