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 757 and after the incident was 747 with a difference of -10 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 Microsoft_SharePoint and their customers.

Microsoft recently reported "Critical SharePoint Server Flaw Enables Unauthenticated Remote Code Execution", a noteworthy cybersecurity incident.

Security researchers at Rapid7 Labs have disclosed a severe vulnerability in Microsoft SharePoint Server, tracked as CVE-2026-63520, which allows attackers to execute malicious code remotely without authentication.

The disruption is felt across the environment, affecting Microsoft SharePoint Server, Microsoft Project Server, Office Web Apps Server.

In response, moved swiftly to contain the threat with measures like Apply security updates/patches, and began remediation that includes Audit SharePoint deployments, verify patch levels, monitor Business Connectivity Services for suspicious activity.

The case underscores how teams are taking away lessons such as Importance of chained vulnerability analysis in uncovering deeper architectural weaknesses in enterprise platforms, and recommending next steps like Apply all relevant patches immediately, audit SharePoint deployments, verify patch levels, and monitor Business Connectivity Services for suspicious activity.

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.
