Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident related to a security breach at Microsoft involving the exploitation of a security feature on Windows devices has not been reported to have happened again within the same organization [136991]. (b) The article does not mention any similar incident happening at other organizations or with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase: The security issue with Microsoft, where hackers exploited a security feature on Windows devices by using standalone JavaScript files to bypass SmartScreen, can be attributed to a design flaw in the system development [136991]. (b) The software failure incident related to the operation phase: The exploitation of the security feature by hosting malicious websites, sending specially crafted URL files via email, or exploiting compromised websites can be considered failures introduced by the operation or misuse of the system [136991].
Boundary (Internal/External) within_system, outside_system (a) The software failure incident related to the security breach at Microsoft was primarily within the system. The hackers exploited a security feature within Windows devices by using standalone JavaScript files to bypass SmartScreen, a warning popup designed to appear when suspicious activity is being downloaded onto a Windows device [136991]. Microsoft's experts identified the issue and released a patch to fix the vulnerability during their December 2022 Patch Tuesday, addressing nearly 50 potentially dangerous issues with their software [136991].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in Article 136991 was due to non-human actions. Specifically, hackers exploited a security vulnerability in Microsoft's SmartScreen feature by using standalone JavaScript files to bypass the security measure [136991].
Dimension (Hardware/Software) software The software failure incident reported in Article 136991 was due to contributing factors originating in software. The security breach at Microsoft was caused by hackers exploiting a security feature bypass in Windows devices using standalone JavaScript files to override SmartScreen, a warning popup designed to appear when suspicious activity is being downloaded onto a Windows device [136991]. The issue was resolved by Microsoft with a software update during their December 2022 Patch Tuesday, where they patched nearly 50 potentially dangerous issues with their software [136991].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident reported in Article 136991 was malicious in nature. Hackers exploited a security vulnerability in Microsoft's Windows devices by bypassing the SmartScreen feature using standalone JavaScript files to trick users into downloading malicious content onto their devices [136991]. This security breach was a deliberate attempt by the hackers to override the warning popup and compromise the security of Windows users.
Intent (Poor/Accidental Decisions) poor_decisions The software failure incident related to the security breach at Microsoft was primarily due to poor decisions made by the hackers who exploited a security feature bypass on Windows devices [136991]. The hackers were able to bypass the SmartScreen warning popup by using standalone JavaScript files to trick users into downloading malicious content onto their devices. This indicates a deliberate and intentional effort to exploit a vulnerability in the system, rather than accidental decisions or mistakes leading to the failure.
Capability (Incompetence/Accidental) unknown (a) The software failure incident related to development incompetence is not explicitly mentioned in the provided article [136991]. (b) The software failure incident in the article [136991] was due to hackers exploiting a security vulnerability in Microsoft's Windows operating system. This incident was not accidental but a deliberate attempt by hackers to bypass the SmartScreen security feature using standalone JavaScript files to trick users into downloading malicious content onto their devices.
Duration temporary The software failure incident reported in Article 136991 was temporary. The incident involved a significant security breach in Microsoft's Windows devices due to hackers exploiting a security feature bypass. Microsoft was able to fix the issue during their December 2022 Patch Tuesday by releasing an update that addressed the vulnerability. This indicates that the failure was temporary and resolved through a software update [136991].
Behaviour omission, value, other (a) crash: The software failure incident in the article was not described as a crash where the system loses state and does not perform any of its intended functions [136991]. (b) omission: The security issue with Microsoft's SmartScreen feature allowed hackers to exploit a bypass, leading to the omission of the warning popup designed to appear when suspicious activity is being downloaded onto a Windows device [136991]. (c) timing: The software failure incident did not involve timing issues where the system performs its intended functions too late or too early [136991]. (d) value: The security issue with Microsoft's SmartScreen feature resulted in the system performing its intended functions incorrectly by allowing hackers to trick Windows users into downloading malicious content onto their devices [136991]. (e) byzantine: The software failure incident did not exhibit byzantine behavior where the system behaves erroneously with inconsistent responses and interactions [136991]. (f) other: The software failure incident involved a security breach where hackers exploited a vulnerability in Microsoft's SmartScreen feature to bypass the warning popup and trick users into downloading malicious content onto their devices [136991].
