Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident of a bug causing iPhones to crash has happened before with Apple's products. The article mentions previous instances of strange links and bugs crashing Apple devices as pranks, such as a link crashing Safari and a text message causing iPhones to crash without being opened [49817]. (b) The software failure incident of a bug causing iPhones to crash has also affected Android devices and computers, although to a lesser extent. This indicates that similar incidents have occurred with products from multiple organizations [49817].
Phase (Design/Operation) design (a) The software failure incident described in the article is related to the design phase. The incident is caused by a bug in the media handling functions of iOS, affecting various versions of the operating system (iOS 5 and above) and devices (iPhone 4 to iPhone 7). This bug is triggered by watching a specific video that slows down the iPhone until it crashes, requiring a forced reboot to recover functionality. The issue seems to be inherent in the design of the iOS media handling functions, leading to the system lockup after playing the video [49817]. (b) The software failure incident is not related to the operation phase or misuse of the system. The incident is triggered by watching a specific video, and users are not intentionally misusing the system. The failure is not caused by user error or misuse but rather by a bug in the system's design related to media handling functions [49817].
Boundary (Internal/External) within_system (a) within_system: The software failure incident described in the article is within the system. The issue is related to a bug in the media handling functions of iOS, affecting various versions of the operating system (iOS 5 and above) and devices (iPhone 4 to iPhone 7). The bug causes the iPhone to slow down and eventually crash after playing a specific video from the Miaopai app. Users need to perform a soft reset or forced reboot to recover the functionality of their iPhones [49817]. (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 Article 49817 is related to non-human_actions. The incident involves a video link that, when watched, triggers a bug in the media handling functions of iOS, causing iPhones to slow down and eventually crash without any direct human involvement. The bug affects various versions of iOS and iPhone models, with the lockup requiring a forced reboot to recover functionality. This type of failure is initiated by the specific characteristics of the video and the way iOS processes media content, rather than being intentionally caused by human actions [49817]. (b) Additionally, the article mentions previous instances of software bugs and pranks that have caused iPhones to crash, such as the "effective power" text message and a link that crashed Safari. These incidents were also examples of software failures triggered by non-human actions, as they exploited vulnerabilities or bugs in the software itself rather than being directly caused by human actions [49817].
Dimension (Hardware/Software) hardware, software (a) The software failure incident described in the article is primarily related to hardware. The issue involves a video link that, when watched on an iPhone, causes the device to slow down and eventually crash, requiring a forced reboot to recover functionality. The bug seems to be related to the media handling functions of iOS and affects various iPhone models from iPhone 4 to iPhone 7, with older devices experiencing faster lockups. The article mentions specific steps to perform a soft reset or forced reboot on different iPhone models to address the issue, indicating that the problem is more hardware-related in terms of device behavior and response to the triggering video link. (b) The software failure incident also has a significant software component. The bug in question appears to be related to the media handling functions of iOS, indicating a software issue within the operating system that allows the video link to cause the iPhone to lock up and crash. The article highlights that the bug affects iOS versions as far back as iOS 5, suggesting a long-standing software vulnerability within the operating system. Additionally, the history of similar crash bugs affecting iPhones, such as the "effective power" text message prank, further emphasizes the software-related nature of the incident.
Objective (Malicious/Non-malicious) malicious (a) The software failure incident described in the article is malicious in nature. It involves a video link that, when watched, intentionally slows down iPhones until they crash, requiring a forced reboot to recover [Article 49817]. This incident is part of a prank where the video is designed to cause disruption and inconvenience to iPhone users, indicating malicious intent behind the software failure.
Intent (Poor/Accidental Decisions) poor_decisions (a) The intent of the software failure incident related to poor_decisions: - The incident described in the article seems to be intentional, as it involves a video link that, when watched, deliberately slows down iPhones until they crash. This can be seen as a prank or malicious act aimed at disrupting the normal functioning of the devices [49817]. (b) The intent of the software failure incident related to accidental_decisions: - There is no indication in the article that the software failure incident was a result of accidental decisions. The deliberate nature of the video link causing iPhones to crash suggests a more intentional act rather than accidental decisions [49817].
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident related to development incompetence is evident in the article as it describes a video link that, when watched, slows down any iPhone until it crashes. This issue affects various versions of iOS, including older ones like iOS 5, and devices ranging from the iPhone 4 to the iPhone 7. The bug seems to involve the media handling functions of iOS, indicating a flaw in the software development process that allowed such a vulnerability to exist [49817]. (b) The software failure incident related to accidental factors is also present in the article. The article mentions that the bug causing the iPhone to crash is being used as a prank, indicating that the initial creation of the video link may have been accidental or unintended. Additionally, the article highlights previous instances of similar crash bugs affecting iPhones, such as the "effective power" text message, which further suggests that these incidents may not have been intentional but rather accidental in nature [49817].
Duration temporary The software failure incident described in Article 49817 is temporary. The article mentions that the video link causes the iPhone to slow down and eventually crash, requiring a forced reboot to recover the device's functionality. The lockup is not permanent, as it can be resolved by performing a soft reset or forced reboot [49817].
Behaviour crash (a) The software failure incident described in the article is a crash. The video link mentioned in the article causes iPhones to slow down and eventually crash, requiring a forced reboot to recover the device's functionality [49817]. (b) The software failure incident does not involve omission as the system is not omitting to perform its intended functions at an instance(s) but rather crashing due to the video link [49817]. (c) The software failure incident does not involve timing issues as the system is not performing its intended functions too late or too early but rather crashing after playing the video link [49817]. (d) The software failure incident does not involve value issues as the system is not performing its intended functions incorrectly but rather crashing due to the video link [49817]. (e) The software failure incident does not exhibit byzantine behavior as there is no mention of inconsistent responses or interactions; it simply causes the iPhone to crash [49817]. (f) The other behavior exhibited by the software failure incident is that it leads to the system losing state and not performing any of its intended functions, which aligns with the definition of a crash [49817].
