!eb, !ed, !eq (edit physical memory)
Description of '!eb, !ed, !eq' commands in HyperDbg.
Command
!eb : edit memory as Byte values
!ed : edit memory as Double-word values (4 bytes)
!eq : edit memory as Quad-word values (8 bytes)
Syntax
!eb [Address (hex)] [Contents (hex)]
!ed [Address (hex)] [Contents (hex)]
!eq [Address (hex)] [Contents (hex)]
Description
Edits the physical address memory contents.
Parameters
[Address (hex)]
The physical address of where we want to edit its memory.
[Contents (hex)]
The new contents in hex format.
Process ID doesn't make sense in physical memory. If you specify pid for physical memory, it is ignored.
Examples
The following command is used when we want to edit the content of physical memory at 1000 in a hex byte form and change it to 0x90 0x90 0x90 (modify three bytes).
The following example is used when we want to edit the contents of physical memory at 1000 in Double-word values (4 bytes), change it to 245C8948 .
The following example is used when we want to edit the contents of physical memory at @rax+@rbx+5 in Double-word values (4 bytes), change it to 245C8948 .
The following example is used when we want to edit the contents of physical memory at 1000 in Quad-word values (8 bytes), change it to 88889898`85858686 and92929393`97979898 (16 bytes).
SDK
To write the memory in the target debuggee, you need to use the following function in libhyperdbg:
Remarks
You can change as many bytes as you need in byte, dword, and qword formats. Just add new values to the end of the command.
This command is guaranteed to keep debuggee in a halt state (in Debugger Mode); thus, nothing will change during its execution.
Requirements
None
