What happens if I am hacked?

Not anything good. You will need to call a professional who is experienced in remediating compromised networks.

Everything has to be checked, cleaned, and verified. All breaches have to be reported to the authorities and documented. You are now exposed to liability and compliance issues regarding what was stolen. Your business and livelihood are now at risk due to down time, loss of income, and loss of customer trust.

If a ransom demand is made, do not respond until consulting a qualified professional. More than 62% of companies that pay the ransom are hacked again by the same group.
