一个进程如何访问外部TIB? [英] How can one process access foreign TIB?

问题描述

是否有可能(以及如何)访问某个其他进程的线程的线程信息块?

Is it possible (and how) to access Thread Information Block of a thread of some another process?

推荐答案

有可能.

第一步是使用NtQueryInformationThread 函数，ThreadInformationClass 设置为 ThreadBasicInformation.THREAD_BASIC_INFORMATION 结构包含指向线程 TEB 的指针.然后你可以使用 ReadProcessMemory 和 WriteProcessMemory 以读取或修改 TEB 的内容.

The first step is to get the adress of the Thread Information Block by using the NtQueryInformationThread function with ThreadInformationClass set to ThreadBasicInformation. The THREAD_BASIC_INFORMATION structure contains a pointer to the TEB of the thread. Then you can use ReadProcessMemory and WriteProcessMemory in order to read or modify the content of the TEB.
