Wardriving, the adventurous act of hunting for wireless networks while cruising around a specific area, has evolved into a fascinating yet potentially threatening phenomenon in the realm of cybersecurity. In this article, we’ll answer the question of what is wardriving, exploring its purposes, methodologies, legality, tools involved, and most importantly, how to detect yourself from potential threats.
The Whys and Hows
The Origins and Variations
Wardriving finds its roots in the concept of wardialing, as seen in the 1983 film WarGames. The name itself suggests a mobile exploration, but it is not confined to cars alone. Variations such as warbiking, warcycling, warwalking, warjogging, wartraining, and warskating involve different modes of transportation, each with its unique advantages and limitations.
What Drives Wardriving?
Wardriving serves a spectrum of purposes, ranging from benign activities like education, research, and site surveying to malicious intentions of exploiting vulnerable networks for criminal activities. Attackers may aim to steal personal information, including bank account details, emphasizing the need for vigilance in the ever-evolving landscape of cybersecurity.
Decoding the Mechanics of Wardriving
The Tools of the Trade
Wardriving requires a blend of hardware and software, including mobile devices like smartphones and laptops, wardriving software to crack Wi-Fi passwords, a wireless network card with a hi-gain antenna, and GPS for pinpointing network locations. The amalgamation of these tools enables wardrivers to identify and map vulnerable networks.
Legality of Wardriving
Wardriving, the act of searching for vulnerable Wi-Fi networks, is generally not illegal. However, legal boundaries can become unclear when wardrivers actively interact with networks or attempt unauthorized access. It’s important to understand and respect network security laws and regulations when engaging in wardriving. The concept of piggybacking, using someone else’s Wi-Fi without permission, further complicates the legal considerations.
Tools of the Trade: Software & Hardware
Wardrivers employ a variety of tools, including wardriving software or apps, smartphones, laptops, GPS, wireless network cards, antennas, and tools for generating maps from crowd-sourced databases. Understanding these tools provides insight into the mechanics of a wardriving attack.
Fortifying Your Wi-Fi Network
Protecting yourself from wardriving begins with securing your Wi-Fi network. Utilizing a VPN router adds an extra layer of encryption, safeguarding your data from potential threats. Turning off your router when not in use, changing default credentials, enabling multi-factor authentication, using the highest network security protocol, adding a guest network, and installing a firewall are key measures to enhance your network’s security.
Keeping Wardrivers at Bay
Educating yourself on the preventive measures against wardriving is crucial. From maintaining updated devices and router software to understanding the importance of a VPN router, these steps contribute to a robust defense against potential attacks.
1. Is wardriving illegal?
Answer: Wardriving itself is not illegal, but legal considerations arise when wardrivers actively interact with Wi-Fi networks, especially attempting unauthorized access. Piggybacking, accessing Wi-Fi without permission, adds complexity to its legal status.
2. What tools do wardrivers use?
Answer: Wardrivers use a combination of software and hardware, including software, smartphones or laptops, GPS, wireless network cards, antennas, and tools for generating maps.
3. How can I protect myself against wardriving?
Answer: Protecting yourself involves securing your Wi-Fi network with a VPN router, turning off the router when not in use, changing default credentials, enabling multi-factor authentication, using the highest network security protocol, adding a guest network, and installing a firewall.
4. Is wardriving still a threat in recent times?
Answer: While it has become less popular due to increased wireless network security, it still poses a threat. Taking preventive measures, such as installing a VPN on your router and keeping software updated, remains essential.
5. What is the purpose of wardriving?
Answer: The purpose is to find vulnerable networks for exploitation. This can involve the theft of personal information and potentially lead to criminal activities.
