In public wireless networks, unauthorized interception of sensitive information of others is an illegal and criminal act. Our country's law expressly stipulates and severely crack down on such criminal acts. Relevant state departments continue to strengthen network security protection to ensure the people's network security and personal information security. We call on the majority of Internet users to abide by laws and regulations, not to participate in any form of cybercrime activities, and to jointly maintain a good online environment. If you find such illegal acts, please report to the public security organs immediately. Citizens themselves should also raise their awareness of network security, use complex passwords, avoid sensitive operations in a public network environment, and protect the security of their personal information.
