[Debugging Technology] View PEB and TEB in user mode
Overview: View processes PEB and TEB in user mode (exe attached or started for debugging through windbg) 0x01 View TEB and PEB in user mode During dual-machine debugging, you can directly use !PEB PID and !TEB TID to obtain relevant information about processes and threads. These two commands will be invalid in user mode. The […]
