greenpois0n is a name shared by a series of iOS jailbreaking tools developed by Chronic Dev Team (sometimes called the greenpois0n team [4] ) that use exploits to remove software restrictions on iPhones, iPads, iPod Touches, and Apple TVs. Greenpois0n's initial release in October 2010 jailbroke iOS 4.1, [1] and its second version in February 2011 jailbroke iOS 4.2.1 [6] as well as iOS 4.2.6 on CDMA iPhones. [7] The second generation of the tool, greenpois0n Absinthe, was developed with iPhone Dev Team members and jailbroke iOS 5.0.1 in January 2012 (providing the first jailbreak of the iPhone 4S), [4] [8] and a second version jailbroke iOS 5.1.1 in May 2012 (providing the first jailbreak of the third generation iPad). [9]
Jailbreaking enables root access to the iOS operating system, [10] allowing the installation of applications and customizations that are unavailable through the official App Store for iOS. [11] [12] Jailbreaking voids the device's warranty, [13] and Apple releases iOS updates to make jailbreaking more difficult. [14]
On October 12, 2010, Chronic Dev Team released Greenpois0n, a desktop-based tool for jailbreaking iOS 4.1 on iPhone 4, iPhone 3GS, iPod Touch third and fourth generation, and iPhone OS 3.2.2 on the iPad 1. [1] During its development, Apple released the second generation Apple TV, and Greenpois0n's developers reported that it could jailbreak the Apple TV as well. [15] [16] The developers announced plans to release it on October 10, but after news spread of another jailbreak developer, George Hotz, preparing to release a jailbreaking tool called limera1n that would perform a similar function with a different exploit, [17] the Greenpois0n developers delayed in order to integrate the limera1n exploit, [18] which supported more devices. [19] Using limera1n also meant that the original Greenpois0n exploit (SHAtter) could be saved for use in later jailbreaks. [20] Both SHAtter and limera1n are boot ROM exploits, which means they cannot be patched by iOS updates because bootROM code is embedded in iOS devices during manufacturing, and cannot be overwritten at any time. [1]
In February 2011, Chronic Dev Team released a new version of greenpois0n to jailbreak iOS 4.2.1 [6] and to jailbreak iOS 4.2.6 on the iPhone 4 CDMA (Verizon), [7] with desktop-based tools for OS X, Microsoft Windows, and Linux. [21] It provides an "untethered" jailbreak, which means that the jailbroken device can be rebooted into a jailbroken state without computer assistance or user input. [21] It supports iPad, iPhone, iPod Touch, [22] and Apple TV. [23] [24] Chronic Dev Team announced support for the newly released iPhone 4 CDMA before the devices were in stores. [25]
As of late 2011, Joshua Hill was described as a "head honcho" of Chronic-Dev Team, [26] and as a principal. [27] Other members, in addition to Hill, [28] in early 2012 included Cyril, and Nikias Bassen. [29]
Developers from Chronic Dev Team and iPhone Dev Team released greenpois0n Absinthe (known as just "Absinthe") in January 2012, a desktop-based tool (for OS X, Microsoft Windows, and Linux [30] ) to jailbreak the iPhone 4S for the first time and the iPad 2 for the second time, on iOS 5.0.1 for both devices and also iOS 5.0 for iPhone 4S. [4] [8] Absinthe provides an "untethered" jailbreak, which means that the patched device can be rebooted directly into a jailbroken state without computer assistance (or, as with a semi-untethered jailbreak, without requiring an application to be launched on the device following startup, in order to reactivate the jailbreak exploit). [14] It incorporated the untether exploit called Corona that pod2g had released in December for older iOS devices. [8] The Next Web said that the jailbreak took a long time to be released, and VentureBeat said Absinthe wasn't as easy to use as the earlier jailbreaking tool JailbreakMe. [31] [32] According to iPhone Dev Team, approximately one million devices were newly jailbroken in the three days after Absinthe's release. [12] [32] The developers called their joint effort the Jailbreak Dream Team, [30] which Apple credited in its document listing security patches in the subsequent version of iOS. [33]
In May 2012, developers from Chronic Dev Team and iPhone Dev Team released Absinthe 2.0 (for OS X, Windows, and Linux), which can jailbreak iOS 5.1.1 untethered on all iPhone, iPad, and iPod Touch models that support iOS 5.1.1, [13] including jailbreaking the third generation iPad for the first time. [9] They announced it at the Hack In The Box security conference in Amsterdam at the end of a presentation about the earlier Absinthe jailbreak, [10] [34] and it did not initially support a recently released model of iPad 2. [35] [36] According to Chronic Dev Team, approximately one million devices were jailbroken over the weekend after its Friday release. [37] PC World noted that devices jailbroken with tools such as Absinthe 2.0 can be a security concern for companies that have "bring your own device" policies. [38]
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 or user with more privileges than intended by the application developer or system administrator can perform unauthorized actions.
The iPhone is a line of smartphones developed and marketed by Apple that use the company's own iOS mobile operating system. The first-generation iPhone was announced by then–Apple CEO Steve Jobs on January 9, 2007. Since then, Apple has annually released new iPhone models and iOS versions. As of January 1, 2024, more than 2.3 billion iPhones have been sold, making Apple the largest vendor of mobile phones in 2023.
The iPod Touch is a discontinued line of iOS-based mobile devices designed and formerly 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, as it lacks a cellular modem.
iOS is a mobile operating system developed by Apple exclusively for its devices. It was unveiled in January 2007 for the first-generation iPhone, which launched in June 2007. Major versions of iOS are released annually; the current stable version, iOS 18, was released to the public on September 16, 2024.
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.
iOS is a mobile operating system developed by Apple Inc. and was first released as iPhone OS in June 2007, coinciding with the launch of the first generation iPhone. iPhone OS was renamed iOS following the release of the iPad, starting with iOS 4. With iOS 13, Apple began offering a separate operating system, iPadOS, for the iPad. iOS is also the foundation of the newer audioOS and tvOS, and shares some of its code with macOS. New iOS versions are released yearly, alongside new iPhone models. From the launch of the iPhone in 2007 until the launch of iPhone 4 in 2010, this occurred in June or July; since then, new major versions are usually released in September, with the exception of iOS 5, which released in October 2011. Since the launch of the iPhone in June 2007, there have been 18 major releases of iOS, with the current major version being iOS 18, released on September 16, 2024.
Absinthe is a distilled alcoholic beverage.
iOS jailbreaking is the use of a privilege escalation exploit to remove software restrictions imposed by Apple on devices running iOS and iOS-based operating systems. It is typically done through a series of kernel patches. A jailbroken device typically 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 the 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.
The iPad is a brand of iOS- and iPadOS-based tablet computers that are developed and marketed by Apple. The first-generation iPad was introduced on January 27, 2010. Since then, the iPad product line has been expanded to include the smaller iPad Mini, the lighter and thinner iPad Air, and the flagship iPad Pro models. As of 2022, over 670 million iPads have been sold, making Apple the largest vendor of tablet computers. Due to its popularity, the term "iPad" is sometimes used as a generic name for tablet computers.
Siri is a digital assistant purchased, developed, and popularized by Apple Inc., which included it in the iOS, iPadOS, watchOS, macOS, tvOS, audioOS, and visionOS operating systems. It uses voice queries, gesture based control, focus-tracking and a natural-language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Internet services. With continued use, it adapts to users' individual language usages, searches, and preferences, returning individualized results.
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 control the iOS versions that users can install on their iOS devices 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, the websites remain available for compatible devices.
The iPad 2 is a tablet developed and marketed by Apple Inc. Compared to the first iPad, as the second model in the iPad line, it gained a faster dual core A5 processor, a lighter build structure with a flat, rather than curved, back, and was the first iPad to feature VGA front-facing and 720p rear-facing cameras designed for FaceTime video calling.
The iPhone 4s is a smartphone that was developed and marketed by Apple Inc. It is the fifth generation of the iPhone, succeeding the iPhone 4 and preceding the iPhone 5. It was announced on October 4, 2011, at Apple's Cupertino campus, and was the final Apple product announced in the lifetime of former Apple CEO and co-founder Steve Jobs, who died the following day.
The iPad is a tablet computer developed and marketed by Apple Inc. It is the third device in the iPad line of tablets. It added a Retina Display, the new Apple A5X chip with a quad-core graphics processor, a 5-megapixel camera, HD 1080p video recording, voice dictation, and support for LTE networks in North America. It shipped with iOS 5, which provides a platform for audio-visual media, including electronic books, periodicals, films, music, computer games, presentations and web browsing.
evasi0n is a jailbreak program for iOS 6.0-6.1.2, released on 4 February 2013, made by the evad3rs team. An updated version for iOS 7.0-7.0.6, evasi0n7, was released on 22 December 2013. More than seven million copies of evasi0n were downloaded in the first four days after release. It is known for a portable code base and minimal use of arbitrary code execution.
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.
The iOS mobile operating system developed by Apple has had a wide range of bugs and security issues discovered throughout its lifespan, including security exploits discovered in most versions of the operating system related to the practice of jailbreaking, bypassing the user's lock screen, issues relating to battery drain, crash bugs encountered when sending photos or certain Unicode characters via text messages sent through the Messages application, and general bugs and security issues later fixed in newer versions of the operating system.
