Dear MICROS Customer,
Oracle Security has detected and addressed malicious code in certain legacy MICROS systems. Oracle's Corporate network and Oracle's other cloud and service offerings were not impacted by this code. Payment card data is encrypted both at rest and in transit in the MICROS hosted environment.
To prevent a recurrence, Oracle implemented additional security measures for the legacy MICROS systems. Consistent with standard security remediation protocols, Oracle is requiring MICROS customers to change the passwords for all MICROS accounts.
Information for customers on how to change your passwords has been published on My Oracle Support (Doc ID 2165744.1).
Those documents have been downloaded for you and you can find them attached.
