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 industrial environment, especially the energy sector, is one of sectors that is suffering the most from cyber-attacks. This trend has been increasing in recent years, as this is one of the most information-sensitive sectors and can cause major problems, both economically and socially.One of the best examples of malware attacks is BlackEnergy. This malware became known for being able to compromise several electricity distributors on 23 December 2015, causing households in the Ivano-Frankvisk region of Ukraine (a population of around 1.5 million) to be without electricity.For this reason, due to seriousness of this type of cyberattacks, it is necessary to continue researching and investing in industrial cybersecurity, to reduce the damage caused by this type of cyber-attack in industrial environments.

IoT networks are very useful for everyday life, but their use is not limited only to this type of environment; there are industrial environments where this type of networks can benefit connectivity between industrial devices and provide capabilities that other types of networks could not. The 3rd Generation Partnership Project or 3GPP developed the NB-IoT protocol, a protocol for when networks with higher performance, higher speed and high interconnectivity capacity between devices are required. This protocol can work both in IoT devices and in IoT devices in the industrial environment (IIoT).

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.
