One of the most commonly used attacks under evil twins is a captive portal. At first, the attacker would create a fake wireless access point that has a similar ESSID to the legitimate access point. The attacker then might execute a denial-of-service attack on the legitimate access point which will cause it to go offline. From then on, clients ...
Sequence diagram for a Wi‑Fi deauthentication attack. Unlike most radio jammers, deauthentication acts in a unique way. The IEEE 802.11 (Wi-Fi) protocol contains the provision for a deauthentication frame. Sending the frame from the access point to a station is called a "sanctioned technique to inform a rogue station that they have been ...
A "soft access point" (soft AP) can be set up on a Wi-Fi adapter using for example Windows' virtual Wi-Fi or Intel's My WiFi. This makes it possible, without the need of a physical Wi-Fi router, to share the wired network access of one computer with wireless clients connected to that soft AP.
These include design flaws in the Wi-Fi standard, affecting most devices, and programming errors in Wi-Fi products, making almost all Wi-Fi products vulnerable. The vulnerabilities impact all Wi-Fi security protocols, including WPA3 and WEP. Exploiting these flaws is complex but programming errors in Wi-Fi products are easier to exploit.
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
Slowloris is a type of denial of service attack tool which allows a single machine to take down another machine's web server with minimal bandwidth and side effects on unrelated services and ports. Slowloris tries to keep many connections to the target web server open and hold them open as long as possible.
A reverse connection is usually used to bypass firewall restrictions on open ports. [1] A firewall usually blocks incoming connections on closed ports, but does not block outgoing traffic . In a normal forward connection, a client connects to a server through the server's open port , but in the case of a reverse connection, the client opens the ...
In computer networking, port knocking is a method of externally opening ports on a firewall by generating a connection attempt on a set of prespecified closed ports. Once a correct sequence of connection attempts is received, the firewall rules are dynamically modified to allow the host which sent the connection attempts to connect over specific port(s).
