Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident has happened again at Sprint. In addition to the recent data breach through a Samsung website, Sprint was also breached via its Boost Mobile prepaid subsidiary in the past. Hackers used Boost phone numbers and Boost.com PIN codes to gain access to Sprint accounts [87207]. (b) There is no information in the provided article indicating that a similar incident has happened at other organizations or with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident in Article 87207 can be attributed to the design phase. The breach occurred through the Samsung "add a line" website, indicating a vulnerability in the design or implementation of that specific feature. Hackers were able to exploit this design flaw to gain unauthorized access to customer accounts, leading to the data breach [87207]. (b) Additionally, the incident also involved factors related to the operation phase. Hackers used Boost phone numbers and Boost.com PIN codes to gain access to Sprint accounts, suggesting that the misuse or exploitation of operational procedures played a role in the breach. Sprint took action to secure all accounts and notified customers to reset their PINs as a precaution against further unauthorized access [87207].
Boundary (Internal/External) within_system, outside_system (a) The software failure incident reported in the article is primarily within_system. The breach occurred through the Samsung "add a line" website, indicating a vulnerability within Sprint's system that allowed hackers to access customer accounts. Sprint took action to secure all accounts and notified customers of a PIN reset to mitigate the impact of the breach [87207]. (b) The software failure incident also involved outside_system factors as hackers used Boost phone numbers and Boost.com PIN codes to gain access to Sprint accounts. This indicates that external factors, such as compromised information from Boost Mobile, contributed to the breach [87207].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in this case occurred due to non-human actions, specifically a data breach caused by hackers breaking into customer accounts through a Samsung website [87207]. The breach resulted in the unauthorized access to customer information such as names, addresses, phone numbers, account details, device information, and more. The breach was not attributed to any human error or action but rather to external malicious actors exploiting vulnerabilities in the system.
Dimension (Hardware/Software) software (a) The software failure incident in this case was not directly attributed to hardware issues. The breach occurred through a Samsung website, indicating that the contributing factors originated in the software system of the website rather than hardware components [87207]. (b) The software failure incident was primarily due to contributing factors originating in software. The breach was facilitated through the Samsung "add a line" website, indicating a vulnerability or flaw in the software system that allowed hackers to access customer accounts and sensitive information [87207].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident in this case is malicious. Hackers broke into customer accounts through a Samsung website, resulting in a data breach affecting Sprint customers. The breach included sensitive information such as first and last names, billing addresses, phone numbers, subscriber IDs, account numbers, device details, and more. The hackers accessed this information with the intent to potentially commit fraud or identity theft [87207].
Intent (Poor/Accidental Decisions) poor_decisions, accidental_decisions (a) The software failure incident related to the data breach at Sprint appears to be more aligned with poor_decisions. The breach occurred through the Samsung "add a line" website, indicating a vulnerability in the system that allowed hackers to access customer accounts. Sprint confirmed that hackers were able to obtain sensitive information such as first and last names, billing address, phone numbers, subscriber IDs, account numbers, and more. This breach highlights a potential security flaw in the system, possibly due to poor decisions in the implementation or maintenance of the website's security measures [87207]. (b) Additionally, the incident involving the breach via Sprint's Boost Mobile prepaid subsidiary also suggests accidental_decisions. Hackers used Boost phone numbers and Boost.com PIN codes to gain access to Sprint accounts, indicating a potential oversight or unintended consequence of how the systems were interconnected. While credit card and social security numbers were encrypted and not compromised, the exposure of customers' account Personal Identification Numbers (PINs) raises concerns about the security measures in place and the potential unintended consequences of system design or integration decisions [87207].
Capability (Incompetence/Accidental) accidental (a) The software failure incident related to development incompetence is not explicitly mentioned in the provided article. Therefore, it is unknown if the incident was due to factors introduced by lack of professional competence. (b) The software failure incident related to accidental factors is evident in the article. The breach into Sprint customer accounts through a Samsung website was reported as a hack that occurred on June 22. The breach included details like first and last name, billing address, phone number, subscriber ID, account number, device type, device ID, monthly charges, account creation date, upgrade eligibility, and add-on services. Sprint mentioned that no other information that could create a substantial risk of fraud or identity theft was acquired. Additionally, Sprint notified customers of a PIN reset on June 25 as a precaution. The breach was described as a result of hackers gaining access to Sprint accounts using Boost phone numbers and Boost.com PIN codes. It is indicated that the breach was accidental and not due to intentional actions by the users [87207].
Duration temporary The software failure incident reported in the article was temporary. The breach occurred on June 22, and Sprint took action by notifying customers on June 25 of a PIN reset as a precautionary measure [87207]. This indicates that the breach was not a permanent failure but rather a temporary incident that was addressed promptly by the company.
