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.

Ransomware, one of the top cybersecurity threats in today's landscape, allows criminals to hijack data and demand ransoms. Although there are various families and variants, some are especially destructive. These cybercriminals have refined their methods, using everything from complex extortion to bug bounty-type programs. In the face of these challenges, we will explore tools and strategies to recover from and defend against such attacks.

The  Hive ransomware (especially in its v5 version) stands out for its sophistication, and for the impact caused to hundreds of companies and organizations worldwide, bypassing conventional defenses and challenging analysts with its advanced techniques.

In this article, we unravel its features, from its encryption methods to its anti-analysis countermeasures, illustrating not only the threat it poses, but also how it can be combated. Through a technical analysis, it is intended to empower readers with the knowledge necessary to understand and ultimately defend against these types of threats.

The Border Gateway Protocol (BGP) is fundamental to the functioning of the Internet as we know it, as it serves to route data flows along the optimal routes, through several different hops (or IPs). However, it was not designed with security by design, which opens the door to hijacking BGP-type  threats. 

Through these types of attacks, malicious actors can redirect traffic, causing data loss, such as  in Man-in-the-Middle, among others. This article explores in depth these types of attacks, their impact, and the countermeasures available through mechanisms such as RPKI, IRR, and ROA.

The increase of malware specifically designed to run on systems that support industrial processes creates a need in the industry that can be partly covered by different technological solutions. This article will focus on the different options available on the market to detect malicious files that aim to modify the operation of industrial environments or simply cause denials of service.
Both portable and agent-deployed solutions can be an option, and this article will reflect on these and other options as well as provide guidelines on when it is best to use one solution or the other.

The Purple Teams are exercises in which three very well differentiated teams participate: a Red Team, a Blue Team and a Purple Team. The Red Team will be in charge of carrying out attacks on the defined structure, the Blue Team will be the team in charge of defending that structure and the inclusion of the Purple Team allows the two previous teams to communicate with each other and be organized correctly thanks to the work of the purple team. This is why the Purple Teams allow a great number of advantages to be obtained with respect to carrying out the exercises separately and without coordination between them.
This article presents all these advantages and much more about Purple Teams.

When talking about an endpoint device, we are talking about an end asset present at the network level. Among these devices we can find engineering stations (workstations), HMI, SCADA or PLC, among others.

 The evolution of industrial environments towards models in which these equipment are connected, both with corporate networks and remotely with suppliers, for maintenance purposes, exposes them to new threats. That is why industrial endpoints must be properly and individually protected and at multiple levels so that they cannot be compromised.   These end systems are key security hotspots because their vulnerabilities could affect other assets within the network.
