Warcruising is a form of hacking that involves scanning and exploiting vulnerabilities in wireless networks, particularly those associated with vehicles. It typically entails using a laptop or a mobile device equipped with specific software tools while driving around urban or suburban areas to identify unprotected systems. The term combines "war driving," which refers to the practice of searching for Wi-Fi networks, with "cruising" to emphasize the mobile aspect of the activity. Warcruising can raise concerns about security and privacy, especially as vehicles become increasingly connected.
