This post explains the infrastructure of command and control (C&C), describing what an attack consists of, related terminology, actions undertaken by attackers, models, general function and preventative measures, detection and response to this threat.

Demilitarized zones, also known as DMZs (demilitarized zones), are used for the secure exchange of information between computers on a network that we want to protect and an external network that needs to access those computers. DMZs are widely used in the IT sector and also in the OT sector, but the equipment and services they host are not exactly the same.
In recent years, the concept of machine learning has gained more prominence, mainly driven by advances in parallel computing capacity. More and more developments, applications and programs are using these algorithms to provide systems with greater security, intelligence and independence. However, it’s rarely used in industrial environments, although some recent tests and developments prove its effectiveness, including in the scope of detection and prediction of cyber attacks.
Grandoreiro, also known as Delephant, is a banking trojan from South America, which has spread its operations to other regions, especially Europe, including Spain and Portugal. According to ESET researchers, it has been active since 2015, affecting countries in Latin America, mainly Brazil, where it was developed.
The security of control systems can be threatened from different aspects, with the end device being the most important attack vector. With this in mind, the IEC, within the 62443 standard, wanted to emphasise devices by preparing a document exclusively concerning their security: IEC62443-4-2. This document contains different technical requirements to improve the security of the types of assets that can be found in a control system.
The continuity of the production process in businesses that require industrial automation depends more and more on the proper functioning, safety and reliability of the system of that composes it. Therefore, conducting tests of acceptance of its operation prior to its commissioning, is vital to ensure that the systems acquired meet the requirements set out in the contract between the company and the manufacturer.
An adequate level of cybersecurity and cyberresilience is essential to keep assets safe from possible cyberattacks. This is why INCIBE-CERT has listed a set of measures and good practices that are valid for any need that affects cybersecurity.
Standard 62443 arose as a development the ISA 99 standard to fully cover security within control systems. Divided into several parts, each refers to different aspects related to security. The IEC 62443-3-3 standard refers to system security requirements and security levels.
This post will analyse the vulnerabilities associated with Log4Shell, detected in the library Log4j, which is found in infinite software products both in technical and industrial fields. Although there have been other instances of more sophisticated vulnerabilities, the problem with this one is area of exposure.
Monitoring and analyzing security incidents in Industrial Control Systems (ICS) has been a priority for many organizations for a while now. As a response to this need, and given the great success in other areas specialized in cybersecurity, the MITRE organization has developed a matrix that collects many of the tactics, techniques and procedures detected in the industrial world. This article seeks to make the contents and potential uses of said matrix known.
