Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Microsoft_SharePoint breach identified under incident ID MIC1768636894.
The analysis begins with a detailed overview of Microsoft_SharePoint's information like the linkedin page: https://www.linkedin.com/company/microsoft_sharepoint, the number of followers: 0, the industry type: Software Development and the number of employees: None employees
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 769 and after the incident was 767 with a difference of -2 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.
On 19 July 2025, Microsoft SharePoint Server Users disclosed Ransomware and Espionage issues under the banner "Critical SharePoint Vulnerabilities Exploited by Chinese Threat Actors, Leading to Ransomware Attacks".
On July 19, 2025, Microsoft disclosed active exploitation of two critical vulnerabilities in on-premises SharePoint servers (CVE-2025-49706 and CVE-2025-49704).
The disruption is felt across the environment, affecting On-premises SharePoint servers (2016, 2019, Subscription Edition), and exposing Credentials, sensitive data via web shells and lateral movement.
In response, moved swiftly to contain the threat with measures like Apply SharePoint security updates, Enable AMSI in Full Mode and Deploy Microsoft Defender Antivirus, and began remediation that includes Patch SharePoint servers and Monitor for IOCs (web shells, malicious files, C2 domains).
The case underscores how Ongoing, teams are taking away lessons such as Immediate patching and monitoring are critical to preventing exploitation of critical vulnerabilities. Organizations should rotate machine keys and enable AMSI to detect web shell activity, and recommending next steps like Apply SharePoint security updates immediately, Enable AMSI in Full Mode and deploy Microsoft Defender Antivirus and Rotate SharePoint ASP.NET machine keys and restart IIS after patching, with advisories going out to stakeholders covering Microsoft urges organizations to apply patches and monitor for exploitation 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.
