This article introduces how ESXiArgs operates, and offers an approach to identifying and addressing the threat. Examining the characteristics and behaviours of ransomware, it provides detailed insight into the tactics it uses and how these can be detected in a vulnerable environment. It also explores strategies and best practices for cleaning and disinfecting compromised systems, restoring trust and security to the affected infrastructure.
Firmware analysis can help to uncover potential vulnerabilities that would otherwise never have been discovered.
Although there are multiple types of attacks on IoT and IIoT devices, this guide focuses on the firmware of these devices to check for potential vulnerabilities, using security testing and reverse engineering to allow for an in-depth analysis of the firmware.
With this study, we seek to offer a deep knowledge about the reconnaissance activity in cybersecurity, so that professionals from different fields can consider these tactics as an integral part of their security strategies. This study also aims to increase general understanding of these techniques and how they can be used to effectively protect information and systems.
Within the industrial world, systems can be detected that do not have all their cybersecurity capabilities activated. This can occur for a variety of reasons, but if detected, each case must be analyzed to get the most out of each device.
The ability to robustly configure programs, services or other nuances within industrial systems is called bastioning and allows, among other things, to prevent assets from having a large exposure to the network or the solutions deployed in the system from having vulnerabilities resulting from misconfiguration.
In this article, we will begin by explaining what hardening is and how to apply it to our industrial network, along with some good practices to follow.
