OSINT (Open-Source Intelligence) is a technique that focuses on the collection, evaluation and analysis of public information through different methods and techniques, with the objective of discovering vulnerabilities or collecting sensitive information that could become threats.
It should be emphasized that the data collection is not called OSINT, it would be raw information. Once this information is evaluated and treated, it could be said that we are really talking about open-source intelligence (OSINT).
Initially it has been used in the military and government sector. Its use in OT, with disciplines such as SIGINT (Signals Intelligence), IMINT (Imagery Intelligence) or even 'Sock Puppets' (fake profiles or intruders in technical forums) is making havoc due to the criticality of this equipment. Disinformation or the compilation of sensitive industrial technical information are some of the serious consequences that this sector is exposed to.
The Avaddon ransomware appears as a disturbing threat that has demonstrated its ability to exploit vulnerabilities in systems, compromising the security and integrity of critical data.
This article dives into the details of how Avaddon works, while also providing a comprehensive analysis of strategies to detect and mitigate the threat.
The presence of Shadow IT, i.e., the unauthorized or unmanaged use of IT technologies and services by employees, poses challenges and risks of considerable magnitude.
The rapid adoption of personal devices and applications, as well as accessibility to cloud services, have increased the complexity of the security landscape. This situation poses a risk that can compromise the confidentiality and integrity of the organization's information.
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.
