The threat group known as “RedCurl APT” 🔴 has been observed employing an unusual tool, “Active Directory Explorer” 📂, in their attacks. They are utilizing this legitimate utility for reconnaissance and the exfiltration of sensitive information from systems utilizing Active Directory.
Reason: RedCurl APT is likely using Active Directory Explorer because it is a legitimate tool commonly found within organizational systems for administrative purposes. This allows them to blend in with normal network activity and evade detection by traditional security software 🛡️, as their actions may appear to be those of authorized system administrators.
Solutions:
- Closely monitor the usage of Active Directory Explorer within your organization. Look for any unusual activity or unauthorized access to sensitive information.
- Restrict access to Active Directory Explorer to only those users who require it for their job functions 🔒.
- Implement Behavioral Detection Tools to help identify suspicious activities associated with the use of this tool 🧐.
- Educate employees about the tactics and techniques employed by the RedCurl APT group 📚.
Adversary’s Method: The RedCurl APT group first gains unauthorized access to the target organization’s network. Once inside, they utilize Active Directory Explorer to map the Active Directory structure, identify privileged user accounts, and locate resources of interest 😈. This information can then be used to move laterally within the network, steal sensitive data, or carry out further malicious activities.
News Analysis: The use of Active Directory Explorer by RedCurl APT indicates a sophisticated understanding of organizational IT infrastructure and a trend towards leveraging existing, legitimate tools for malicious purposes 🧐. This tactic makes detection more challenging and highlights the need for robust security measures and continuous monitoring of network activity to defend against such advanced threats.
