Predefined variables

Tsunami will provide a predefined set of variable to the environment that you can make use of in your actions. We try to maintain a strong naming convention for these :

• T_ stands for Tsunami and identifies a variable that is provided by the core engine;
• _UTL_ stands for utility and provides various utility variables;
• _NS_ stands for network service and provide information about the currently scanned network service;
• _CBS_ stands for callback server and provides information about the callback server.

Here is the list of variables that are provided:

• T_UTL_CURRENT_TIMESTAMP_MS: Provides the current timestamp in milliseconds. Note that the timestamp is computed at the beginning of a workflow run. It will thus be different between services but always return the same value within one run;
• T_NS_BASEURL: The base URL of the network service being scanned. For example http://127.0.0.1:9090 or http://hostname.lan:1000;
• T_NS_PROTOCOL: The protocol used by the network service being scanned (e.g. tcp);
• T_NS_HOSTNAME: The hostname of the network service being scanned. Note that this variable is only available if Tsunami was invoked with a hostname target (e.g. hostname.lan);
• T_NS_PORT: The port of the network service being scanned (e.g. 1000);
• T_NS_IP: The IP of the network service being scanned (e.g. 127.0.0.1);
• T_CBS_URI: The callback server URL used to trigger the callback server. This is the main variable used when using the callback server. It contains the address and hashed secret (e.g. http://tsunami-callback.lan/8fe7d878787d65 where 8fe7d878787d65 is the hashed secret);
• T_CBS_SECRET: The callback server secret generated for the current workflow run; note that it is not hashed and is not relevant in most cases (e.g. somesecret);
• T_CBS_ADDRESS: Address of the callback server (e.g. tsunami-callback.lan);
• T_CBS_PORT: Port of the callback server (e.g. 80);
