GCMAN is a threat group that focuses on targeting banks for the purpose of transferring money to e-currency services.
Disclaimer: We present this mapping to stimulate thinking about active defense options to combat this adversary, not to present all possibilities. We invite you to use this as a guide and add your own use cases for applying Shield techniques to counter each adversary action.
Note: All ATT&CK Group sub-technique mappings have been remapped to their parent technique and were derived from Group Technique mappings in ATT&CK v8.
ATT&CK Technique | Opportunity Space | AD Technique | Use Case |
---|---|---|---|
T1021 - Remote Services | There is an opportunity to monitor network traffic for different protocols, anomalous traffic patterns, transfer of data, etc. to determine the presence of an adversary. | DTE0027 - Network Monitoring | The defender can implement network monitoring for and alert on anomalous traffic patterns, large or unexpected data transfers, and other activity that may reveal the presence of an adversary. |
T1021 - Remote Services | In an adversary engagement scenario, there is an opportunity to introduce decoy systems that can influence an adversary's behavior or allow you to observe how they perform a specific task. | DTE0017 - Decoy System | A defender could implement a decoy system running a remote service (such as telnet, SSH, and VNC) and see if the adversary attempts to login to the service. |
