Shell是用户与操作系统交互的接口,负责接收并解释用户输入的命令;Kernel是操作系统的核心,负责管理硬件资源、进程调度等底层功能。 1. **Shell的作用**: - Shell(外壳)提供用户访问操作系统的途径,例如命令行界面(如Bash、CMD)或图形界面(如GUI)。 - 它不直接操作硬件,而是将用户指令转换为内核能理解的请求。2...

Shell俗称壳(用来区别于核 kernel),是一种“命令解析器”。按照ABS的定义,shell是The shell is a command interpreter. More than just the insulating layer between the operating system kernel and the user, it’s also a fairly powerful programming language。分为图形界面shell和命令行shell两大类。 Shell...

InMemoryOrderModuleList字段是一个指针,指向LDR_DATA_TABLE_ENTRY 结构体上的LIST_ENTRY字段,但是它不是指向LDR_DATA_TABLE_ENTRY 起始位置的指针,而是指向这个结构的InMemoryOrderLinks字段。 编写shellcode 3.1 c++库文件配合内联汇编 先来针对指定系统的shellcode的编写,指定系统的,我们首先通过LoadLibraryA函数导入相应...
