unload (unload the kernel modules)

Description of the 'unload' command in HyperDbg.

Command

unload

Syntax

unload [remove] [ModuleName (string)]

Description

Unloads the HyperDbg drivers and kernel modules from the target system.

Parameters

[remove](optional)

If you want to remove the installed driver. (See Remarks for more information)

[ModuleName (string)]

The name of the module that you want to unload.

Modules

Module Name	Description
vmm	Hypervisor-related capabilities

The debugger functions are implemented on top of the 'vmm' module.

vmm : this module contains commands related to the debugger and all hypervisor-related capabilities. Currently, vmm is the only module of HyperDbg.

Examples

The following example unloads vmm module.

HyperDbg> unload vmm

IOCTL

This function first invokes IOCTL_TERMINATE_VMX to turn off the vmx operation and IOCTL_RETURN_IRP_PENDING_PACKETS_AND_DISALLOW_IOCTL to complete all the IRP Pending sessions so that we can call CloseHandle.

If you're using APIs, the following export in hprdbgctrl can be used.

HPRDBGCTRL_API int HyperdbgUnload();

Remarks

This command will continue the debuggee for some time (in Debugger Mode). This means that you lose the current context (registers & memory) after executing this command.

If you use the remove argument, then the driver will be marked to be stopped and uninstalled. You cannot re-load that module again until the target machine is restarted.

Requirements

None
