Constant Port Scanning attacks


Recommended Posts

  • ESET Moderators

Hello Gabriel,

 

As the origin of the detected attacks is outside your local network, you can remain calm, there is nothing on your network that would cause the behaviour.

Port scanning means some script is checking what ports are open, e.g. vulnerable for attacks. This is not that unusual - if somebody knows you IP address, they can easily send such requests to the address and see which ports respond to requests.

In most cases, these attempts are stopped by a router, but if they went through, our product blocked them.

I recommend to change your external IP address periodically (ask your ISP), or to configure your router to stop these kinds of scanning attempts.

 

Regards,

T.

Those IP addressess trace back to China so I would be vigilant. Also if you don't have a router with NAT & SPI plus a firewall, I would consider investing in one.
