Customers who downloaded the corrupted applications experienced persistent crashes, leading to a poor user experience and potential loss of trust in the App Store [13365].
Preventions To prevent the software failure incident of binary corruption in Apple's App Store, the following measures could have been taken: 1. Implement robust testing procedures: Conduct thorough testing of updates before releasing them to ensure the integrity of the binaries and prevent corruption [13365]. 2. Enhance version control mechanisms: Implement strict version control practices to track changes and ensure that updates are properly managed to avoid introducing corruption issues [13365]. 3. Improve communication with developers: Establish clear communication channels with developers to promptly address any reported issues and collaborate on resolving problems efficiently [13365]. 4. Enhance monitoring and alert systems: Implement monitoring tools to detect anomalies in the App Store's operation, such as corrupted downloads, and set up alerts to notify the team of potential issues in real-time [13365].
Fixes 1. Restoring the previous version from a Time Machine backup [13365]

Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident of binary corruption affecting applications in Apple's App Store has happened again within the same organization. The incident caused applications to be downloaded in a corrupted state, leading to persistent crashes upon launch. Apple acknowledged the issue and is working to resolve it, indicating a recurrence of a similar problem within their services [13365]. (b) There is no information in the provided article about the software failure incident happening again at multiple organizations.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the article where it mentions that applications for recently updated programs in Apple's App Store were corrupted, leading to persistent crashes when launched. This indicates a failure due to contributing factors introduced by system updates or procedures to operate the system [13365]. (b) The software failure incident related to the operation phase is evident in the article where it states that customers experiencing crashing problems were instructed to contact Apple for assistance. If the issue was determined to lie with the app and not with the App Store or the customer's account, Apple would contact the developer to resolve the issue. This shows a failure due to contributing factors introduced by the operation or misuse of the system [13365].
Boundary (Internal/External) within_system (a) The software failure incident reported in Article 13365 is within_system. The issue of binary corruption affecting applications in Apple's App Store was acknowledged by Apple, and they mentioned working on resolving the issue. Developers were able to contact Apple to have problems with their updates fixed, indicating that the root cause of the problem was within the system itself [13365].
Nature (Human/Non-human) non-human_actions (a) The software failure incident occurring due to non-human actions: The software failure incident in the Apple App Store was related to a binary corruption problem where applications being downloaded were not intact and would crash when launched. This issue affected both Apple's iOS and Mac App stores, resulting in persistent crashes when launching recently updated programs. Apple acknowledged the issue and mentioned that they were working on resolving it, indicating that the problem was due to factors introduced without human participation [13365]. (b) The software failure incident occurring due to human actions: There is no specific mention in the article about the software failure incident being caused by contributing factors introduced by human actions. Therefore, it is unknown if human actions played a role in this particular incident.
Dimension (Hardware/Software) software (a) The software failure incident related to hardware: - The article does not mention any hardware-related issues contributing to the software failure incident. It primarily focuses on the binary corruption problem affecting applications in Apple's App Store [13365]. (b) The software failure incident related to software: - The software failure incident is directly related to software issues, specifically a binary corruption problem in Apple's App Store that caused applications to be downloaded in a corrupted state, leading to persistent crashes when launched [13365].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in the article is non-malicious. The issue was related to binary corruption problems in Apple's App Store, causing applications to crash when launched. Apple acknowledged the problem and was working to correct it. Developers were able to contact Apple to have their updates fixed, and Apple was actively communicating with developers and customers to address the issue. There was no indication in the article that the failure was due to malicious intent; instead, it seemed to be a technical issue that Apple was working to resolve [13365].
Intent (Poor/Accidental Decisions) accidental_decisions (a) The software failure incident related to the binary corruption problem in Apple's App Store does not indicate poor decisions as the intent behind the issue. Instead, it seems to be an accidental decision or mistake leading to the problem. Apple acknowledged the issue, mentioned they are working on resolving it, and provided instructions for developers and customers to address the crashing problem. There is no indication in the article that the failure was a result of poor decisions made intentionally. [Cited Article: 13365]
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident related to development incompetence is evident in the article as it mentions a binary corruption problem affecting applications in Apple's App Store. The issue caused applications to be downloaded in a corrupted state, leading to persistent crashes upon launch. This indicates a failure in ensuring the integrity of the applications during the download process, which could be attributed to a lack of professional competence in handling the update mechanism [13365]. (b) The software failure incident related to accidental factors is also present in the article. Apple acknowledged the issue and mentioned that they are working on resolving it. The fact that the problem affected both iOS and Mac App stores and was not intentional but rather a result of corrupted downloads suggests that the incident was accidental in nature [13365].
Duration temporary The software failure incident reported in Article 13365 can be categorized as a temporary failure. The article mentions that the problem with binary corruption affecting applications in Apple's App Store has been occurring since earlier that week. Apple has acknowledged the issue, is actively working on resolving it, and has provided instructions for developers on how to address the issue with their updates. Additionally, Apple has contacted developers to notify them about the problem and the steps to take if customers experience crashing problems. This indicates that the software failure incident is temporary and is being actively addressed by Apple to correct the issue. [13365]
Behaviour value (a) The software failure incident described in the article is related to crashes. Applications downloaded from Apple's App Store were found to be corrupted, leading to persistent crashes when launched [13365]. (d) The value of the software failure incident is that the system was performing its intended functions incorrectly, resulting in crashes upon launching the applications [13365].
