This were called Warchalking (WAR РWirless Access Revolution and chalk). You could find a lot of signs which mean where WiFi is protected weakly and where security is strong. It is hard to find something harmful in this game. However times have changed and today this issue looks different.

What has changed? Currently people share a lot of private materials inside their networks. Also most of routers have secured WiFi by default.
