The increasing development of malware targeting the industrial world has not halted its momentum in the slightest. Several research groups have detected a new malware called Fuxnet and are currently investigating its scope. This malware has the capability to send specific requests at the serial level, via RS485/MBus, executing floods to more than 87.000 assets, including control systems and integrated sensors deployed across different sectors. Among the infrastructures compromised by this malware, we find hospitals, airports and other critical infrastructures that provide essential services to the population.
MITRE Caldera OT stands out mainly for being an open-source tool that allows the simulation of different cyber-attacks in industrial environments. This tool was created by MITRE and CISA (US Cybersecurity and Infrastructures Security Agency), as the experts saw the need to be able to improve and understand cybersecurity in industrial environments without using a high number of resources.
In addition, this tool is designed to be used by both the Red Team and the Blue Team, allowing both teams to collaborate with each other to improve the level of cyber security in these environments.
In the era of interconnection and digitization, industrial control systems (ICS) are increasingly exposed to cyber threats. These systems are vital for energy production, manufacturing and critical infrastructure management, and their protection has become an essential priority.
Risk analysis is fundamental in this context, as it allows identifying, assessing and prioritizing the risks that can affect ICS. This process, ranges from technical vulnerabilities to emerging threats, and is crucial for developing effective mitigation and protection strategies.
In this article, the challenges and solutions related to risk analysis in ICS will be explored, as well as the importance of the IEC 62443-3-2 standard in this critical process.
The agri-food sector is one of the most critical sectors today because it is one of the most important sectors for the country's economy, as it produces food.
This sector, like many others, is in continuous evolution. An example of this is the automation and digitalization of the many processes that are carried out. These new technologies bring many advantages, such as more efficient processes, less water consumption, detection of possible risks, etc. These great advantages also bring with them some problems, such as increased exposure to cyber-attacks.
Therefore, this article provides some basic knowledge to make the industry aware of the importance of implementing cybersecurity in their technologies.
In the industrial environment, the interconnection of industrial equipment for maintenance via the Internet is becoming increasingly common. However, this has also opened the door to a new and dangerous landscape of threats. This article reviews one of the most representative threats within this current new paradigm, APTs, how concern about this type of threat is increasing, and how they operate during an industrial attack.
UMAS (Unified Messaging Application Services) is a Schneider Electric (SE) proprietary protocol used to configure and monitor Schneider Electric programmable logic controllers (PLCs). While it is true that the protocol is related to this manufacturer, the use of the protocol is quite widespread in different sectors, especially the energy sector, as is obvious.
The article will focus on the technical breakdown of the protocol and the use of the protocol. The article will also show weaknesses, strengths and some technical vulnerabilities detected in this protocol.
The UN R155 and UN R156 regulations are of vital importance for vehicle cybersecurity. From July 2022, all car manufacturers that want to be type-approved must comply with both regulations, but from July 2024 this requirement will be extended to all new vehicles sold in the European Union, regardless of when the manufacturer obtained type-approval. One of the most important aspects of compliance with both regulations is the completion of a cybersecurity risk assessment of the vehicle, including all integrated components of the vehicle's supply chain. On the other hand, it also specifies how to incorporate cybersecurity from design, how to detect and respond to incidents, how to securely update vehicle software, etc.
