An example of an IDN homograph attack; the Latin letters "e" and "a" are replaced with the Cyrillic letters "е" and "а".The internationalized domain name (IDN) homograph attack (sometimes written as homoglyph attack) is a method used by malicious parties to deceive computer users about what remote system they are communicating with, by exploiting the fact that many different characters look ...
Defacement is generally meant as a kind of electronic graffiti and, like other forms of vandalism, is used to spread messages by politically motivated "cyber protesters" or hacktivists. [1]
This means the Geffe generator is a very weak generator and should never be used to generate stream cipher keystreams. Note from the table above that agrees with the generator output 4 times out of 8—a 50% correlation. We cannot use this to brute force LFSR-1 independently of the others: the correct key will yield output that agrees with the ...
For example, on January 7, 2014, this method would generate the domain name intgmxdeadnxuyla.com, while the following day, it would return axwscwsslmiagfah.com.This simple example was in fact used by malware like CryptoLocker, before it switched to a more sophisticated variant.
The same image viewed by white, blue, green, and red lights reveals different hidden numbers. Steganography (/ ˌ s t ɛ ɡ ə ˈ n ɒ ɡ r ə f i / ⓘ STEG-ə-NOG-rə-fee) is the practice of representing information within another message or physical object, in such a manner that the presence of the concealed information would not be evident to an unsuspecting person's examination.
Spoofing is the act of deception or hoaxing. [2] URLs are the address of a resource (as a document or website) on the Internet that consists of a communications protocol followed by the name or address of a computer on the network and that often includes additional locating information (as directory and file names).

In cryptography, a keystream is a stream of random or pseudorandom characters that are combined with a plaintext message to produce an encrypted message (the ciphertext).. The "characters" in the keystream can be bits, bytes, numbers or actual characters like A-Z depending on the usage case.
In cryptography, a brute-force attack consists of an attacker submitting many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found.
