| Category | Option | Rationale |
|---|---|---|
| Recurring | unknown | The articles do not provide information about the software failure incident happening again at either the same organization (one_organization) or at multiple organizations (multiple_organization). |
| Phase (Design/Operation) | design, operation | (a) The software failure incident in this case appears to be related to the design phase. The incident involved a cyber-attack on Medibank's databases, indicating a failure due to contributing factors introduced by system development or updates. The hackers were able to breach the company's computer systems and steal sensitive customer data, highlighting vulnerabilities in the system's design or security measures [135446]. (b) Additionally, the software failure incident can also be attributed to the operation phase. The incident involved the operation of the system being compromised by the hackers who gained unauthorized access to the data through the exploitation of system vulnerabilities. This indicates a failure due to contributing factors introduced by the operation or misuse of the system [135446]. |
| Boundary (Internal/External) | within_system, outside_system | (a) within_system: The software failure incident of the data breach at Medibank, Australia's largest private health insurer, was caused by a cyber-attack believed to have been coordinated from Russia. The hackers infiltrated Medibank's databases and stole sensitive customer data, including private health information of nearly 10 million Australians [135446]. (b) outside_system: The cyber-attack on Medibank, resulting in the data breach, was orchestrated by a Russian ransomware criminal organization. The attack originated from outside the system, with the hackers demanding a ransom after stealing the data and posting it on the dark web [135446]. |
| Nature (Human/Non-human) | non-human_actions, human_actions | (a) The software failure incident in this case occurred due to non-human actions, specifically a cyber-attack believed to have been coordinated from Russia. The hackers, identified as a Russian ransomware criminal organization, hacked into the databases of Medibank, Australia's largest private health insurer, stealing sensitive customer data [135446]. (b) Human actions also played a role in this software failure incident. The hackers demanded a ransom of US$9.7 million from Medibank, and when the company refused to pay, the hackers began releasing the stolen data online. Additionally, the Australian Federal Police and cybersecurity officials are actively involved in investigating and responding to the incident, indicating human actions in the response to the cyber-attack [135446]. |
| Dimension (Hardware/Software) | software | (a) The software failure incident in this case does not seem to be related to hardware issues. The incident is primarily attributed to a cyber-attack orchestrated by a Russian ransomware criminal organization targeting the databases of Medibank, Australia's largest private health insurer [135446]. (b) The software failure incident is directly linked to software issues, specifically a cyber-attack involving ransomware that compromised the data of nearly 10 million Australians. The hackers infiltrated Medibank's computer systems, stole sensitive customer data, and demanded a ransom. The incident involved the unauthorized access and theft of data, indicating a software-related failure [135446]. |
| Objective (Malicious/Non-malicious) | malicious | (a) The software failure incident in this case is malicious. The failure occurred due to a cyber-attack believed to have been coordinated from Russia by a Russian ransomware criminal organization. The hackers hacked into the databases of Medibank, Australia’s largest private health insurer, and stole sensitive customer data, including private health information such as treatments for alcoholism, drug addictions, and pregnancy terminations. The hackers demanded a ransom from Medibank, and when the ransom was not paid, they began releasing the stolen data on the dark web [135446]. The Australian Federal Police commissioner stated that they know the identity of the Russian hackers responsible for the breach and that the attack was likely not limited to Russian soil, with some affiliates of the organization possibly operating in other countries [135446]. |
| Intent (Poor/Accidental Decisions) | unknown | The articles do not provide information about the intent of the software failure incident in terms of poor decisions or accidental decisions. Therefore, it is unknown whether the failure was due to poor decisions or accidental decisions. |
| Capability (Incompetence/Accidental) | accidental | (a) The software failure incident in the article is not attributed to development incompetence. The incident is primarily described as a cyber-attack orchestrated by a Russian ransomware criminal organization targeting the databases of Medibank, Australia's largest private health insurer [135446]. (b) The software failure incident in the article is attributed to accidental factors. The incident involved a cyber-attack where hackers gained unauthorized access to Medibank's computer systems, stealing sensitive customer data including private health information. This breach was not intentional or caused by incompetence but rather a deliberate criminal act [135446]. |
| Duration | unknown | The software failure incident reported in the articles is not related to a temporary or permanent failure but rather a cyber-attack involving hacking and data breach. Therefore, the duration of the incident does not fall under the categories of temporary or permanent software failure. |
| Behaviour | crash, omission, value, other | (a) crash: The software failure incident in this case can be categorized as a crash. The incident involved a cyber-attack on Medibank's databases, resulting in the system losing control and sensitive customer data being compromised. The system failed to perform its intended function of safeguarding customer information, leading to a significant breach [135446]. (b) omission: The incident can also be classified as an omission. The hackers omitted to respect the privacy and security of the 9.7 million current and former Medibank customers by stealing their personal information, including names, dates of birth, phone numbers, email addresses, and addresses. This omission led to the exposure of sensitive data [135446]. (c) timing: There is no specific mention of a timing-related failure in this incident. (d) value: The software failure incident can be linked to a value failure. The system failed to uphold the value of data security and privacy for the affected customers. The hackers accessed and released sensitive medical records, including details of treatments for alcoholism, drug addictions, and pregnancy terminations, compromising the integrity of the data [135446]. (e) byzantine: The incident does not align with a byzantine failure scenario. (f) other: The other behavior exhibited in this software failure incident is a deliberate and malicious attack by a cybercriminal organization. The hackers demanded a ransom from Medibank, and when the ransom was not paid, they proceeded to release sensitive customer data on the dark web. This behavior goes beyond typical system failures and involves intentional criminal actions [135446]. |
