Some individuals engaged in wardriving are content to simply map the location any networks they find. Others with more malicious intent attempt to break into some of these networks. Although somewhat of a fad year ago, some also participated in warchalking, tagging nearby pavement with coded directions to allow others to find certain residential networks (usually, unsecured ones).
Wardriving has been a controversial practice from the beginning, but it did raise awareness of the importance of wireless network security and more residences have employed basic Wi-Fi security measures like WPA encryption. Occasional high-profile events such as Google Street View scanning Wi-Fi networks in 2010 have kept attention on this issue.
