NP启动后通过WriteProcessMemory跟CreateRemoteThread向所有进程注入代码（除了系统进程smss.exe），代码通过np自己的LoadLibrary向目标进程加载npggNT.des。npggNT.des一旦加载就马上开始干“坏事”，挂钩(HOOK)系统关键函数如OpenProcess,ReadProcessMemory,WriteProcessMemory,PostMessage等等。

挂钩方法是通过改写系统函数头，在函数开始JMP到npggNT.des中的替换函数。用户调用相应的系统函数时，会首先进入到npggNT.des模块等待NP的检查，-NP starts with CreateRemoteThread via WriteProcessMemory inject code to all processes (in addition to system process smss.exe), np own code through LoadLibrary to load the target process npggNT.des. npggNT.des Once loaded immediately start doing "bad", hooks (HOOK) system-critical functions such as OpenProcess, ReadProcessMemory, WriteProcessMemory, PostMessage and so on.

Hook method is through rewriting system function head start in the function of JMP to npggNT.des replacement function. Users call the corresponding system function, will first enter into npggNT.des module waits for NP examination,
