Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident having happened again at one_organization: - TaskRabbit experienced a cybersecurity incident, leading to the temporary shutdown of its app and website for investigation [70906]. (b) The software failure incident having happened again at multiple_organization: - There is no information in the provided article indicating that a similar incident has happened at other organizations.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the TaskRabbit cybersecurity incident mentioned in Article 70906. TaskRabbit had to temporarily take down its app and website to investigate a cybersecurity incident. This indicates a failure due to contributing factors introduced by system development or updates that led to a security breach, prompting the need for external cybersecurity experts to figure out what happened [70906]. (b) The software failure incident related to the operation phase is evident in the TaskRabbit incident as well. Users were advised to change their passwords if they used the same password on other sites or apps as they did for TaskRabbit, indicating a failure due to contributing factors introduced by the operation or misuse of the system [70906].
Boundary (Internal/External) within_system (a) within_system: The software failure incident reported in Article 70906 about TaskRabbit's cybersecurity incident seems to be within the system. TaskRabbit sent an alert to its users, informing them about the cybersecurity incident they were investigating. The company mentioned working with an outside cybersecurity firm and law enforcement to figure out what happened, indicating that the failure originated from within the system itself [70906].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident occurring due to non-human actions: - TaskRabbit experienced a cybersecurity incident that led to the app and website being temporarily taken down for investigation [70906]. - The incident involved a technical issue where TaskRabbit's website redirected users to a WordPress page showing the app's Github account, which was not intended behavior [70906]. - The URL of the WordPress page referenced an episode title from the show "Mr. Robot," indicating a non-human action in the form of a reference to hacking [70906]. (b) The software failure incident occurring due to human actions: - TaskRabbit advised its users to change passwords if they used the same password on other sites or apps as they did for TaskRabbit, suggesting a potential human action leading to security vulnerabilities [70906]. - The company mentioned working with an outside cybersecurity firm and law enforcement to investigate the incident, indicating the involvement of human actions in the response and resolution process [70906].
Dimension (Hardware/Software) software (a) The software failure incident reported in Article 70906 was related to cybersecurity, indicating a potential breach or attack on TaskRabbit's network. This incident does not seem to be attributed to hardware failure but rather to external cybersecurity threats or vulnerabilities in the software system [70906]. (b) The software failure incident in Article 70906 was specifically related to a cybersecurity incident affecting TaskRabbit's app and website. The company mentioned working with an outside cybersecurity firm to investigate the issue, indicating that the failure originated in the software system due to potential security vulnerabilities or breaches [70906].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident reported in Article 70906 is related to a malicious objective. TaskRabbit reported a cybersecurity incident and mentioned working with an outside cybersecurity firm and law enforcement to investigate what happened. The incident led to the temporary shutdown of the app and website, with recommendations for users to change passwords used on other sites or apps. Additionally, the incident involved a redirection of TaskRabbit's website to a WordPress page showing the app's Github account, which has since been taken down. The URL of the page referenced an episode title from a show about hackers, indicating a potentially malicious intent behind the incident [70906].
Intent (Poor/Accidental Decisions) poor_decisions (a) The software failure incident reported in Article 70906 was related to poor_decisions. TaskRabbit experienced a cybersecurity incident that led to the temporary shutdown of their app and website. The incident prompted the company to advise users to change their passwords if they used the same password on other sites or apps. Additionally, the incident caused inconvenience to clients and Taskers, leading to the rescheduling of uncompleted tasks and compensation for affected Taskers. The redirection of TaskRabbit's website to a WordPress page showing the app's Github account also indicated a security lapse, further highlighting the impact of poor decisions in managing cybersecurity [70906].
Capability (Incompetence/Accidental) accidental (a) The software failure incident related to development incompetence is not explicitly mentioned in the provided article [70906]. (b) The software failure incident related to accidental factors is evident in the article as TaskRabbit experienced a cybersecurity incident that led to the temporary shutdown of the app and website. The incident prompted the company to work with an outside cybersecurity firm and law enforcement to investigate what happened. Additionally, users were advised to change their passwords if they used the same password on other sites or apps as they did for TaskRabbit, indicating a breach that occurred accidentally [70906].
Duration temporary (a) The software failure incident in the TaskRabbit case was temporary. The article mentions that the app and website were temporarily taken down while the company was investigating the cybersecurity incident. TaskRabbit also assured users that they would reschedule any uncompleted tasks as soon as possible and compensate Taskers who were unable to complete their tasks [70906].
Behaviour crash, other (a) crash: The software failure incident in the TaskRabbit article can be categorized as a crash. The app and website were temporarily taken down as an immediate precaution while the company investigated the cybersecurity incident, indicating a failure due to the system losing state and not performing its intended functions [70906]. (b) omission: There is no specific mention of the software failure incident being related to omission in the TaskRabbit article [70906]. (c) timing: The timing of the software failure incident is not explicitly described in the TaskRabbit article [70906]. (d) value: The software failure incident in the TaskRabbit article does not involve the system performing its intended functions incorrectly, so it does not fall under the value category [70906]. (e) byzantine: The software failure incident in the TaskRabbit article does not exhibit behavior related to the system behaving erroneously with inconsistent responses and interactions, so it does not align with the byzantine category [70906]. (f) other: The other behavior exhibited in the software failure incident is the system redirecting users to a WordPress page showing the app's Github account, which is not a typical response during a cybersecurity incident. This behavior can be categorized as "unusual redirection" [70906].
