The M-Bus protocol is a common protocol in the industry in general, it’s daily use can be related to devices for measurements of electricity, gas, water, heating, etc. This protocol has a wireless variant called Wireless M-Bus and works through a hierarchical master/slave system, standardized according to EN13757.

Space is an increasingly important element in the critical infrastructures of all countries. The possibility of losing or degrading space services can significantly affect both national security and all customers who have contracted services involving the use of satellites or any other space devices, resulting in major economic and security losses.To protect it, the National Institute of Standards and Technology (NIST) has developed a cyber security framework for the commercial ground segment of the space sector, providing a means for stakeholders to assess their cyber security posture in terms of identification, protection, detection, response and recovery operations, thereby evaluating the level of risk to the satellite ground segment structure.

In the electricity sector, it has always been necessary to use robust communications that allow proper communication, since a failure in this sector would cause a large number of losses, both economic and social.In addition, with the technological advances, it is important also to have secure communications since the electricity sector is one of the sectors that currently suffers the most cyber-attacks. For this reason, in recent years different robust and secure protocols have been created.One of these protocols is DNP3, created mainly for the use of substation automation and control systems, for the electric utility industry, although it has now also been used for other sectors.Finally, in this article we want to explain in more depth the operation of this protocol and the benefits or disadvantages of using this protocol.

CAPEC (Common Attack Pattern Enumeration and Classification) is a project that focuses on enumerating and classifying common attack patterns on computer systems and providing a systematic approach to understanding and addressing the tactics used by attackers. Like CWE (Common Weakness Enumeration), CAPEC is an initiative of the computer security community and is maintained by the National Institute of Standards and Technology (NIST) in the United States. Recently in version 3.9, the project has incorporated a number of attack patterns related to the industrial world.This article aims to show the reader the use of these codes, such as those used at the identifier level in CVEs, CWEs, etc., and which are related to many of the jobs that are carried out on a daily basis in the industrial cybersecurity sector.

Since its appearance in 2022, Black Basta has established itself as one of the most dangerous ransomwares in the current landscape, standing out for its ability to carry out double extortion attacks, stealing and encrypting data from its victims. Although it focuses on Windows systems, versions for Linux systems that attack ESXi hypervisors have also been discovered. At the end of December 2023, a renowned ethical hacking lab in Berlin published a decryption tool on GitHub to combat it. Although the group has recently updated its software to fix this flaw, the release of the decryption tool represents a major blow against its operations. In this article, we take a closer look at how this ransomware works, exploring the methods it employs to compromise the integrity of data and systems and presenting the decryption method for its vulnerable version.

The automotive world has always been one of the most cutting-edge sectors in terms of the technology used, which is why today's cars are equipped with technologies such as Bluetooth, NFC, GPS, etc., which improve different aspects such as comfort, fuel efficiency and increased safety.But these implemented technologies can also bring with them serious problems, such as the risk of cyber-attacks that can affect passengers in the vehicle, both at the level of personal data and physical security.For this reason, this article aims to provide an insight into some of the cyber-attacks that smart cars have suffered and how cyber-security is evolving and adapting to make more and more vehicles cyber-safe.

Currently, industrial infrastructures are suffering more attacks than ever before, and it is expected that attacks on these types of infrastructures will continue to grow exponentially in the coming years. This is why, throughout this article, an analysis will be made of a group of cybercriminals and their standard attack, showing how information can be obtained on the modus operandi, when and by what tactics and techniques they managed to attack an industrial infrastructure

LockBit ransomware has rapidly evolved to become one of the most prolific threats of our time. Its technical sophistication, evidenced by the development of tools, such as StealBit, for automated data exfiltration and its adaptation to attack Linux servers, specifically ESXi, demonstrate the advanced adaptability and potential impact on affected organizations.In addition, the implementation of a ransomware-as-a-service (RaaS) model and double extortion tactics underscore the complexity and coercive nature of their campaigns. The response to this threat, however, has culminated in a collaborative law enforcement effort that has succeeded in dismantling LockBit's infrastructure, leading to the arrest and indictment of several of its operators. In this article we focus on the version of LockBit 3.0, presenting its main features and the current tools for recovering data in case it has been compromised.

Within the framework of RPKI security infrastructures, ROAs are crucial components in the defense of cyberspace, providing authentication and verification mechanisms for routes vital to the security of Internet routing. Despite its undeniable benefits, creating and maintaining ROA has its own set of challenges and considerations. This article explores the relevance of ROAs, examines their inherent challenges, and underscores the importance of secure implementation and management to strengthen Internet resilience.
