This post presents some lines of action that should be followed to deal with a DrDoS cyberattack based on the SSDP protocol, describing in detail the prevention, identification and response phases to follow.

Technology adoption in industrial plants is part of the global digital transformation. This evolution provides greater knowledge of all the elements that interact in industrial processes, but it can also incorporate cybersecurity issues if a series of good practices are not followed. The development of this article focuses on the problems introduced by Wi-Fi communications and their growth in industrial environments.

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.

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

The industrial environment, especially the energy sector, is one of sectors that is suffering the most from cyber-attacks. This trend has been increasing in recent years, as this is one of the most information-sensitive sectors and can cause major problems, both economically and socially.One of the best examples of malware attacks is BlackEnergy. This malware became known for being able to compromise several electricity distributors on 23 December 2015, causing households in the Ivano-Frankvisk region of Ukraine (a population of around 1.5 million) to be without electricity.For this reason, due to seriousness of this type of cyberattacks, it is necessary to continue researching and investing in industrial cybersecurity, to reduce the damage caused by this type of cyber-attack in industrial environments.

IoT networks are very useful for everyday life, but their use is not limited only to this type of environment; there are industrial environments where this type of networks can benefit connectivity between industrial devices and provide capabilities that other types of networks could not. The 3rd Generation Partnership Project or 3GPP developed the NB-IoT protocol, a protocol for when networks with higher performance, higher speed and high interconnectivity capacity between devices are required. This protocol can work both in IoT devices and in IoT devices in the industrial environment (IIoT).

Article summarizing the Industrial Control Systems (ICS) alerts published during the year 2023 on the INCIBE-CERT website, with emphasis on different indicators, such as criticality, type of attack, etc.The motivation is to give the published notices an added value, in order to compile the information of the whole year as a logbook. In addition, this type of article was well received in previous years, showing in several talks the graphs of the article to argue the exponential growth of vulnerabilities in ICS. 

The OPC UA (OPC unified architecture) communication protocol is the most modern standard presented by OPC Foundation. Currently, the OPC UA protocol is one of the most widely used in industrial environments, due to its ability to interconnect different devices, regardless of their base protocol and vendor.Throughout this article, a technical assessment of the protocol will be conducted, explaining in detail the technical capabilities that allow a high level of cybersecurity to be implemented without causing performance losses in the devices.
