Wireless Protected Setup (WPS): Prestandajämförelse mellan Reaver och Bully

Abstract [sv]

Wireless Protected Setup (WPS) är ett säkerhetsprotokoll för trådlösa nätverk. Dess design medför en allvarlig säkerhetsbrist som kan möjliggöra att obehöriga kan få åtkomst till ett lösenordskyddat trådlöst nätverk. Vid attack finns det olika verktyg tillgängliga att använda.

I denna rapport jämförs mjukvaruverktygen Reaver och Bully i attack mot WiFi’s WPS-protokoll, där Bullys prestanda tidigare har påvisats vara mer effektiv och förutsätts snabbare utföra brute-forceattack jämfört med Reaver. Ett praktiskt laborationsexperiment har utförts för att undersöka vilken skillnad i hastighet som kan ses mellan verktygen Reaver och Bully i en brute-forceattack. Experimentet utfördes genom att mäta tiden det tog för de två verktygen att testa 100 PIN-nycklar mot en router utan skyddsmekanismer hos WPS.

Resultatet visar att Bully utför en brute-forceattack i högre hastighet jämfört med Reaver. Dock, med den högre attackhastigheten som Bully innehar, kan stabilitetsproblem vid attack medföras, vilket öppnar upp för framtida diskussion om högre hastighet bör prioriteras över stabilitet för lyckade attacker.

Abstract [en]

Wireless Protected Setup (WPS) is a security protocol for wireless networks. Its design contains a serious security flaw that could allow an attacker access to a password-protected wireless network. An attack can be executed using various tools available.

In this report, the software-tools Reaver and Bully are compared in performance against WiFi’s WPS-protocol, where Bully previously has been shown to be more effective and predicted faster to execute a bruteforce-attack. A practical laboration has been executed in order to determine differences in speed that can be seen between the tools Reaver and Bully in a bruteforce-attack. The experiment was done by measuring the time it took both tools to test 100 PIN-numbers against a router without protection for WPS.

The result shows that Bully performs a bruteforce-attack in higher speed compared to Reaver. However, with the higher attack-speed that Bully uses, some stability issues may follow, opening the topic of future discussion regarding priorities of speed vs. stability for successful attacks.
