遭遇ARP欺骗
今天女朋友考试，于是背着小黑陪她到学校。没事儿干就跑到俺们学校图书馆插根网线儿上网。结果没一会儿，我还没登外网呢（俺们学校上外网要花钱）小红伞就开始弹警告。
什么ads.jpg.exe，这个是在IE临时文件夹里。另一些就是三位数字的.exe文件，在系统目录windows下，我晕，感情咱这么一下子就中病毒了？赶紧狂查，msconfig启动项，服务中，没有可疑项，开机的程序也没有可疑项。哦，感情这病毒还是绿色的，没事儿，自己不自动启动，得，哥们我重启下，结果一会儿只要用IE上网就又下载一堆子这些，我晕，IE的ADD-on里面也什么可疑项都没有啊，于是开opera，下载了个hijackthis查了查，还是什么都没有看到可疑的，中间还让校外一个哥们上我们学校网页，没有问题啊
这个时候就断网了
我晕，怎么会是，旁边的别人都好好得啊。我改个IP试一试，哟嗬，一改，好了，又能上了。突然想起来，嗯，这不是传说中的ARP欺骗么？病毒或者是我同子网的某人运行的程序伪装ARP包发送给大家，让大家都以他的电脑为网关上网，然后再html里面加上点儿貌似jpg的.exe文件，嗯，应该是这样的，嘿嘿。
大家给分析分析，应该是吧哈？ 附上hijackthis的log给高手们看看：
