一些熟悉这类程序的网络专家指出,Internet上广泛使用的“即时信息”服务面临着严重的安全问题。ICQ对于拦截、欺骗和其它敌意程序缺乏安全保障,这些敌意程序可以窃听系统发出的私人和敏感信息。每天在Internet上超过300万人使用ICQ向朋友和同事发送快速简单的文本信息,这些信息在用户桌面窗口中即时显示。超过1200万用户注册了ICQ,该程序在办公室职员中同样大受欢迎,例如用来交换销售数字这类的信息。 Some network experts familiar with such programs point out that the “instant messaging” services widely used on the Internet face serious security problems. ICQ lacks security for interception, deception and other hostile procedures that can eavesdrop on private and sensitive information sent by the system. Every day, more than 3 million people on the Internet use ICQ to send quick and easy text messages to friends and colleagues, instantly displayed in the user’s desktop window. More than 12 million users have signed up for ICQ, a program that is equally popular among office workers, such as those used to exchange sales figures.
