Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident related to TeamViewer being hacked has happened again within the same organization. Users reported their accounts being hacked, despite TeamViewer blaming poor password choices and users with the same credentials across different platforms. Even users with two-factor authentication enabled reported being hacked [45069].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the TeamViewer account breaches reported in the news article. Users reported that their accounts were hacked, leading to unauthorized access, purchases, and malware installations. TeamViewer spokesman Axel Schmidt attributed these breaches to poor password choices and users using the same credentials across different platforms, indicating a design flaw in the system's security measures [Article 45069]. (b) The software failure incident related to the operation phase is evident in users reporting being hacked despite having two-factor authentication enabled. This indicates a failure in the operational aspect of the system's security measures, where even additional security layers were not effective in preventing unauthorized access [Article 45069].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident involving TeamViewer accounts being hacked can be attributed to poor password choices and users with accounts using the same credentials across different platforms, as stated by TeamViewer spokesman Axel Schmidt [45069]. Additionally, despite having two-factor authentication enabled, many users still reported being hacked, indicating a failure within the system's security measures. (b) outside_system: The software failure incident also involved external factors such as hackers gaining unauthorized access to user accounts, installing malicious malware, and making purchases using user information [45069]. These external factors contributed to the breach of TeamViewer accounts, indicating a failure originating from outside the system.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident occurring due to non-human actions: The software failure incident reported in Article 45069 regarding TeamViewer accounts being hacked was attributed to poor password choices by users and the reuse of credentials across different platforms. The article mentions that despite some users having two-factor authentication enabled, they still reported being hacked, indicating that the breach was not solely due to human actions but also due to vulnerabilities in the system that allowed for unauthorized access [45069]. (b) The software failure incident occurring due to human actions: The same software failure incident reported in Article 45069 also highlights human actions as contributing factors to the account breaches. The TeamViewer spokesman mentioned that poor password choices and users using the same credentials across different platforms were to blame for the significant amount of account breaches. Additionally, the article provides steps for users to take, such as changing passwords and enabling two-factor authentication, which are actions that users can take to prevent further breaches caused by human errors [45069].
