Research direction

Reproduce the Windows case by launching the PE through cmd.exe with stdin redirected from data_to_send_in_stdin.bin, then compare the requested behavior with the linked x64dbg DbgChild plugin. Done means Binary Ninja's debugger automatically attaches to and debugs the child process, including hitting breakpoints.

Description

DbgEng Adapter enhancement functionality Impact: Medium

Hi,

What is the feature you'd like to have?

Be able to auto attach/debug child process using binja debugger on Windows.

Is your feature request related to a problem?

I have a program (PE) that requires user input to be sent to stdin. I haven't found any method other than using “cmd.exe /c program.exe < data_to_send_in_stdin.bin”. But as cmd launches a new process (program.exe), the latter is not debugged.

Additional Information:

Debug adapter settings for send stdin data to the program, but not debugged (breakpoints not hits):
