He found vulnerabilities in the firmware of these devices, which could allow unauthorized users to reprogram the gates or spoof data, potentially enabling smuggling of radioactive material past security checks [61274].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the vulnerabilities found by security researcher Ruben Santamarta in the software and hardware systems designed to protect against radioactive contamination at nuclear facilities. Santamarta identified serious weaknesses in the equipment that helps protect against radioactive leaks or terrorist attacks, highlighting flaws in the design of the radioactivity sensor systems and gate-monitoring systems [61274]. (b) The software failure incident related to the operation phase is evident in the potential consequences of the vulnerabilities discovered by Santamarta. If exploited by hackers or malicious insiders, these flaws could lead to disabling monitoring tools, allowing dangerous nuclear materials to bypass checkpoints, and potentially causing confusion among nuclear engineers or preventing them from responding to ongoing radioactive leaks [61274].
Boundary (Internal/External) within_system (a) within_system: The software failure incident described in the articles is primarily within the system. The vulnerabilities and flaws identified by security researcher Ruben Santamarta in the software and hardware systems designed to protect against radioactive contamination were found within the systems themselves. For example, Santamarta found serious vulnerabilities in radioactivity sensors and gate-monitoring systems used in nuclear facilities, which could be exploited by hackers to send false data, block real signals, disable monitoring tools, and potentially allow dangerous nuclear materials to bypass security checkpoints [61274]. These vulnerabilities were inherent to the design and implementation of the software and hardware systems, making them within-system failures.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident occurring due to non-human actions: The software failure incident described in the articles is primarily due to vulnerabilities in the software and hardware systems designed to protect against radioactive contamination at nuclear facilities. Security researcher Ruben Santamarta identified serious weaknesses in the equipment that helps protect against radioactive leaks or terrorist attacks. These vulnerabilities could potentially confuse nuclear engineers or prevent them from responding to an ongoing radioactive leak. For example, Santamarta found that the radioactivity sensor firm Mirion's sensors lacked encryption and authentication, allowing for the injection of false data into the plant's monitoring systems [61274]. (b) The software failure incident occurring due to human actions: The software failure incident also involves human actions contributing to the failure. Santamarta demonstrated how a hacker could exploit vulnerabilities in the software and hardware systems to send spoofed data to a nuclear plant's monitoring systems, potentially blocking real signals and increasing the time an attack involving radioactive material remains undetected. Additionally, he found that the vehicle gates designed to detect radiation communicated with the server collecting data without encryption or authentication, allowing attackers to spoof data or act as a man-in-the-middle [61274].

(b) The software failure incident occurring due to software: - The incident involved vulnerabilities in the software systems used for radioactivity detection and monitoring at nuclear facilities [61274]. - Santamarta discovered that the software communications between radioactivity sensors and transceivers had no encryption or authentication, allowing for the transmission of false data [61274]. - The gate-monitoring systems analyzed by Santamarta had firmware vulnerabilities that could allow unauthorized users to reprogram the devices with hardcoded passwords, potentially compromising the integrity of the software [61274].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident described in the articles is malicious in nature. The incident involves a security researcher, Ruben Santamarta, who identified serious vulnerabilities in software and hardware systems designed to protect against radioactive contamination at nuclear facilities. Santamarta demonstrated how these vulnerabilities could be exploited by hackers to send false data to radioactivity sensors, potentially confusing nuclear engineers or preventing them from responding to a radioactive leak. Additionally, he highlighted weaknesses in gate-monitoring systems that could be hacked to allow dangerous nuclear materials to bypass security checkpoints, enabling smuggling of radioactive materials [61274]. These actions were carried out with the intent to harm the systems and potentially cause serious consequences. (b) The software failure incident is non-malicious in the sense that the vulnerabilities were not intentionally introduced by the system developers or operators to harm the system. Rather, the vulnerabilities were discovered by a security researcher, Ruben Santamarta, who conducted tests on equipment from radioactivity sensor firms and identified weaknesses in their security measures. The vulnerabilities were not created with malicious intent but could be exploited by malicious actors to cause harm [61274].
Intent (Poor/Accidental Decisions) poor_decisions (a) The intent of the software failure incident related to poor_decisions: - The software failure incident in the articles is related to poor decisions made by the companies involved in designing and implementing the radioactivity detection equipment. The vulnerabilities in the software and hardware systems designed to protect against radioactive contamination were due to lack of encryption, authentication, and security measures in the products [Article 61274]. - The companies involved, such as Mirion and Ludlum, did not prioritize security when designing their products, leading to serious weaknesses in the equipment that helps protect against radioactive leaks or terrorist attacks [Article 61274]. - The lack of encryption and authentication in the systems allowed for potential attacks by hackers to send false data, block real signals, and potentially confuse nuclear engineers or prevent them from responding to ongoing radioactive leaks [Article 61274]. - The companies dismissed the security concerns raised by the researcher, Ruben Santamarta, indicating a lack of proactive measures to address the vulnerabilities in their products [Article 61274].
Capability (Incompetence/Accidental) development_incompetence (a) The software failure incident related to development incompetence is evident in the article where security researcher Ruben Santamarta identified serious vulnerabilities in the software and hardware systems designed to protect against radioactive contamination at nuclear facilities [61274]. Santamarta found that the radioactivity sensor firm Mirion's sensors lacked encryption and authentication, allowing for potential attacks to send false data to the monitoring systems. Additionally, he discovered flaws in products sold by the radioactive-monitoring-equipment firm Ludlum, such as hardcoded passwords and lack of encryption in communication with servers, which could lead to unauthorized access and data spoofing [61274]. (b) The software failure incident related to accidental factors is demonstrated in the article where Santamarta highlighted the lack of security considerations in the design of products by Mirion, Ludlum, and Digi, which are crucial for nuclear power plants, borders, and secure facilities. The vulnerabilities identified by Santamarta, such as the absence of encryption and authentication in the systems, were not intentional but rather oversights in the development process that could potentially be exploited by malicious actors [61274].
Duration permanent (a) The software failure incident described in the articles is more likely to be permanent rather than temporary. The vulnerabilities and weaknesses identified in the software and hardware systems designed to protect against radioactive contamination at nuclear facilities could have long-lasting implications if not addressed. For example, the ability to send false data to the radioactivity sensors and gate-monitoring systems could potentially lead to confusion among nuclear engineers or prevent them from responding to ongoing radioactive leaks ([61274]). Additionally, the lack of encryption and authentication in the communication systems of these devices could allow for spoofing and smuggling of radioactive materials, posing a significant and enduring risk to security ([61274]).
Behaviour value, other (a) crash: The software failure incident described in the articles does not involve a crash where the system loses state and does not perform any of its intended functions. Instead, the vulnerabilities identified by the security researcher could potentially lead to false data being injected into the monitoring systems, potentially blocking real signals as well [61274]. (b) omission: The incident does not involve the system omitting to perform its intended functions at an instance(s). However, the vulnerabilities identified could allow for the omission of detecting real radioactive leaks or terrorist attacks, as hackers could send false readings or prevent real signals from reaching operators [61274]. (c) timing: The failure is not related to the system performing its intended functions too late or too early. However, the vulnerabilities identified could potentially increase the time an attack involving radioactive material remains undetected by sending normal readings to trick operators into thinking measurements are fine [61274]. (d) value: The software failure incident does involve the system performing its intended functions incorrectly. The vulnerabilities identified could lead to the system receiving false data, potentially confusing nuclear engineers or preventing them from responding to an ongoing radioactive leak [61274]. (e) byzantine: The incident does not involve the system behaving erroneously with inconsistent responses and interactions. However, the vulnerabilities identified could allow for malicious actors to hack monitoring tools, disable them, and potentially smuggle dangerous nuclear materials past security checkpoints [61274]. (f) other: The software failure incident involves the system potentially being manipulated by hackers to send arbitrary or malicious information that emulates a radiation leak that is not actually happening, or to send regular readings to make an accident go undetected. This behavior is not explicitly covered by the options provided [61274].
