There has been a security breach. What should I do?
Attacks against your systems and networks can happen at any time, to any person or business. The effects can be devastating, often crippling productivity and exposing sensitive data.
There are some ways to tell if there was an attack on your systems and network:
- You notice unusual activity on your systems, network or files, or you cannot access them.
- Your computer or network is slower than normal.
- People are receiving suspicious emails that appear to be from you or your company.
- You have received a ransom to decrypt your data or prevent it from being leaked or sold online.
