Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident having happened again at one_organization: - Google had previously experienced a vulnerability in July 2010 that allowed hackers to attach off-color pop-ups and adult-site redirects to YouTube videos [8687]. (b) The software failure incident having happened again at multiple_organization: - There is no specific mention in the provided article about similar incidents happening at other organizations.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the hacking incident on Sesame Street's YouTube channel. The hackers were able to exploit a vulnerability in YouTube that allowed them to replace the family-friendly content with pornographic material. This vulnerability was previously identified and patched by Google in July 2010, but it seems that the fix was not comprehensive enough to prevent similar attacks in the future [8687]. (b) The software failure incident related to the operation phase is evident in the unauthorized access and misuse of the Sesame Street YouTube channel by hackers. The incident occurred due to the operation of the system, where hackers were able to gain access and alter the channel's content and profile page, causing significant disruption. This highlights the importance of robust security measures and monitoring to prevent unauthorized access and misuse of systems [8687].
Boundary (Internal/External) within_system, outside_system (a) The software failure incident involving Sesame Street's YouTube channel being hacked can be categorized as within_system. The incident was caused by hackers who were able to alter the channel's content and profile page, indicating that the contributing factors originated from within the system itself [8687]. Additionally, the vulnerability that was exploited by the hackers had been previously identified and patched by Google in July 2010, further highlighting an internal system weakness that was exploited by external actors [8687].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in this case was primarily due to non-human actions, specifically a hack on Sesame Street's YouTube channel. The hackers were able to replace the family-friendly content with pornographic material, indicating that the failure was caused by external malicious actors rather than internal human error [8687]. (b) However, human actions were also involved in the incident as YouTube representatives had to take action to remove the inappropriate content and restore the channel. Additionally, there were reports of a YouTube user called MrEdxwx being implicated in the hacking, although this user denied responsibility in a subsequent video [8687].
Dimension (Hardware/Software) software (a) The software failure incident reported in Article 8687 was not attributed to hardware issues but rather to a hack. The incident involved the hacking of Sesame Street's YouTube channel, where hackers replaced the family-friendly content with pornographic material. This hack was not related to any hardware failure but rather a security breach on the software platform. The vulnerability exploited by the hackers was a software-related issue, specifically a cross-site scripting vulnerability that allowed them to insert unauthorized content onto the YouTube channel [8687].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident related to the hacking of Sesame Street's YouTube channel was malicious in nature. The hackers replaced the family-friendly content with pornographic material, altered the channel's profile page with inappropriate messages, and even expressed intentions to keep control of the account to continue posting such content. This indicates that the incident was driven by malicious intent to harm the system and disrupt the normal operations of the channel [8687].
Intent (Poor/Accidental Decisions) poor_decisions (a) The intent of the software failure incident related to poor_decisions: - The hacking incident on Sesame Street's YouTube channel, where pornographic content was uploaded, was likely a result of poor decisions made by the hackers who gained unauthorized access to the channel [8687]. - The hackers altered the channel's profile page and left a message indicating their intent to disrupt the family-friendly content with inappropriate material, showcasing a deliberate act of poor decision-making [8687]. (b) The intent of the software failure incident related to accidental_decisions: - There is no indication in the articles that the software failure incident was a result of accidental decisions. The incident, involving the hacking of Sesame Street's YouTube channel, appears to be a deliberate act by the hackers to replace the content with inappropriate material [8687].
Capability (Incompetence/Accidental) development_incompetence, unknown (a) The software failure incident related to development incompetence is evident in the hacking of Sesame Street's YouTube channel. The hackers were able to replace the family-friendly content with pornographic material, indicating a breach in security measures that should have prevented such unauthorized access and content modification. Additionally, the incident highlights a vulnerability that was previously exploited in 2010, suggesting a lack of robust security measures implemented by YouTube to prevent similar attacks [8687]. (b) The accidental aspect of the software failure incident is not explicitly mentioned in the provided article.
Duration temporary (a) The software failure incident in this case was temporary. The Sesame Street YouTube channel was hacked, leading to the replacement of family-friendly content with pornographic material. However, YouTube was able to remove the inappropriate content within 22 minutes of the incident being reported, indicating that the failure was not permanent [8687].
Behaviour crash, other (a) crash: The software failure incident in Article 8687 can be categorized as a crash. The Sesame Street YouTube channel was hacked, leading to its content being replaced with pornographic material, causing the system to lose its intended state of providing family-friendly content [8687]. (b) omission: There is no specific mention of the software failure incident in Article 8687 being related to the system omitting to perform its intended functions at an instance(s). (c) timing: The incident in Article 8687 does not relate to the system performing its intended functions correctly but too late or too early. (d) value: The software failure incident in Article 8687 does not involve the system performing its intended functions incorrectly. (e) byzantine: The behavior of the software failure incident in Article 8687 does not align with the system behaving erroneously with inconsistent responses and interactions. (f) other: The other behavior exhibited in the software failure incident in Article 8687 is the unauthorized access and manipulation of the Sesame Street YouTube channel by hackers, resulting in the display of inappropriate content and a message on the channel's profile page [8687].
