MITRE Caldera OT stands out mainly for being an open-source tool that allows the simulation of different cyber-attacks in industrial environments. This tool was created by MITRE and CISA (US Cybersecurity and Infrastructures Security Agency), as the experts saw the need to be able to improve and understand cybersecurity in industrial environments without using a high number of resources.

In addition, this tool is designed to be used by both the Red Team and the Blue Team, allowing both teams to collaborate with each other to improve the level of cyber security in these environments.

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.
