Privilege escalation is the act of exploiting a bug, a design flaw, or a configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user. The result is that an application with more privileges than intended by the application developer or system administrator can perform unauthorized actions.
The iPod Touch is a discontinued line of iOS-based mobile devices designed and marketed by Apple Inc. with a touchscreen-controlled user interface. As with other iPod models, the iPod Touch can be used as a portable media player and a handheld gaming device, but can also be used as a digital camera, a web browser, for email and messaging. It is nearly identical in design to the iPhone, and can run most iPhone third-party apps from the App Store, but it connects to the internet only through Wi-Fi and uses no cellular network data since it lacks a cellular modem.
iOS is a mobile operating system developed by Apple Inc. exclusively for its hardware. It is the operating system that powers many of the company's mobile devices, including the iPhone; the term also includes the system software for iPads as well as on the iPod Touch devices. It is the world's second-most widely installed mobile operating system, after Android. It is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. It is proprietary software, although some parts of it are open source under the Apple Public Source License and other licenses.
SpringBoard is the standard application that manages the iPhone's home screen. Other tasks include starting WindowServer, launching and bootstrapping applications and setting some of the device's settings on startup.
On Apple devices running iOS and iOS-based operating systems, jailbreaking is the use of a privilege escalation exploit to remove software restrictions imposed by the manufacturer. Typically it is done through a series of kernel patches. A jailbroken device permits root access within the operating system and provides the right to install software unavailable through the App Store. Different devices and versions are exploited with a variety of tools. Apple views jailbreaking as a violation of the end-user license agreement and strongly cautions device owners not to try to achieve root access through the exploitation of vulnerabilities.
Cydia is a graphical user interface of APT for iOS. It enables a user to find and install software not authorized by Apple on jailbroken iPhones, iPads and iPod Touch devices. It also refers to digital distribution platform for software on iOS accessed through Cydia software. Most of the software packages available through Cydia are free of charge, although some require purchasing.
A mobile development framework is a software framework that is designed to support mobile app development. It is a software library that provides a fundamental structure to support the development of applications for a specific environment.
Icy is a discontinued package manager for jailbroken iPhone and iPod Touch, originally created and maintained by Ripdev, which allows users to browse and download mobile apps from a range of sources. Most apps were available to download for free, with some requiring purchase after downloading, including other software created by Ripdev, such as Kate. Apps are downloaded directly to iPhone or iPod Touch and are generally located in the /Applications/ directory, in the same place where "Apple native" apps are located.
A .ipa file is an iOS and iPadOS application archive file which stores an iOS/iPadOS app. Each .ipa file includes a binary and can only be installed on an iOS, iPadOS, or ARM-based macOS device. Files with the .ipa extension can be uncompressed by changing the extension to .zip and unzipping. This is only recommended when editing the app itself. Some ipa’s will not have a .app file.
Jay Ryan Freeman is an American businessman and software engineer. He is known for creating the Cydia software application and related software for jailbroken iOS—a modified version of Apple's iOS that allows for the installation and customization of software outside of the regulation imposed by the App Store system.
In computing, a SHSH blob is a digital signature that Apple generates and uses to personalize IPSW firmware files for each iOS device. SHSH blobs are part of Apple's protocol designed to ensure that only trusted software is installed on the device, generally only allowing the newest iOS version to be installable. Apple's public name for this process is System Software Authorization. The term “SHSH blob” is unofficial and based on abbreviations for signed hash and binary large object. An alternative term, ECID SHSH, refers to the device's ECID, a unique identification number embedded in its hardware)
JailbreakMe is a series of jailbreaks for Apple's iOS mobile operating system that took advantage of flaws in the Safari browser on the device, providing an immediate one-step jailbreak, unlike more common jailbreaks, such as Blackra1n and redsn0w, that require plugging the device into a computer and running the jailbreaking software from the desktop. JailbreakMe included Cydia, a package management interface that serves as an alternative to the App Store. Although it does not support modern devices, it can still be used and the site is up.

Evasi0n,, is a untethered jailbreak program for iOS 6.0 - 6.1.2 and for iOS 7.0 - 7.0.6. It is known for a portable code base and minimal use of arbitrary code execution. More than seven million copies of Evasi0n were downloaded in the first four days after release. It was released on 4 February 2013. Four of the six exploits used were patched by Apple on 18 March 2013 with the release of iOS 6.1.3. On 22 December 2013, the evad3rs released a new version of evasi0n that supports iOS 7.x, known as evasi0n7. One major exploit used by this jailbreak was patched by Apple with the 4th beta of iOS 7.1 and two more with beta 5. The final release of iOS 7.1 fixed all the exploits used by evasi0n7.
The Pangu Team, is a Chinese programming team in the iOS community that developed the Pangu jailbreaking tools. These are tools that assist users in bypassing device restrictions and enabling root access to the iOS operating system. This permits the user to install applications and customizations typically unavailable through the official iOS App Store.
Android Runtime for Chrome (ARC) is a compatibility layer and sandboxing technology for running Android applications on desktop and laptop computers in an isolated environment. It allows applications to be safely run from a web browser, independent of user operating system, at near-native speeds.
