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] Another type of approach is password spraying ...
A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). [ 2] Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the ...
Domain hijacking. Domain hijacking or domain theft is the act of changing the registration of a domain name without the permission of its original registrant, or by abuse of privileges on domain hosting and registrar software systems. [ 1]
Spoofing attack. In the context of information security, and especially network security, a spoofing attack is a situation in which a person or program successfully identifies as another by falsifying data, to gain an illegitimate advantage. [ 1]
Typosquatting. An incorrectly entered URL could lead to a website operated by a cybersquatter. Typosquatting, also called URL hijacking, a sting site, a cousin domain, or a fake URL, is a form of cybersquatting, and possibly brandjacking which relies on mistakes such as typos made by Internet users when inputting a website address into a web ...
DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver 's cache, causing the name server to return an incorrect result record, e.g. an IP address. This results in traffic being diverted to any computer that the attacker chooses.
It allowed the user name, domain name, and password hashes cached in memory by the Local Security Authority to be changed at runtime after a user was authenticated — this made it possible to 'pass the hash' using standard Windows applications, and thereby to undermine fundamental authentication mechanisms built into the operating system.
ProPublica explicitly referenced the existence of Facebook's .onion site when they started their own onion service. [5] The site also makes it easier for Facebook to differentiate between accounts that have been caught up in a botnet and those that legitimately access Facebook through Tor. [6]
