Hydra can launch attacks on multiple targets at once using threads, called hydra heads. The tool keeps track of the threads using another structure, the hydra brain. Each target is attacked using a module that corresponds to a protocol(eg. if the target is an SSH server, the SSH module is used).
A modified version of build-to-host.m4 was included in the release tar file uploaded on GitHub, which extracts a script that performs the actual injection into liblzma. This modified m4 file was not present in the git repository; it was only available from tar files released by the maintainer separate from git. [ 4 ]
The term "phishing" is said to have been coined by Khan C. Smith, a well-known spammer and hacker, [51] and its first recorded mention was found in the hacking tool AOHell, which was released in 1994. AOHell allowed hackers to impersonate AOL staff and send instant messages to victims asking them to reveal their passwords.
The weak-key-generation vulnerability was promptly patched after it was reported, but any services still using keys that were generated by the old code remain vulnerable. A number of software packages now contain checks against a weak key blacklist to attempt to prevent use of any of these remaining weak keys, but researchers continue to find ...
Zeus is very difficult to detect even with up-to-date antivirus and other security software as it hides itself using stealth techniques. [5] It is considered that this is the primary reason why the Zeus malware then had become the largest botnet on the Internet: Damballa estimated that the malware infected 3.6 million PCs in the U.S. in 2009.

Anti-phishing software consists of computer programs that attempt to identify phishing content contained in websites, e-mail, or other forms used to accessing data (usually from the internet) [1] and block the content, usually with a warning to the user (and often an option to view the content regardless).
In cryptography, the key-recovery advantage (KR advantage) of a particular algorithm is a measure of how effective an algorithm can mount a key-recovery attack. Consequently, the maximum key-recovery advantage attainable by any algorithm with a fixed amount of computational resources is a measure of how difficult it is to recover a cipher's key.
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 ...
