MITRE ATT&CK

Techniques & procedures

4 distinct techniques documented for this family, organized by ATT&CK tactic.

Discovery

1 technique

T1082System Information DiscoveryEvidence2

GoGRPC then begins a system fingerprinting process by executing the following commands... These commands retrieve information about the victim’s Windows system, including the Windows version and current build.

Command and Control

3 techniques

T1071Application Layer ProtocolEvidence2

GoGRPC uses gRPC over HTTP/2 to communicate with C2 servers... The proxy opens a WebSocket connection over TLS to a hardcoded C2 server.

T1090ProxyEvidence2

The threat actor also deploys SOCKS proxy tools that also use gRPC or WebSockets to communicate with the C2 server.

T1105Ingress Tool TransferEvidence1

the threat actor launches a PowerShell command that downloads and executes GoGRPC... In the initial stage, the threat actor downloads additional PowerShell scripts tailored for corporate environments.
