Software Taxonomy of Faults

Category Option Rationale
Recurring multiple_organization (a) The software failure incident related to a ransomware attack on the Los Angeles Unified School District (LAUSD) is a unique incident specific to that organization as per the provided article [133299]. There is no mention of a similar incident happening before within the LAUSD. (b) The article mentions that a ransomware gang known as Vice Society has been disproportionately targeting the education sector with ransomware attacks, indicating that similar incidents have occurred at other organizations within the education sector [133299].
Phase (Design/Operation) design (a) The software failure incident in Article 133299 was related to the design phase, as it was a ransomware attack on the Los Angeles Unified School District's Information Technology systems. The attack was confirmed as an external cyber attack on their IT assets, indicating a failure due to contributing factors introduced by system development or updates [133299].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident in the Los Angeles Unified School District was caused by a ransomware attack on their Information Technology assets. The district detected unusual activity within its IT systems, confirming it as an external cyber attack. The attack was likely criminal in nature, and the district implemented a response protocol to mitigate disruptions, including access to email, computer systems, and applications [133299]. (b) outside_system: The incident originated beyond the district's borders, indicating that the attack came from outside the system. Additionally, the U.S. government agencies issued a public advisory mentioning that a ransomware gang known as Vice Society had been disproportionately targeting the education sector with ransomware attacks, indicating external threats to the system [133299].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in this case was due to non-human actions, specifically a ransomware attack on the Los Angeles Unified School District's Information Technology systems [133299]. The attack was confirmed as an external cyber attack on the district's assets, indicating that the failure was caused by factors introduced without human participation.
Dimension (Hardware/Software) software (a) The software failure incident in the Los Angeles Unified School District was not attributed to hardware issues but rather to an external cyber attack on their Information Technology assets, indicating a software-related failure [133299].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident in this case was malicious, as it was a ransomware attack targeting the Los Angeles Unified School District's Information Technology systems. The attack was confirmed to be an external cyber attack on the district's assets, indicating that it was intentional and aimed at causing disruption and potentially extracting ransom payments. The ransomware gang known as Vice Society was mentioned as disproportionately targeting the education sector with ransomware attacks, further highlighting the malicious nature of the incident [133299].
Intent (Poor/Accidental Decisions) poor_decisions The software failure incident reported in Article 133299 was a ransomware attack targeting the Los Angeles Unified School District's Information Technology systems. The incident was likely criminal in nature, as mentioned in the district's statement. The attack was described as originating beyond the district's borders, indicating that it was an external cyber attack [133299]. This incident aligns more with the intent of the software failure being categorized under "poor_decisions" as it was a deliberate and malicious act by external actors rather than an accidental or unintended decision.
Capability (Incompetence/Accidental) accidental (a) The software failure incident in the Los Angeles Unified School District was not attributed to development incompetence. The incident was described as a ransomware attack, indicating an external cyber attack on the Information Technology assets of the district [133299]. (b) The software failure incident was accidental in the sense that it was not caused by internal incompetence but rather by external malicious actors who targeted the district's IT systems with ransomware. The attack was described as criminal in nature, and the district implemented a response protocol to mitigate disruptions caused by the attack [133299].
Duration temporary (a) The software failure incident in the Los Angeles Unified School District due to the ransomware attack can be considered temporary. The incident caused "significant disruption" but did not lead to the cancellation of classes, indicating that the impact was not permanent [133299]. The district implemented a response protocol to mitigate disruptions, including access to email, computer systems, and applications, suggesting that the issue was being actively addressed to restore normal operations [133299].
Behaviour other (a) crash: The software failure incident in the Los Angeles Unified School District was not described as a crash where the system loses state and does not perform any of its intended functions [133299]. (b) omission: The incident did not mention the system omitting to perform its intended functions at an instance [133299]. (c) timing: The incident did not involve the system performing its intended functions correctly but too late or too early [133299]. (d) value: The software failure incident did not mention the system performing its intended functions incorrectly [133299]. (e) byzantine: The incident did not describe the system behaving erroneously with inconsistent responses and interactions [133299]. (f) other: The behavior of the software failure incident was related to a ransomware attack that caused "significant disruption" to the Information Technology systems of the Los Angeles Unified School District, leading to the implementation of response protocols to mitigate district-wide disruptions [133299].

Consequence property, delay The consequence of the software failure incident in the Los Angeles Unified School District ransomware attack was primarily related to property and delay: (d) property: The ransomware attack caused "significant disruption" but did not lead to the cancellation of classes. The attack targeted the Information Technology systems of the school district, leading to disruptions in business operations, access to email, computer systems, and applications. The attackers encrypted data and potentially demanded ransom payments in return for decryption keys, impacting the district's IT assets [133299]. (e) delay: While schools remained open, the district mentioned that business operations might be delayed or modified as a result of the attack. This indicates that there were delays in the normal functioning of the district's operations due to the ransomware incident [133299].
Domain knowledge (a) The failed system was intended to support the education industry. The Los Angeles Unified School District, one of the largest public school systems in the U.S., was targeted by a ransomware attack, causing significant disruption but not leading to the cancellation of classes [133299]. The attack on the district's Information Technology assets affected business operations, including access to email, computer systems, and applications, highlighting the impact on the educational sector. The incident did not compromise employee healthcare and payroll information or safety and emergency mechanisms in schools. The attack was likely criminal in nature, and the district implemented a response protocol to mitigate disruptions [133299]. Additionally, U.S. government agencies issued a public advisory mentioning that ransomware gangs, such as Vice Society, have been targeting the education sector with ransomware attacks, indicating the specific targeting of educational institutions [133299].
