What does War Chalking refer to?

• A. Encrypting wireless networks
• B. Marking locations of wireless networks with chalk on sidewalks
• C. Data exfiltration through wireless
• D. Deploying rogue APs

Answer: (B)

War chalking is the practice of drawing marks on sidewalks or walls to indicate the presence of wireless networks nearby. These chalk symbols were used by wardrivers to quickly convey information about a network—such as that it exists and, sometimes, what kind of security it uses—so others can find and assess or access it. It’s a form of reconnaissance tied to wireless discovery, often discussed in the context of urban mapping of Wi‑Fi coverage. This is different from encrypting wireless networks, exfiltrating data over wireless, or deploying rogue access points, which are separate activities.
