(a) The software failure incident occurring due to non-human actions:
The software failure incident in this case was due to a security vulnerability in the My Satis Android app that communicates with the high-tech Satis toilet using Bluetooth. The app had a hard-coded Bluetooth PIN of 0000, allowing any person using the application to control the toilet. This vulnerability could be exploited by malicious attackers to take control of various functions of the toilet remotely, such as repeatedly flushing, opening and closing the lid unexpectedly, activating the air-dry function, and triggering the water-jet bidet feature without warning [21249].
(b) The software failure incident occurring due to human actions:
The failure in this case was not directly caused by human actions but rather by a security vulnerability introduced in the software design. However, it is worth noting that the vulnerability was likely introduced during the development and implementation of the My Satis Android app by the developers who hard-coded the Bluetooth PIN as 0000. Additionally, the lack of response from the manufacturer to address the vulnerability despite being contacted by Trustwave multiple times could be considered a human action contributing to the incident [21249]. |
| Dimension (Hardware/Software) |
hardware, software |
(a) The software failure incident in the article is related to hardware as it involves a high-tech smart toilet, the Satis toilet from LIXIL, being hacked through its accompanying My Satis Android app which communicates with the toilet using Bluetooth [21249].
(b) The software failure incident is also related to software as the vulnerability lies in the hard-coded Bluetooth PIN (0000) in the My Satis Android app, allowing any person using the application to control the Satis toilet, leading to potential malicious actions like repeatedly flushing the toilet, opening and closing the lid unexpectedly, activating the air-dry function, and triggering the water-jet bidet feature without warning [21249]. |
| Objective (Malicious/Non-malicious) |
malicious |
(a) The software failure incident in this case is malicious. The incident involved a security vulnerability in the My Satis Android app that communicates with the high-tech Satis toilet using Bluetooth. The app had a hard-coded Bluetooth PIN of 0000, allowing any person using the application to control the toilet. Malicious attackers could exploit this vulnerability to take control of the toilet, causing actions such as repeatedly flushing, opening and closing the lid unexpectedly, activating the air-dry function, and triggering the water-jet bidet feature at inconvenient times, potentially causing discomfort or distress to the user [21249]. This indicates that the software failure was a result of contributing factors introduced by humans with the intent to harm the system.
(b) There is no information in the article suggesting that the software failure incident was non-malicious. |
| Intent (Poor/Accidental Decisions) |
poor_decisions |
(a) The intent of the software failure incident related to poor_decisions:
- The software failure incident involving the high-tech Satis toilet from LIXIL was due to poor decisions in terms of security implementation.
- The My Satis Android application had a hard-coded Bluetooth PIN of 0000, making it easy for any person using the application to control any Satis toilet, leading to the vulnerability exploited by malicious attackers [21249]. |
| Capability (Incompetence/Accidental) |
development_incompetence, accidental |
(a) The software failure incident in the article can be attributed to development incompetence. The high-tech Satis toilet from LIXIL was found to have a security vulnerability that allowed malicious attackers to take control of the toilet through the My Satis Android app. The vulnerability stemmed from a hard-coded Bluetooth PIN of 0000 in the application, allowing anyone using the app to control any Satis toilet. Despite Trustwave contacting the manufacturer about the vulnerability multiple times, there was no response, indicating a lack of professional competence in addressing and fixing the security issue [21249].
(b) The software failure incident can also be considered accidental. The presence of a hard-coded Bluetooth PIN of 0000 in the My Satis Android app was likely unintentional, leading to the vulnerability that allowed malicious attackers to control the high-tech toilet. Additionally, the unexpected activation of functions such as the air-dry feature and the water-jet bidet could be seen as accidental consequences of the security vulnerability, causing discomfort or distress to users [21249]. |
| Duration |
temporary |
The software failure incident reported in Article 21249 describes a temporary failure. The vulnerability in the high-tech Satis toilet from LIXIL was due to a specific contributing factor - the hard-coded Bluetooth PIN of 0000 in the My Satis Android app. This specific factor allowed any person using the application to control the toilet, leading to potential malicious actions like repeatedly flushing, opening and closing the lid unexpectedly, activating the air-dry function, and triggering the water-jet bidet feature. The failure was not permanent as it was caused by a specific flaw in the software's design, rather than being inherent to all circumstances [21249]. |
| Behaviour |
crash, omission, value, other |
(a) crash: The software failure incident in the article can be categorized as a crash since the high-tech Satis toilet's software vulnerability could potentially lead to the system losing control and performing unintended actions such as repeatedly flushing, opening and closing the lid unexpectedly, activating functions without warning, and causing discomfort to the user [21249].
(b) omission: The software failure incident can also be classified as an omission since the vulnerability in the My Satis Android app allowed attackers to control the toilet and potentially omit its intended functions by activating features like the air-dry function, the posterior nozzle water-jet bidet, and other functions without the user's consent or expectation [21249].
(c) timing: While the incident does not directly relate to timing failures, the potential consequences of the software vulnerability could lead to the system performing its functions at inappropriate times, such as activating the bidet feature unexpectedly, causing discomfort or distress to the user [21249].
(d) value: The software failure incident can be associated with a value failure as the vulnerability allowed attackers to control the Satis toilet and potentially perform its functions incorrectly, such as repeatedly flushing, opening and closing the lid, and activating features without the user's consent, leading to increased water usage, utility costs, and user discomfort [21249].
(e) byzantine: The software failure incident does not align with a byzantine failure, which involves inconsistent responses and interactions within a distributed system. The incident described in the article primarily focuses on a security vulnerability in the Satis toilet's software that could be exploited by malicious attackers to control the device and trigger various functions [21249].
(f) other: The software failure incident can be further categorized as an "other" behavior since it involves the system behaving in unexpected ways due to a security vulnerability. The incident showcases how a high-tech smart toilet's software flaw could lead to unusual and potentially disruptive actions, such as unexpected flushing, lid movements, and bidet activations controlled by external attackers [21249]. |
