On 11 June 2024, U.S. federal agencies disclosed Zero-Day Exploit issues under the banner "Critical Zero-Day Exploit in Microsoft SharePoint Targets Government and Corporate Networks".
A newly discovered zero-day vulnerability in Microsoft SharePoint Server (CVE-2024-38021) has been actively exploited in targeted attacks against government agencies and large enterprises, primarily in North America and Europe.
The disruption is felt across the environment, affecting Microsoft SharePoint Server 2016, 2019, and Subscription Edition, and exposing Sensitive data exfiltration.
In response, and began remediation that includes Microsoft out-of-band security update (KB5039210).
The case underscores how Ongoing, teams are taking away lessons such as The incident underscores the growing threat of zero-day exploits in enterprise collaboration platforms, which are increasingly targeted for their broad access to sensitive data, and recommending next steps like Apply Microsoft’s out-of-band security update (KB5039210) immediately. Monitor for post-exploitation activity such as custom backdoors, credential dumping, and reconnaissance tools.
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.
