- Cicis Restaurant Chain Data Breach. From Cicics.com. While this matter is still under investigation, we wish to report what we currently know. In early March of 2016, we received notice from several of our restaurant locations that their Point of Sale (POS) systems were not working properly. Our POS Vendor began an investigation to assess the problem and initiated heightened security measures. When the POS Vendor found malware on the POS software at some Cicis restaurants, we immediately began a restaurant by restaurant data security review and remediation.
