The UN R155 and UN R156 regulations are of vital importance for vehicle cybersecurity. From July 2022, all car manufacturers that want to be type-approved must comply with both regulations, but from July 2024 this requirement will be extended to all new vehicles sold in the European Union, regardless of when the manufacturer obtained type-approval. One of the most important aspects of compliance with both regulations is the completion of a cybersecurity risk assessment of the vehicle, including all integrated components of the vehicle's supply chain. On the other hand, it also specifies how to incorporate cybersecurity from design, how to detect and respond to incidents, how to securely update vehicle software, etc.

Since its appearance in 2022, Black Basta has established itself as one of the most dangerous ransomwares in the current landscape, standing out for its ability to carry out double extortion attacks, stealing and encrypting data from its victims. Although it focuses on Windows systems, versions for Linux systems that attack ESXi hypervisors have also been discovered. At the end of December 2023, a renowned ethical hacking lab in Berlin published a decryption tool on GitHub to combat it. Although the group has recently updated its software to fix this flaw, the release of the decryption tool represents a major blow against its operations. In this article, we take a closer look at how this ransomware works, exploring the methods it employs to compromise the integrity of data and systems and presenting the decryption method for its vulnerable version.

LockBit ransomware has rapidly evolved to become one of the most prolific threats of our time. Its technical sophistication, evidenced by the development of tools, such as StealBit, for automated data exfiltration and its adaptation to attack Linux servers, specifically ESXi, demonstrate the advanced adaptability and potential impact on affected organizations.

In addition, the implementation of a ransomware-as-a-service (RaaS) model and double extortion tactics underscore the complexity and coercive nature of their campaigns. The response to this threat, however, has culminated in a collaborative law enforcement effort that has succeeded in dismantling LockBit's infrastructure, leading to the arrest and indictment of several of its operators. In this article we focus on the version of LockBit 3.0, presenting its main features and the current tools for recovering data in case it has been compromised.

The Resource Public Key Infrastructure (RPKI) is essential for Internet routing security, as it provides a method to securely connect IP addresses to autonomous systems (AS) by validating route information. 

RPKI effectively prevents BGP Hijacking-type attacks, where potential attackers maliciously redirect Internet traffic. This article aims to explore the design, implementation, and benefits of using RPKI to ensure security and authenticity in Internet routing.

Managing and predicting vulnerabilities has become an essential task for cybersecurity. The Exploit Prediction Scoring System  (EPSS) is a methodology launched in 2019, which uses algorithms and threat intelligence data to predict the likelihood of a specific vulnerability being exploited by threat actors in a short space of time.

In an environment where organizations are faced with an increasing number of vulnerabilities, EPSS effectively prioritizes responses to vulnerabilities based on their risk of exploitation. Through meticulous information collection and analysis, this system offers an efficient view of the threats affecting the business, allowing organizations to act proactively. This article focuses on understanding EPSS, how it improves security posture, and best practices for its implementation.
