Australian retail giant Woolworths revealed on Friday that a recent data breach has impacted the information of 2.2 million MyDeal customers.
Woolworths acquired 80% of the MyDeal online marketplace in September, but says MyDeal systems are completely separate from its own systems, which have not been impacted by the incident.
According to the company, a threat actor leveraged a user’s compromised credentials to access the MyDeal customer relationship management (CRM) system.
This gave the attacker access to MyDeal customer data, including name, email address, phone number, delivery address and, in some cases, date of birth. Woolworths said 1.2 million of the impacted customers only had their email address compromised.
“MyDeal does not store payment, drivers licence or passport details and no customer account passwords or payment details have been compromised in this breach. The customer data was accessed within the MyDeal CRM system and the Mydeal.com.au website and app have not been impacted,” the company explained.
Impacted customers are being notified via email. Authorities have also been informed.
News of the breach comes a few weeks after Australian telecommunications company Optus disclosed a cybersecurity incident impacting nearly 10 million individuals, including 2.1 million who had numbers associated with their identification documents compromised.
