Some signs that you have been attacked:
When you click on an Internet link or download an online file, and you
cannot access your usual files, applications or services.
If you are locked out of your online accounts or receive messages that
your password has been changed when you have not changed it.

grinds to a halt.
So how?

Call your organisation’s incident response team immediately when you
discover the cyber-attack. The team will help the organisation fiat
