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 651 and after the incident was 485 with a difference of -166 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 CyrusOne and their customers.
Louisiana Office of Technology Services recently reported "Louisiana State Servers Disabled and CyrusOne Hit by REvil Ransomware", a noteworthy cybersecurity incident.
Louisiana’s Office of Technology Services temporarily disabled state servers to prevent ransomware spread, disrupting email, websites, and online applications.
The disruption is felt across the environment, affecting State servers (Louisiana), managed service customer devices (CyrusOne), and exposing Files encrypted (data exfiltration possible).
In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Temporary server shutdown (Louisiana); isolation of affected systems (CyrusOne).
The case underscores how Ongoing.
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.
