NetExec allows you to create custom modules to extend its functionality. Here's a basic structure for a custom module:

from netexec.modules import Module

class CustomModule(Module):
    name = 'custom_module'
    description = 'Description of your custom module'
    supported_protocols = ['smb', 'mssql', 'winrm']
    opsec_safe = True
    multiple_hosts = True

    def options(self, context, module_options):
        '''
        Define any options for your module
        '''
        pass

    def on_login(self, context, connection):
        '''
        Perform actions when a successful login occurs
        '''
        context.log.success('Successful login')

    def on_admin_login(self, context, connection):
        '''
        Perform actions when a successful admin login occurs
        '''
        context.log.success('Successful admin login')

    def on_request(self, context, request):
        '''
        Perform actions for each request
        '''
        pass

    def on_response(self, context, response):
        '''
        Perform actions for each response
        '''
        pass

    def on_finish(self, context):
        '''
        Perform final actions when the module finishes
        '''
        context.log.success('Module finished')

To use your custom module, place it in the ~/.netexec/modules/ directory and run NetExec with the -M flag followed by your module name.

To maximize the effectiveness of NetExec modules:

• Always use the latest version of NetExec to access the most up-to-date modules
• Combine multiple modules for comprehensive assessments
• Use the -M flag followed by the module name to execute a module
• Some modules accept additional options; use netexec [protocol] -M [module] --options to view them
• Be cautious when using modules that make changes to target systems
• Test modules in a controlled environment before using them in real-world assessments
• Keep detailed logs of module usage for reporting and analysis
