| Recurring |
unknown |
(a) The software failure incident related to the jailbreak affecting iOS devices with Apple's A5 to A11 chips is specific to Apple products. This incident does not mention similar incidents happening again within the same organization (Apple) or with its products and services. Therefore, there is no indication of a recurring software failure incident within the same organization based on the provided article [90260].
(b) The article does not mention any similar incidents happening at other organizations or with their products and services. Hence, there is no information provided about the software failure incident occurring again at multiple organizations based on the given article [90260]. |
| Phase (Design/Operation) |
design |
(a) The software failure incident in the article is related to the design phase. The jailbreak exploit called checkm8 takes advantage of a bootrom vulnerability in iOS devices, allowing owners to have full control over their iPhones. This exploit targets a security flaw in the code that runs on iOS devices during boot up, indicating a failure introduced by system development or system updates [90260].
(b) The software failure incident in the article is not related to the operation phase or misuse of the system. |
| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident described in the article is related to a jailbreak exploit affecting iOS devices with Apple's A5 to A11 chips. The exploit, named checkm8, takes advantage of a bootrom vulnerability within the iOS devices to give owners full control over their iPhones. This indicates that the failure originated from within the system itself, specifically from the vulnerability present in the bootrom of the affected devices [90260].
(b) outside_system: There is no information in the article suggesting that the software failure incident was caused by contributing factors originating from outside the system. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident in this case is related to non-human_actions, specifically a bootrom vulnerability exploited by the checkm8 jailbreak affecting iOS devices with Apple's A5 to A11 chips [90260]. This exploit allows owners to gain full control over their iPhones without requiring any human intervention in the actual software code.
(b) The software failure incident is not related to human_actions in terms of introducing contributing factors by human actions. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident in this case is related to hardware. The jailbreak exploit called checkm8 takes advantage of a bootrom vulnerability in the hardware of iOS devices with Apple's A5 to A11 chips. This hardware vulnerability allows owners to gain full control over their iPhones, bypassing Apple's security measures [90260]. Fixing this type of exploit would require physical modifications to an iPhone's chips, indicating that the failure originates in the hardware rather than the software. |
| Objective (Malicious/Non-malicious) |
malicious |
(a) The software failure incident described in the article is malicious in nature. It involves a new jailbreak exploit called checkm8, which takes advantage of a bootrom vulnerability to give owners full control over their iPhones. The exploit was discovered by a security researcher named axi0mX, who described the jailbreak as permanent and unpatchable. Jailbreaking an iPhone allows customization and running unsupported apps, but Apple warns that such unauthorized modifications can lead to security vulnerabilities, device crashes, and data loss. The exploit targets a security flaw in the code that runs on iOS devices during boot up, indicating a deliberate attempt to bypass Apple's security measures [90260]. |
| Intent (Poor/Accidental Decisions) |
poor_decisions |
The software failure incident described in the article is related to a jailbreak exploit called checkm8 affecting iOS devices with Apple's A5 to A11 chips. The intent behind this software failure incident can be categorized as follows:
(a) poor_decisions: The jailbreak exploit was intentionally developed by a security researcher named axi0mX to give owners full control over their iPhones. This deliberate decision to create the exploit can be seen as a poor decision from Apple's perspective as it allows unauthorized modifications to iOS, leading to security vulnerabilities, device crashes, and data loss [90260].
(b) accidental_decisions: There is no indication in the article that the software failure incident was a result of accidental decisions or unintended mistakes. The exploit was purposefully created to provide users with the ability to customize their iOS devices and run unsupported apps, indicating a deliberate action rather than an accidental decision [90260].
Therefore, based on the information provided in the article, the intent of the software failure incident is more aligned with poor_decisions rather than accidental_decisions. |
| Capability (Incompetence/Accidental) |
unknown |
(a) The software failure incident related to development incompetence is not applicable in this case as the reported incident is about a new jailbreak exploit called checkm8 affecting iOS devices with Apple's A5 to A11 chips. The exploit was discovered by a security researcher and was described as permanent and unpatchable, indicating a high level of technical competence in identifying and exploiting the vulnerability [90260].
(b) The software failure incident related to an accidental cause is not explicitly mentioned in the article. The incident primarily revolves around the intentional development of a jailbreak exploit by a security researcher to gain full control over iPhones with specific chips, rather than an accidental software failure. |
| Duration |
permanent |
(a) The software failure incident in this case is considered permanent. The jailbreak exploit using checkm8 is described as permanent and unpatchable by the security researcher axi0mX who discovered it [90260]. This means that the exploit gives owners full control over their iPhones indefinitely, as it takes advantage of a bootrom vulnerability that cannot be easily fixed without physical modifications to the iPhone's chips. |
| Behaviour |
crash, other |
(a) crash: The article mentions that jailbreaking an iPhone can lead to "device crashes" as one of the potential consequences of unauthorized modifications to iOS [90260].
(b) omission: The article does not specifically mention any instances of the system omitting to perform its intended functions.
(c) timing: The article does not mention any instances of the system performing its intended functions too late or too early.
(d) value: The article does not mention any instances of the system performing its intended functions incorrectly.
(e) byzantine: The article does not mention any instances of the system behaving erroneously with inconsistent responses and interactions.
(f) other: The behavior of the software failure incident in this case is related to unauthorized modifications through jailbreaking, which can lead to security vulnerabilities, device crashes, and data loss according to Apple [90260]. |
