At this time it is unknown how many Australian accounts have been affected and the ACSC continues to monitor the situation closely.
The ACSC suggests Australians who hold a Starwood Hotels and Resorts account should consider monitoring financial accounts for suspicious transactions, especially during the period the data breach took place.
Contact your bank immediately if you suspect any fraudulent activity.
Further information on the breach is available from the Marriot Statement.
Marriott has not approached the ACSC for assistance.
