通过PowerShell获取Windows系统密码Hash

当你拿到了系统控制权之后如何才能更长的时间内控制已经拿到这台机器呢?作为白帽子,已经在对手防线上撕开一个口子,如果你需要进一步扩大战果,你首先需要做的就是潜伏下来,收集更多的信息便于你判断,便于有更大的收获.用什么方法才能有尽可能高的权限,同时能更有效的隐藏自己,是留webshell,留后门,种木马还是Rootkit?webshell,哪怕是一句话木马都很容易被管理员清除,放了木马,也容易被有经验的管理员查出,不管是早期自己创建进程,进程被干掉就完了,还是注入进程的木马,或者是以服务自启动的木马

使用C语言获取linux系统相关信息

最近在写shell的时候,涉及到了获取环境变量参数和本地计算机相关信息,包括计算机设备名,用户名的信息,在这里简单总结一下.获取环境变量各项参数,可以直接使用getenv函数.man中关于getenv函数的声明如下: #include <stdlib.h> char *getenv(const char *name); 函数中,参数name 为环境变量的名称, 如果该变量存在则会返回指向该内容的指针. 环境变量的格式为name＝value.执行成功则返回指向该内容的指针, 找不到符合的环境变量
