I have a customer with a Hikvision NVR with email alerts set up to alert to illegal logins. At around 4:00am, there were 2,000 attempts to login to "admin" from IP address 192.168.1.33. The store was closed at the time and due to the extremely high number of attempts I'm sure this was a computer generated attack. Any thoughts on why this is showing a LAN address? Does this mean that whatever PC is 1.33 is suspect? How serious is this and what steps should I suggest to the customer?
