The First Signs That Your Data Security Has Been Breached.

Your contacts or customers suddenly start to receive spam emails from your account.

Have you received complaints about an excessive amount of email traffic coming from your account?

What should I do next?  Check your task manager or network for anything suspicious. Run or download your security software to check for malware or viruses.

If you notice unusual internet speed, it may be a sign that your network has been hacked. Hackers often steal bandwidth to carry out their attacks, therefore a reduction your connection speed may indicate a data breach.

Programmes have been installed that you have not authorised.
