The only comments from MICROS/Oracle at this point is that everyone needs to change their passwords. No word on if any credit card information was compromised.
This brings up a few reminders - no matter what point of sale system you are using:
- Make sure that you are using the most current/recent version of any point of sale software
- Perform regular PCI scans to ensure that everything in your business is PCI compliant
- No actual credit or debit card information should be flowing through the system as regular numbers
- Make sure that you have business class computer equipment as well as anti-virus and malware software that is always scanning and always updating
