Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident having happened again at one_organization: The article mentions that the breach of the Republican Governors Association (RGA) was a result of exploiting critical vulnerabilities in Microsoft Exchange Server, a popular email software program. This incident occurred after the discovery of vulnerabilities in the same software that exposed organizations across the US and Europe to hacking [118824]. (b) The software failure incident having happened again at multiple_organization: The article highlights that the breach of the RGA was part of a larger hacking campaign that targeted vulnerable organizations with ransomware and other scams after the Microsoft Exchange Server vulnerabilities were exploited. This indicates that multiple organizations were affected by similar incidents following the initial discovery of the software flaws [118824].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be attributed to the critical vulnerabilities in Microsoft Exchange Server, a popular email software program, that exposed organizations across the US and Europe to hacking [118824]. The breach exploited Microsoft software, indicating a design flaw or vulnerability in the system that allowed hackers to gain unauthorized access to the Republican Governors Association's network. (b) The software failure incident related to the operation phase is evident in the delayed awareness of the intruders in the RGA network. The RGA only became aware of the attackers in its network on March 10, eight days after the public statement about the hacking campaign related to Microsoft Exchange Server vulnerabilities [118824]. This delay in detection and response can be considered an operational failure as it allowed the hackers to access and potentially compromise the organization's data.
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident involving the breach of the Republican Governors Association (RGA) was primarily due to critical vulnerabilities in Microsoft Exchange Server, a popular email software program. The breach exploited these software flaws, allowing attackers to access a small portion of the RGA's email environment [118824]. (b) outside_system: The breach of the RGA was also influenced by external factors, such as the actions of hackers who exploited the Microsoft software vulnerabilities. Additionally, the incident was part of a broader trend where cybercriminal groups took advantage of the situation created by the initial Microsoft breaches to target vulnerable organizations with ransomware and other scams [118824].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident occurring due to non-human actions: The software failure incident involving the breach of the Republican Governors Association was attributed to hackers exploiting critical vulnerabilities in Microsoft Exchange Server, a popular email software program. The breach was part of a larger hacking campaign that targeted organizations across the US and Europe. Initially, Chinese government-linked operatives were identified as exploiting the software flaws, but cybercriminal groups also took advantage of the situation to target vulnerable organizations with ransomware and other scams [118824]. (b) The software failure incident occurring due to human actions: The response to the software failure incident involved the RGA updating its Microsoft software after the breach was discovered. Additionally, the FBI used a court order to remove malicious code from hundreds of US computers using Exchange Server to mitigate the impact of the hacks. The incident highlighted the importance of organizations applying software updates promptly to protect themselves from compromise [118824].
Dimension (Hardware/Software) hardware, software (a) The software failure incident related to hardware: - The breach of the Republican Governors Association (RGA) was attributed to hackers exploiting critical vulnerabilities in Microsoft Exchange Server, a popular email software program [118824]. - The breach occurred due to the exploitation of software flaws in Microsoft Exchange Server, which allowed attackers to access the RGA network [118824]. (b) The software failure incident related to software: - The breach of the RGA was a result of hackers exploiting vulnerabilities in Microsoft software [118824]. - The RGA updated its Microsoft software after the breach to enhance its security [118824].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident reported in the article is malicious in nature. Hackers breached the Republican Governors Association's network by exploiting critical vulnerabilities in Microsoft Exchange Server, potentially exposing personal data of nearly 500 people affiliated with the organization, including Social Security numbers [118824]. The breach was attributed to Chinese government-linked operatives with a history of targeting defense contractors and infectious disease researchers. Additionally, cybercriminal groups took advantage of the situation to target vulnerable organizations with ransomware and other scams after the software flaws were exploited [118824]. (b) unknown
Intent (Poor/Accidental Decisions) poor_decisions (a) The intent of the software failure incident related to poor_decisions: - The software failure incident involving the breach of the Republican Governors Association was a result of poor decisions related to cybersecurity practices and software management. - The incident was linked to critical vulnerabilities in Microsoft Exchange Server, a popular email software program, that were exploited by hackers. These vulnerabilities exposed organizations to hacking, including the RGA. - The RGA only became aware of the intruders in its network on March 10, eight days after Microsoft's public statement about the hacking campaign, indicating a delay in response and detection. - The RGA mentioned that it updated its Microsoft software after the breach, suggesting that the software may not have been promptly updated to address known vulnerabilities. - The incident highlights the importance of timely software updates and robust cybersecurity measures to prevent such breaches in the future [118824].
Capability (Incompetence/Accidental) development_incompetence (a) The software failure incident related to development incompetence is evident in the breach of the Republican Governors Association (RGA) network, which exploited critical vulnerabilities in Microsoft Exchange Server software. The RGA became aware of the intruders in its network eight days after Microsoft's public statement about the hacking campaign, indicating a lack of proactive monitoring and response mechanisms [118824]. (b) The software failure incident related to accidental factors is seen in the initial Microsoft breaches, where Chinese government-linked operatives exploited software flaws. This incident led to cybercriminal groups taking advantage of the situation to target vulnerable organizations with ransomware and other scams, showcasing the unintended consequences of the initial breach [118824].
Duration temporary (a) The software failure incident in this case was temporary. The breach of the Republican Governors Association network occurred on February 28, but it wasn't until March 10 that the RGA became aware of the intruders in its network [118824]. This indicates that the breach was not a permanent failure but rather a temporary one that was eventually discovered and addressed.
Behaviour other (a) crash: The incident involving the Republican Governors Association (RGA) was not described as a crash where the system loses state and does not perform any of its intended functions [118824]. (b) omission: The software failure incident did not involve the system omitting to perform its intended functions at an instance(s) [118824]. (c) timing: The incident did not involve the system performing its intended functions correctly, but too late or too early [118824]. (d) value: The software failure incident did not involve the system performing its intended functions incorrectly [118824]. (e) byzantine: The incident did not involve the system behaving erroneously with inconsistent responses and interactions [118824]. (f) other: The behavior of the software failure incident was related to a security breach where hackers exploited vulnerabilities in Microsoft software to access the RGA's network and potentially expose personal data, including Social Security numbers, of individuals affiliated with the organization [118824].
