- How he used it on an assessment:
- He broke into an external network to a router with default credentials
- and the router had a wireless network attached to it that had credentials
- He looked up the SSID to find where that network was.
- Was it a residential? Business address? Where were they using that network?
- On location? Somewhere remote? Would that give you any details?
- If he got on the network, could he get anything of use?
