ZGrab2 integration is experimental and porting is currently not complete. You can help adding modules and improve stability.
ZGrab2 is an awesome application layer scanner. Since it is supposed to run standalone and doesn’t provide an API, integration into nray requires some glue code for each module to work.
Nray’s ZGrab2 integration uses a subscription-based approach for performing application layer scans. Suppose the following configuration:
ssh: subscribePorts: ["tcp/22", "tcp/222", "tcp/2222"] timeout: 2500ms
Here, an SSH application layer scan with its own timeout of 2500ms is triggered every time an open port
tcp/2222 is found.
Nray’s ZGrab2 integration runs also concurrent to other scans, using the worker pools and rate limits assigned in the scanner configuration. The result produced are also in JSON format and fit into the events produced by nray’s port scanning functionality.
Which ZGrab2 modules to enable. Currently, the following modules are supported:
