Software Taxonomy of Faults

Category Option Rationale
Recurring unknown The provided article does not mention any previous incidents of a similar software failure happening again at Optus or at other organizations. Therefore, the information regarding the software failure incident happening again at one_organization or multiple_organization is unknown.
Phase (Design/Operation) design (a) The software failure incident in this case occurred due to a design-related factor introduced during system development. The breach happened when hackers were able to access sensitive customer information by breaking through Optus' firewall, indicating a vulnerability in the system's design [132375]. (b) The incident did not involve a failure due to operation or misuse of the system.
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident at Optus, where a massive cyber-attack resulted in the theft of customers' personal information, was primarily due to factors originating from within the system. The breach occurred when hackers were able to break through the company's firewall, indicating a vulnerability or weakness in Optus' internal cybersecurity measures [132375]. (b) outside_system: The external factors contributing to the software failure incident at Optus include the actions of the hackers believed to be working for a criminal or state-sponsored organization. These external actors targeted Optus' system from outside, exploiting vulnerabilities to gain unauthorized access to sensitive customer information [132375].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in this case occurred due to non-human actions, specifically a massive cyber-attack on Optus resulting in a data breach. The hackers, believed to be working for a criminal or state-sponsored organization, accessed sensitive customer information by breaking through the company's firewall [132375]. (b) The software failure incident was not directly caused by human actions but rather by the actions of hackers who breached the company's systems. However, human actions in terms of responding to the incident, such as Optus taking immediate action to block the attack, conducting an investigation, and engaging with relevant authorities and organizations, were crucial in managing the aftermath of the cyber-attack [132375].
Dimension (Hardware/Software) software (a) The software failure incident reported in Article 132375 was not attributed to hardware issues. The incident was a cyber-attack where hackers breached Optus' systems by breaking through the company's firewall, indicating a failure originating in software security measures rather than hardware components [132375].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident reported in Article 132375 is malicious in nature. The incident involved a massive cyber-attack on Optus, where hackers, believed to be working for a criminal or state-sponsored organization, breached the company's firewall to steal personal information of customers, including names, dates of birth, addresses, and contact details. The attack was intentional and aimed at accessing sensitive information for malicious purposes [132375].
Intent (Poor/Accidental Decisions) poor_decisions The software failure incident reported in Article 132375 is related to a cyber-attack on Optus, resulting in a massive data breach. The incident was caused by hackers breaking through the company's firewall, indicating a failure due to poor decisions in terms of cybersecurity measures and defenses [132375]. Additionally, the breach was described as a cyber-attack, suggesting that it was a deliberate and intentional act by the hackers, rather than an accidental failure [132375].
Capability (Incompetence/Accidental) accidental (a) The software failure incident reported in the article is not attributed to development incompetence. The incident is primarily described as a massive cyber-attack where hackers breached Optus' systems and stole personal information of customers. The breach was a result of hackers breaking through the company's firewall, indicating a deliberate and malicious attack rather than a failure due to incompetence in development [132375]. (b) The software failure incident is described as an accidental failure. The breach occurred when hackers, believed to be working for a criminal or state-sponsored organization, accessed sensitive information by breaking through the company's firewall. This indicates that the breach was not intentional or planned by the company but rather an accidental event caused by external malicious actors [132375].
Duration temporary The software failure incident reported in Article 132375 is not related to a temporary or permanent software failure. Instead, it is related to a cyber-attack where hackers breached Optus' systems and stole customers' personal information.
Behaviour other (a) crash: The software failure incident in the article does not involve a crash where the system loses state and does not perform any of its intended functions. (b) omission: The software failure incident does not involve omission where the system omits to perform its intended functions at an instance(s). (c) timing: The software failure incident does not involve timing issues where the system performs its intended functions correctly but too late or too early. (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 software failure incident in the article involves a cyber-attack where hackers accessed sensitive information by breaking through the company's firewall, resulting in the disclosure of customers' personal information [132375].
