Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| macos:unifiedlog | process: code or jetbrains-gateway launching with --tunnel or --remote | DC0032 Process Creation |
| macos:unifiedlog | creation of ~/.vscode-cli/code_tunnel.json | DC0039 File Creation |
| NSM:Flow | HTTPs connection to tunnels.api.visualstudio.com | DC0082 Network Connection Creation |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
ParentProcessName | Helps scope tunnel launch context to non-interactive or suspicious parent processes. |
RemoteTunnelPersistence | Allows tracking of tunnel re-establishment across reboots for persistence. |
RemoteFlag | May include values like --remote, -R, or embedded ssh arguments passed by IDEs |
LaunchAgentPath | If the IDE uses persistence via LaunchAgents, defenders may choose where to monitor for tunnel auto-launching |
TunnelReconnectInterval | Frequency of retry attempts for tunnel reconnection can affect correlation window |
