iOS jailbreaking is the use of a privilege escalation exploit to remove software restrictions imposed by Apple on devices running iOS and iOS-based [a] operating systems. It is typically done through a series of kernel patches.
The concept of a code cave is often employed by hackers and reverse engineers to execute arbitrary code in a compiled program. It can be a helpful method to make modifications to a compiled program in the example of including additional dialog boxes, variable modifications or even the removal of software key validation checks.
Secure coding is the practice of developing computer software in such a way that guards against the accidental introduction of security vulnerabilities.Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities. [1]
Cydia can be installed via third-party jailbreaking software such as the more recent applications unc0ver (iOS 11 – iOS 14), [23] Checkra1n for A7-A11 [Is in beta, iOS 12 – iOS 14 100% supported, other, newer, versions work but are experimental], [24] Chimera for A12 (iOS 12, Sileo as the default package manager instead of Cydia), [25 ...
In hacking, a shellcode is a small piece of code used as the payload in the exploitation of a software vulnerability.It is called "shellcode" because it typically starts a command shell from which the attacker can control the compromised machine, but any piece of code that performs a similar task can be called shellcode.
In 1945, the US discovered that Canberra–Moscow messages were being encrypted first using a code-book and then using a one-time pad. However, the one-time pad used was the same one used by Moscow for Washington, D.C.–Moscow messages. Combined with the fact that some of the Canberra–Moscow messages included known British government ...

Applications of Barker codes are found in radar, [17] mobile phone, [18] telemetry, [19] ultrasound imaging and testing, [20] [21] GPS, [22] and Wi-Fi. [23] Many of these technologies use DSSS. This technique incorporates Barker code to improve the received signal quality and improve security. [24] These codes also used in radio frequency ...
