It is a practical solution against any possible form of return-oriented programming. The solution eliminates all unaligned free-branch instructions (instructions like RET or CALL which attackers can use to change control flow) inside a binary executable, and protects the free-branch instructions from being used by an attacker.
Scripts to perform automated analysis with Ghidra can be written in Java or Python (via Jython), [8] [9] though this feature is extensible and support for other programming languages is available via community plugins. [10] Plugins adding new features to Ghidra itself can be developed using a Java-based extension framework. [11]
EternalBlue [5] is a computer exploit software developed by the U.S. National Security Agency (NSA). [6] It is based on a vulnerability in Microsoft Windows that allowed users to gain access to any number of computers connected to a network.
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 ...
Unlocking the bootloader allows installing and running unsigned code on a device, including user customized software. Operating outside the manufacturer specification might usually result in voiding any warranties and may make the device susceptible to data theft, as the integrity of the operating system (as intended by the manufacturer) can no longer be guaranteed.

The first contest in 2007 [1] was conceived and developed by Dragos Ruiu in response to his frustration with Apple Inc.'s lack of response [8] to the Month of Apple Bugs and the Month of Kernel Bugs, [9] as well as Apple's television commercials that trivialized the security built into the competing Windows operating system. [10]
This makes it possible for a penetration tester (or attacker) to compromise a whole Windows domain after compromising a single machine that was a member of that domain. Furthermore, the attack can be implemented instantaneously and without any requirement for expensive computing resources to carry out a brute force attack.
Software crack illustration. Software cracking (known as "breaking" mostly in the 1980s [1]) is an act of removing copy protection from a software. [2] Copy protection can be removed by applying a specific crack.
