D.
Evil twin

Explanation:
War chalking is the act of making chalk marks on outdoor surfaces (walls, sidewalks, buildings,
sign posts, trees) to indicate the existence of an open wireless network connection, usually
offering an Internet connection so that others can benefit from the free wireless access. The open
connections typically come from the access points of wireless networks located within buildings to
serve enterprises. The chalk symbols indicate the type of access point that is available at that
specific spot.
