How do wireless re-authentication attacks steal PSK?
Best insight from top research papers
Wireless re-authentication attacks steal PSK by exploiting vulnerabilities in the authentication protocols used in wireless networks. These attacks aim to capture the keys exchanged during the re-authentication process, compromising network security. One such attack is the de-authentication attack, which forces a wireless client to re-authenticate with the access point and captures the PSK during the handshake . Another type of attack is the relay attack, where an attacker relays information between two victims during the authentication protocol run, without needing to guess or obtain a common secret . Pilot contamination attacks are also a concern, where an attacker initiates an attack during the transmission of the second pilot, coinciding with the legitimate pilot . Additionally, replay attacks can be used to steal PSK by tricking a victim into reinstalling an already-in-use key .

What are some common methods used by hackers to gain unauthorized access to Android devices?5 answersHackers commonly use various methods to gain unauthorized access to Android devices. One prevalent technique is PHYjacking, where malicious apps mislead users to provide physical inputs, bypassing protection mechanisms and exploiting vulnerabilities in Android systems. Another method involves the use of Remote Access Trojans like Dendroid, which can steal sensitive information by requesting excessive permissions from users. Additionally, attackers may employ evasion and covert channels to disguise their activities and bypass security measures, making it challenging to detect their intrusion attempts. Furthermore, hackers exploit the increased usage of features like Instant Messaging, GPS, and webcams on Android devices to invade users' privacy, emphasizing the importance of implementing countermeasures to mitigate hacking tricks and enhance security levels.
Can bind the samba account to authenticate with wifi user?5 answersYes, it is possible to bind a Samba account to authenticate with a WiFi user. This can be achieved by using an authentication method based on WiFi access, where a terminal MAC address is bound to the Samba account. The method involves transmitting the IP address, equipment name, and domain name of the Samba client to an adaptation layer, which then acquires the corresponding MAC address from an ARP table. The adaptation layer checks if a mapping entry for the MAC address exists in a pre-stored mapping table, and if it does, the Samba client is granted access to the Samba server side within the permission scope set in the configuration file. This approach allows for convenient and secure access to the Samba server side without the need for the user to input a username or password every time.
What layer of Wsn is attacked?5 answersWireless Sensor Networks (WSNs) are attacked at different layers. In the provided abstracts, attacks are mentioned at the MAC layerand the network layer. Specifically, MAC layer attacks such as impersonation and energy drain attacks are discussed in the abstracts. Additionally, network layer attacks like Blackhole, Flooding, and Selective Forwarding attacks are also mentioned. These attacks target the communication and security protocols at their respective layers in the WSN architecture.
What are the re-authentication vulnerabilities in WPA2-PKM protocol?5 answersThe re-authentication vulnerabilities in the WPA2-PKM protocol have been identified in multiple papers. Ghanem and Ratnayake propose a novel re-authentication protocol that mitigates the risk of exposing the Pre-Shared Key (PSK) during the re-authentication process. Wu Meng shows that the PKM protocol of LMDS is vulnerable to forgery and replay attacks due to faults in the message structure. Jiang Yunfan and Liu Peng present a device and method for detecting vulnerabilities in the WPA2 protocol by monitoring and analyzing the communication data of the intelligent device under test. Tsitroulis, Lampoudis, and Tsekleves analyze the weaknesses of the WPA2 security protocol and propose enhancements to improve its security.
What are the main weaknesses of WPA2-PSK?5 answersThe main weaknesses of WPA2-PSK include vulnerabilities to hacking through exploiting specific weaknesses or guessing passwords using dictionary attacks. The 4-way handshake procedure in WPA2/PSK has been identified as a weakness, which can be exploited for authentication cracking. Additionally, WPA/WPA2-PSK mode is susceptible to dictionary attacks, where user passphrases can be acquired after capturing specific wireless packets. These weaknesses pose a serious risk to the security of home or enterprise WiFi networks.
What are the quantum attacks on BlueTooth?5 answersQuantum attacks on Bluetooth have been identified in recent research. These attacks exploit vulnerabilities in the Bluetooth specification, allowing for impersonation attacks during secure connection establishment. The vulnerabilities include the lack of mandatory mutual authentication, overly permissive role switching, and an authentication procedure downgrade. These attacks, known as Bluetooth Impersonation AttackS (BIAS), are effective against any standard compliant Bluetooth device, regardless of the Bluetooth version, security mode, device manufacturer, or implementation details. The attacks are stealthy because the Bluetooth standard does not require end users to be notified about the outcome of an authentication procedure or the lack of mutual authentication. The BIAS attacks have been successfully conducted against 31 Bluetooth devices from major hardware and software vendors.
