Tel Internet Company - One.
Net often receives complaints from customers and third parties regarding hack attempts.
In most cases, these are based on reports from personal firewall products that define certain network connections as hack attempts. Unfortunately, such activity is now common place on the Internet. In addition, within Australia, there are not currently any laws against such activity. This is in part because there is no way to clearly identify whether such activity is hostile or not. Ensure each system you have that is connected to the Internet has all necessary patches and updates installed.
