怎么做木马

1,制作木马和使用木马病毒都是违法犯罪的行为,不建议您去学习。

2,制作出木马病毒程序后,这个程序就会自动开始执行,对您的电脑首先开始盗取帐号木马以及破坏程序。

3,所以如果自己受到了攻击或者盗号,不要用这种方式,要以正当途径来解决。

4,建议您到腾讯电脑管家官网下载一个电脑管家。

5,电脑管家拥有16层实时防护功能和QQ帐号全景防御系统,可以从上网安全、应用入口、系统底层等全方位保护电脑安全不受木马病毒侵袭,而且电脑管家还可以全方位多维度保护账号安全,精确打击盗号木马,瞬时查杀并对风险预警。

请介绍下C语言写木马的算法......

我只知道window的木马程序的原理,首先你要去研究一下windows PE文件的格式,windows PE文件包括(exe dll文件等),用文本方式打开任意一个exe或者dll文件,就会发现这些文件都具有类似的组织结构(就是PE格式)

仔细耐心地研究了PE格式后,你会发现这些PE格式的文件有很多间隙空间可用,window木马程序正是利用PE格式文件中的这些间隙,把自己的代码插入这些间隙空间中,同时还要修改宿主程序的入口地址(OEP Original Entry Point)

这样,宿主程序一运行,首先运行生成木马的代码,然后运行宿主程序。

Windows应用程序捆绑核心编程 (PE)

我得到了用VB编写的木马源码,我应该怎么编出木马

如果是在VB6下,可以运行“文件”菜单下的“生成.exe”命令得到目标程序;

如果是在vb.net下,可以运行“生成”菜单下的“生成”命令来编译工程。

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。
