How Waircut Works
Waircut operates by conducting a series of tests on your Wi-Fi network, particularly targeting the WPS (Wi-Fi Protected Setup) protocol. It uses various algorithms and techniques to attempt unauthorized access, simulating potential attacks a hacker might use. Here’s a breakdown of its core functionalities:
WPS Pin Attack
WPS (Wi-Fi Protected Setup) is a feature that simplifies the process of connecting devices to a Wi-Fi network by using an 8-digit pin. However, this convenience also presents a security risk, as the pins can be relatively easy to guess. Waircut exploits this weakness by attempting different WPS pins to gain access to the network. Here’s how it works:
- Predefined Pin List: Waircut uses a predefined list of WPS pins that are known to be vulnerable. These pins are often factory defaults that have not been changed by the user.
- Pin Guessing: The tool systematically tries each pin from the list to see if it can successfully connect to the network.
- WPS Pin Validation: Once a pin is guessed correctly, Waircut gains access to the network, demonstrating the vulnerability of using WPS.
Brute Force Attack
A brute-force attack is a method used to break into a system by systematically trying all possible combinations until the correct one is found. In the context of Waircut, the brute force attack targets the WPS pin:
- Exhaustive Search: Waircut attempts every possible combination of the 8-digit WPS pin. This process can be time-consuming but is effective if the WPS feature is enabled and the pin has not been changed from its default value.
- Pin Verification: For each pin attempted, Waircut checks whether it can gain access to the network. If successful, it indicates that the network’s WPS implementation is vulnerable to brute-force attacks.
- Time Considerations: While brute force attacks are thorough, they can take a considerable amount of time, especially if the network implements lockout mechanisms after several failed attempts.
Vulnerability Scanning
Vulnerability scanning is a crucial step in assessing the security of a Wi-Fi network. Waircut performs comprehensive scans to identify known vulnerabilities.
- Network Discovery: Waircut scans the available Wi-Fi networks to gather information about them, including SSID (network name), signal strength, encryption type, and whether WPS is enabled.
