Impacted Organization 1. Users of the photo-sharing community 500px were impacted by the software failure incident [81150].
Software Causes 1. The software cause of the failure incident was a breach in the system of the photo-sharing community 500px, leading to unauthorized access to personal data of users such as names, usernames, email addresses, and hashed passwords [81150].
Non-software Causes 1. Lack of adequate cybersecurity measures [81150] 2. Breach of system security protocols [81150] 3. Insufficient data protection practices [81150]
Impacts 1. Personal data of all 500px users was exposed, including first and last names, usernames, email addresses, and hashed passwords [81150]. 2. Additional user information such as birth date, local region, and gender provided during registration was also affected [81150]. 3. Users were required to reset their account passwords as a precautionary measure [81150].
Preventions 1. Implementing robust cybersecurity measures such as regular security audits, penetration testing, and intrusion detection systems could have potentially prevented the hack on 500px's system [81150].
Fixes 1. Implementing stronger security measures such as multi-factor authentication to prevent unauthorized access [81150]. 2. Conducting regular security audits and penetration testing to identify and address vulnerabilities in the system [81150]. 3. Enhancing user data protection by encrypting sensitive information stored in the database [81150]. 4. Providing timely notifications to users about security breaches and requiring password resets as a precautionary measure [81150].

Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident related to 500px has not happened again within the same organization as per the provided article [81150]. (b) The software failure incident related to a breach at 500px in July 2018 is not explicitly mentioned to have happened again at other organizations in the provided article [81150].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be attributed to the breach of the 500px system that exposed personal data on all users. The incident was a result of a hack that occurred in July 2018 but was only discovered in February 2019. This breach was a failure introduced during the system development or updates, leading to the exposure of user information such as names, usernames, email addresses, and hashed passwords [81150]. (b) The software failure incident related to the operation phase can be seen in the response of 500px to the breach. As a precautionary measure, 500px required all users to reset their account passwords, indicating that the failure was also influenced by the operation or misuse of the system. This action was taken to mitigate any potential risks to user accounts and data due to the breach [81150].
Boundary (Internal/External) within_system (a) The software failure incident reported in Article 81150 is within_system. The breach of 500px's system that exposed personal data on all users was a result of a hack that originated from within the system itself. The article mentions that user information such as names, usernames, email addresses, and hashed passwords were compromised due to the breach within the 500px system. Additionally, the company's engineers found no evidence of a recurrence of the issue within their platform, indicating that the failure was contained within the system [81150].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in Article 81150 was due to non-human actions, specifically a hack that exposed personal data of users on the 500px platform. The breach occurred in July 2018 and was discovered later, leading to the exposure of user information such as names, usernames, email addresses, and hashed passwords. This incident was not a result of human actions but rather a breach in the system's security [81150].
Dimension (Hardware/Software) software (a) The software failure incident reported in Article 81150 was not attributed to hardware issues. The incident was a result of a hack that exposed personal data of users on the photo-sharing platform 500px. The breach involved unauthorized access to user information such as names, email addresses, hashed passwords, and additional details provided during registration. The focus of the incident was on the security breach and the exposure of user data, indicating a software-related failure rather than a hardware-related one [81150].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident reported in Article 81150 was malicious in nature. The incident was a breach of 500px's system that exposed personal data of all its users. The hack resulted in the unauthorized access to user information such as names, usernames, email addresses, hashed passwords, and additional personal details if provided during registration. This breach was intentional and aimed at accessing sensitive user data without authorization, indicating a malicious objective [81150].
Intent (Poor/Accidental Decisions) poor_decisions (a) The software failure incident at 500px can be attributed to poor decisions made by the company. The incident occurred shortly after 500px announced a significant change in its platform by disabling the ability for users to freely share their photos under Creative Commons licenses. This decision was not well-received by many users, indicating that it may have contributed to the dissatisfaction and potentially motivated the hack that exposed personal data of all users [81150].
Capability (Incompetence/Accidental) accidental (a) The software failure incident related to development incompetence is not evident from the provided article. (b) The software failure incident related to accidental factors is evident in the article. The breach of 500px's system in July 2018 was discovered only recently, indicating that the exposure of personal data was not intentional but accidental. The article mentions that the hack yielded user information such as names, usernames, email addresses, and hashed passwords, indicating that the breach was not planned but rather a result of accidental security vulnerabilities [81150].
Duration permanent (a) The software failure incident in this case appears to be permanent as it was a breach that occurred in July 2018 and was only discovered in February 2019 [81150]. The breach exposed personal data of all users, including names, usernames, email addresses, hashed passwords, and additional information if provided during registration. The incident was not temporary but rather a significant breach that affected all users up to a certain date.
Behaviour omission, other (a) crash: The article does not mention a crash of the system where it lost state and did not perform any of its intended functions. (b) omission: The software failure incident in this case is related to a breach where personal data of users was exposed due to a hack. This can be considered an omission as the system failed to protect the users' personal information [81150]. (c) timing: The timing of the software failure incident is not relevant in this case. (d) value: The software failure incident does not involve the system performing its intended functions incorrectly. (e) byzantine: The software failure incident does not involve the system behaving erroneously with inconsistent responses and interactions. (f) other: The behavior of the software failure incident in this case is primarily related to a security breach leading to the exposure of personal data of users.

Consequence property (d) property: People's material goods, money, or data was impacted due to the software failure The software failure incident at 500px resulted in a breach of its system that exposed personal data of all its users, including information such as users' names, usernames, email addresses, hashed passwords, birth dates, local region, and gender information [81150]. As a precautionary measure, 500px required all users to reset their account passwords [81150]. The breach did not lead to the access of individual users' accounts or other personal data like credit card information, but it did impact the security and privacy of users' data stored on the platform [81150].
Domain information (a) The failed system in the reported incident was related to the information industry. The software failure incident occurred at the photo-sharing community 500px, which is a platform for users to share and license images [Article 81150].
