The programming of PLCs is a fundamental part of the initial phases when building and designing industrial plants. About that environment, the company will base all its operations in that environment making the configuration of these controllers a critical element. When it comes to programming these devices there are a series of steps and best practices that take advantage of the native functionalities available and that involve little or no need to resort to a PLC programmer, protecting the device in a simple way with minimum spend on resource.

Article summarising the ICS alerts published during the year 2022 on the INCIBE-CERT website, with emphasis on different indicators, such as criticality, type of attack, etc.

Antivirus is one of the main lines of defence when a user downloads a malicious file or an attacker has gained access to the computer and attempts to execute malware. Cybercriminals use various means to avoid an antivirus, using different tools and techniques depending on their type and functionalities. This article details the techniques commonly used, as well as the protective measures we should take to prevent attackers from executing malware on our computers.

The increase in industrial control systems and the shortcomings of those systems in cybersecurity measures have made such systems a preferred target of attacks. The number of tools designed to pose a threat to the OT sector has increased, and the use of the Incontroller tool is especially concerning.

PLCs, or Programmable Logic Controllers, have been part of industrial environments since the birth of automation. Given their evolution over time, thanks to greater intelligence, they have become a target of interest for potential attackers.

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.

Weaknesses in TCP protocol implementation in middleboxes could provide a means to carry out distributed reflection denial-of-service (DrDoS) attacks against any target.

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

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.
