They are programmed with a control logic that defines how to drive and operate critical processes such as nuclear power plants, petrochemical factories, water treatment systems, and other facilities. Unfortunately, these devices are not fully secure and are prone to malicious threats, especially those exploiting vulnerabilities in the control logic of PLCs. Such threats are known as control logic injection attacks. They mainly aim at sabotaging physical processes controlled by exposed PLCs, causing catastrophic damage to target systems as shown by Stuxnet. Looking back over the last decade, many research endeavors exploring and discussing these threats have been published. In this article, we present a flashback on the recent works related to control logic injection attacks against PLCs.

Most representatives of the plants have evolved to be highly energy-efficient in their survival strategies, despite their limited resources. Plants have to deal with a variety of threats originating from different herbivores and microbial pathogens while handling a number of abiotic stress factors. For plants and WSNs, different defence mechanisms impose different fitness costs and therefore the costs and benefits have to be well-balanced. This way, plants are able to not only conquer a large variety of different attacks but also handle several different simultaneous attacks adequately. To react early and adapt to upcoming threats, plants within a network are capable of signalling each other within a certain distance about ongoing attacks. The biological strategies of plants in terms of signalling and defence, as well as their energy and resource limitations, share significant similarities with WSNs. This study aims to explore these similarities and demonstrates the correspondence between the biological concepts and WSNs. Additionally, we present a novel approach to enhancing security in WSNs through a cooperative distributed security scheme inspired by key factors of plant defence mechanisms, with the goal of reducing the energy constraints and maximising the longevity of the network.}, language = {en} } @misc{AlsabbaghLangendoerfer, author = {Alsabbagh, Wael and Langend{\"o}rfer, Peter}, title = {You Are What You Attack: Breaking the Cryptographically-Protected S7 Protocol}, series = {19th International Conference on Factory Communication Systems (WFCS), (2023)}, journal = {19th International Conference on Factory Communication Systems (WFCS), (2023)}, publisher = {IEEE}, isbn = {978-1-6654-6432-1}, issn = {2835-8414}, doi = {10.1109/WFCS57264.2023.10144251}, pages = {8}, abstract = {S7 protocol defines an appropriate format for exchanging messages between SIMATIC S7 PLCs and their corresponding engineering software i.e., TIA Portal.

This paper addresses exactly this point, and investigates the security of the most developed integrity check mechanism that the newest S7CommPlus protocol version implements. Our results showed that the latest S7 PLC models as well as their related protocols are still vulnerable. We found that adversaries can manipulate two hashes that play a significant role in generating keys and bytes for the encryption processes implemented in the S7CommPlus protocol. This allows to reproduce S7 packets and conduct several attacks that eventually impact the operation of the target PLC and the entire physical process it controls.

Octopus-inspired robotic arms belong to continuum robots which are used in minimally invasive surgery or for technical system restoration in areas difficult-to-access. Continuum robot missions are bounded with their motions, whereby the motion of the robots is controlled by humans via wireless communication. In case of a lost connection, robot autonomy is required. Distributed control and distributed decision-making mechanisms based on artificial intelligence approaches can be a promising solution to achieve autonomy of technical systems and to increase their resilience. However these methods are not well investigated yet. Octopuses are the living example of natural distributed intelligence but their learning and decision-making mechanisms are also not fully investigated and understood yet. Our major interest is investigating mechanisms of Distributed Artificial Intelligence as a basis for improving resilience of complex systems. We decided to use a physical continuum robot prototype that is able to perform some basic movements for our research. The idea is to research how a technical system can be empowered to combine movements into sequences of motions by itself. For the experimental investigations a suitable physical prototype has to be selected, its motion control has to be implemented and automated. In this paper, we give an overview combining different fields of research, such as Distributed Artificial Intelligence and continuum robots based on 98 publications. We provide a detailed description of the basic motion control models of continuum robots based on the literature reviewed, discuss different aspects of autonomy and give an overview of physical prototypes of continuum robots.}, language = {en} } @misc{FoersterLangendoerferHinze, author = {F{\"o}rster, Benjamin and Langend{\"o}rfer, Peter and Hinze, Thomas}, title = {Determining Distributions of Security Means for Wireless Sensor Networks based on the Model of a Neighbourhood Watch}, series = {arXiv}, journal = {arXiv}, doi = {10.48550/arXiv.2212.09050}, pages = {24}, abstract = {Neighbourhood watch is a concept that allows a community to distribute a complex security task in between all members. Members of the community carry out individual security tasks to contribute to the overall security of it. It reduces the workload of a particular individual while securing all members and allowing them to carry out a multitude of security tasks. Wireless sensor networks (WSNs) are composed of resource-constraint independent battery driven computers as nodes communicating wirelessly. Security in WSNs is essential. Without sufficient security, an attacker is able to eavesdrop the communication, tamper monitoring results or deny critical nodes providing their service in a way to cut off larger network parts. The resource-constraint nature of sensor nodes prevents them from running full-fledged security protocols. Instead, it is necessary to assess the most significant security threats and implement specialised protocols. A neighbourhood-watch inspired distributed security scheme for WSNs has been introduced by Langend\"orfer. Its goal is to increase the variety of attacks a WSN can fend off. A framework of such complexity has to be designed in multiple steps. Here, we introduce an approach to determine distributions of security means on large-scale static homogeneous WSNs. Therefore, we model WSNs as undirected graphs in which two nodes connected iff they are in transmission range. The framework aims to partition the graph into \$n\$ distinct security means resulting in the targeted distribution. The underlying problems turn out to be NP hard and we attempt to solve them using linear programs (LPs). To evaluate the computability of the LPs, we generate large numbers of random {\lambda}-precision unit disk graphs (UDGs) as representation of WSNs. For this purpose, we introduce a novel {\lambda}-precision UDG generator to model WSNs with a minimal distance in between nodes.}, language = {en} } @misc{AlsabbaghAmogbonjayeUrregoetal., author = {Alsabbagh, Wael and Amogbonjaye, Samuel and Urrego, Diego and Langend{\"o}rfer, Peter}, title = {A Stealthy False Command Injection Attack on Modbus based SCADA Systems}, series = {20th Consumer Communications \& Networking Conference (CCNC), (2023)}, journal = {20th Consumer Communications \& Networking Conference (CCNC), (2023)}, isbn = {978-1-6654-9734-3}, issn = {2331-9860}, doi = {10.1109/CCNC51644.2023.10059804}, pages = {9}, abstract = {Modbus is a widely-used industrial protocol in Supervisory Control and Data Acquisition (SCADA) systems for different purposes such as controlling remote devices, monitoring physical processes, data acquisition, etc. Unfortunately, such a protocol lacks security means i.e., authentication, integrity, and confidentiality. This has exposed industrial plants using the Modbus protocol and made them attractive to malicious adversaries who could perform various kinds of cyber-attacks causing significant consequences as Stuxnet showed. In this paper, we exploit the insecurity of the Modbus protocol and perform a stealthy false command injection scenario concealing our injection from the SCADA operator. Our attack approach is comprised of two main phases: 1) Pre-attack phase (offline) where an attacker sniffs, collects and stores sufficient valid request-response pairs in a database, 2) Attack phase (online) where the attacker performs false command injection and conceals his injection by replaying a valid response from his database upon each request sent from the HMI user. Such a scenario is quite severe and might cause disastrous damages in SCADA systems and critical infrastructures if it is successfully implemented by malicious adversaries.

One of the assumptions, on which the atomicity principle is based, is the indistinguishability of operations with different registers, i.e. storing of the data into two different registers cannot be distinguished if their old and new data values are the same. But before the data can be stored in a register/block, this register/block has to be addressed for storing the data. Different registers/blocks have different addresses. The key-dependent addressing of registers/blocks is an inherent feature of the binary kP algorithms and allows to reveal the key k. In our work we demonstrated it. This means that the main assumption, that addressing of different registers/blocks is an indistinguishable operation, may no longer be applied when realizing kP implementations, at least not for hardware implementations.}, language = {en} } @misc{AlsabbaghLangendoerfer, author = {Alsabbagh, Wael and Langend{\"o}rfer, Peter}, title = {Security of Programmable Logic Controllers and Related Systems: Today and Tomorrow}, series = {IEEE Open Journal of the Industrial Electronics Society}, journal = {IEEE Open Journal of the Industrial Electronics Society}, number = {4}, issn = {2644-1284}, doi = {10.1109/OJIES.2023.3335976}, pages = {659 -- 693}, abstract = {Programmable logic controllers (PLCs) are indispensable in critical infrastructures and industrial control systems. The increasing demand for enhanced cost-effectiveness and production efficiency has driven automation manufacturers to integrate PLC-based applications and systems with external networks, such as Internet. Unfortunately, this connectivity has exposed systems to potential malicious attacks from motivated adversaries. Addressing this pressing issue necessitates a comprehensive summary of ongoing research related to PLCs and their related systems. This summary should classify these systems based on disclosed vulnerabilities, potential threats, and proposed security solutions, catering to both scientists and industrial engineers. While several recent surveys have reviewed and discussed PLC security and related topics, they often fell short of covering all essential aspects comprehensively. Furthermore, prior surveys tended to focus on analyzing vulnerabilities at the system level, overlooking the vulnerabilities specific to PLCs themselves. Consequently, their findings failed to effectively secure current operational systems or propose improved solutions for future PLC designs. In this article, we bridge this research gap by providing a detailed review of all aspects concerning the security of PLCs and related systems. This includes vulnerabilities, potential attacks, and security solutions including digital forensics. We aim to offer a precise analysis, addressing the shortcomings of previous studies. Finally, we conclude this article by presenting our recommendations tailored for PLC manufacturers, researchers, and engineers. We hope that these recommendations will contribute to the development of more secure PLCs in the future.}, language = {en} }
