After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 781 and after the incident was 675 with a difference of -106 which is could be a good indicator of the severity and impact of the incident.
In the next step of the video, we will analyze in more details the incident and the impact it had on DNV - Maritime and their customers.
On 07 January 2025, DNV disclosed Ransomware issues under the banner "Major Ransomware Attack Disrupts Global Supply Chain Operations".
A large-scale ransomware attack has targeted DNV, a leading provider of maritime software solutions, forcing the company to shut down key IT systems affecting 70 ship management clients worldwide.
The disruption is felt across the environment, affecting ShipManager software (navigation, maintenance, compliance systems).
In response, moved swiftly to contain the threat with measures like Shut down key IT systems; activated backup systems.
The case underscores how Ongoing, teams are taking away lessons such as Growing vulnerability of maritime infrastructure to cyber threats; escalating risks to supply chains due to interconnected digital systems.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
