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

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.

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

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.

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.

The malicious code of the ransomware known as ‘Hive’ represents a threat to all users, as it implements encryption functionalities on the information in an infected computer, making simple recovery of the data impossible. This threat attempts to use extortion to recover the information, demanding a payment and threatening publication of part of the stolen information on a blog through the network Tor if the payment is not forthcoming.

All organisations must be prepared so that, after the impact of a cyberattack, it may change, improve and adapt its processes and services. For this reason, it is necessary to protect the main business processes using a set of tasks that allow the organisation to evolve after a serious incident to redesign its strategies and minimise the possible impact of future cyberattacks

The new generations of antiviruses may entail an improvement in the OT environment, since special care must be taken with the assets, networks and communications of Industrial Control Systems. They can also help secure our industries against the increasingly frequent cyberattacks directed against them.

It is necessary to protect the main business processes through a set of tasks that allow the organisation to recover from a major incident in a timeframe that does not compromise the continuity of its services. This ensures a planned response to any security breach.
