Today, one of the most critical, but least known, procedures in industrial security is the secure development. This article gathers all the best practices for the creation of specific applications and equipment for industrial environments in a secure manner. Security aspects that must take into account both the work done during the design (confidentiality of the company and customers, workers' security...), and the security that the designed product itself must present throughout its life cycle (vulnerability management, access control, input/output management...).
The aim of this article is to address the good practices of secure development, from the perspective of industrial cybersecurity. Although traditional best practices can be applicable to these environments, the fundamental aspects of safety and availability generate different approaches, mainly in aspects related to memory and resource management, update and patch management cycles, etc.
Babuk Tortilla is a version of the original Babuk ransomware, which emerged after the leak of its source code, and which attracted attention in the cybersecurity landscape due to the intention of being deployed on vulnerable servers.
This article reviews its origin and operation, focusing on its modus operandi and the techniques used to breach the security of data and systems. It also provides key tools and recommendations to identify and neutralize its effect on technological infrastructures, providing users with the necessary knowledge to defend against this significant risk. Understanding how Babuk Tortilla works and its recovery mechanisms is vital.
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.
