Core/villain_core.py: host and uname default values

[abuyusif01]

Sometimes the client wont give the username and hostname, especially if the terminal is not a tty. so villian will fail if it tries to get username from url_split.
This commit solves that by having a try block. if we succeed in retrieving hostname and username. then fine, else we set the default value to host, user respectively

Hi @abuyusif01, sorry for the huge delay. I didn't have time to monitor PRs for a long time. I already pushed a similar fix for this issue some time ago. I'm gonna close this, but if you want to appear in the contributors as this was a valid issue reported early, you can make a new PR replacing lines 1150-1158 in villain_core.py with this slightly improved version that informs the user of the undefined hostname and user. This concerns the dev branch that is ahead of main:

			try:
				Sessions_Manager.active_sessions[session_id]['Computername'] = url_split[1]
				Sessions_Manager.active_sessions[session_id]['Username'] = url_split[2]
				print_to_prompt(f'\r[{GREEN}Shell{END}] Backdoor session established on {ORANGE}{self.client_address[0]}{END}')

			except IndexError:
				Sessions_Manager.active_sessions[session_id]['Computername'] = 'Undefined'
				Sessions_Manager.active_sessions[session_id]['Username'] = 'Undefined'			
				print_to_prompt(f'\r[{GREEN}Shell{END}] Backdoor session established on {ORANGE}{self.client_address[0]}{END} (hostname and user undefined)')

Hi @t3l3machus

i've created a PR to the dev with the fix.

Thanks for reviewing the PR
