Can My Network be Breached if I Join a War Zone Using an Ubuntu VM?
Joining a war zone using an Ubuntu VM can potentially expose your network to security risks. If your VM is accessible to other participants, it could be attacked and compromised, allowing attackers to potentially breach your home network.
While the likelihood of a breach may be low for a default install with no services running, it is important to be cautious about the services you expose. As the website warns, a properly configured firewall can help mitigate most issues.
