Mathy Vanhoef, Frank Piessens
2013 Proceedings of the 8th ACM SIGSAC symposium on Information, computer and communications security - ASIA CCS '13  
We describe three attacks on the Wi-Fi Protected Access Temporal Key Integrity Protocol (WPA-TKIP).  ...  We also report on implementation vulnerabilities discovered in some wireless devices. Finally we demonstrate that our attacks can be executed in realistic environments.  ...  EXPERIMENTS In this section we begin by investigating whether TKIP is still supported in practice.  ...

Multi-Channel Man-in-the-Middle Attacks Against Protected Wi-Fi Networks: A State of the Art Review [article]

Manesh Thankappan, Helena Rifà-Pous, Carles Garrigues
2022 arXiv   pre-print
Since its inception in 2014, attackers have been targeting WPA Wi-Fi networks to perform different attacks, such as cipher downgrades, denial of service, key reinstallation Man-in-the-Middle (MitM) attacks  ...  We examine practical issues that hamper the total adoption of protection mechanisms, i.e., Security security patches and Protected Management Frames (PMF), and review available defense mechanisms in FragAttacks  ...  We would also thank Mathy Vanhoef for his help by answering some of our queries and providing source codes related to MC-MitM attacks.  ...

Evaluation of Enhanced Security Solutions in 802.11-Based Networks [article]

Ifeyinwa Angela Ajah
2014 arXiv   pre-print
Traditionally, 802.11-based networks that relied on wired equivalent protocol (WEP) were especially vulnerable to packet sniffing.  ...  Comprehensive in-depth comparative analysis of each of the security mechanisms is driven by review of related work in WLAN security solutions.  ...  It was argued in [11] that WPA was not really cracked. According to him, the vulnerability seen in WPA was due to a poor deployment of WPA-PSK.  ...

Modelling of 802.11 4-Way Handshake Attacks and Analysis of Security Properties

R. Singh, J. Moreira, T. Chothia, M. Ryan
2020 Zenodo  
We nd that our Tamarin models vulnerable to the KRACK attacks do not violate any of the standard's security properties, indicating that the properties, as speci ed by the standard, are insucient.  ...  We propose an additional security property and show that it is violated by systems vulnerable to KRACK attacks, and that enforcing this property is successful in stopping them.  ...  Clients can either actively send and receive probes, or just observe the broadcast beacons passively to learn the supported cipher suites (e.g., TKIP and/or AES-CCMP), and version of WPA.  ...
