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 ...

In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
The core technology, Superfish VisualDiscovery, is installed as a man-in-the-middle proxy on some Lenovo laptops. It injects advertising into results from Internet search engines; it also intercepts encrypted (SSL/TLS) connections. [7] [29] In 2014, Superfish released new apps based on its image search technology.
Downfall, known as Gather Data Sampling (GDS) by Intel, [1] is a computer security vulnerability found in 6th through 11th generations of consumer and 1st through 4th generations of Xeon Intel x86-64 microprocessors. [2]
Many ISPs register the client's MAC address for service and billing services. [3] Since MAC addresses are unique and hard-coded on network interface controller (NIC) cards, [1] when the client wants to connect a new device or change an existing one, the ISP will detect different MAC addresses and might not grant Internet access to those new devices.
