MyDeal, a subsidiary of supermarket giant Woolworths Group, has suffered a data breach, with compromised user credentials being used to gain access to the company's customer relationship management system.

In a statement issued on Friday, Woolworths said 2.2 million customers were affected, adding that it had begun to contact regulatory authorities and government agencies.

The MyDeal site is hosted by Amazon in the US, according to Internet services company Netcraft, and appears to use ASP.NET, technology sold by Microsoft.

As per Microsoft's own site, "ASP.NET is a free, cross-platform, open source framework for building Web apps and services with .NET and C#."

Of itself, MyDeal says: "MyDeal is a leading Australian online retail marketplace that provides customers with quality products from a curated selection of trusted retailers. "Since 2011, we’ve brought Australian shoppers the biggest brands, the best deals, discounts and sales on an extensive range of home and lifestyle products."

Woolworths completed its acquisition of about 80% of on 23 September. "There has been no compromise of any other Woolworths Group platforms or the Woolworths Group customer or Everyday Rewards records," the statement added.

The statement said data that had been accessed included customer names, email addresses, phone numbers, delivery addresses, and, in some cases, the date of birth of customers.

Of the affected customers, 1.2 million had only their email addresses exposed.

Woolworths said the data was accessed within the CRM system and the MyDeal Web site and app were not affected.

"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 statement said.

MyDeal founder and chief executive Sean Senvirtne said: “We apologise for the considerable concern that this will cause our affected customers. We have acted quickly to identify and mitigate unauthorised access and have increased the monitoring of networks.

"We will continue to work with relevant authorities as we investigate the incident and we will keep our customers fully informed of any further updates impacting them.”

Woolworths Group chief security officer Pieter van der Merwe added: “Woolworths Group’s cyber security and privacy teams are fully engaged and working closely with MyDeal to support the response."

The statement said affected customers could contact MyDeal directly or through the company's help centre.

This is the sixth data breach of Australian companies announced in less than a month. Optus announced on 22 September that its systems had been breached, followed by Telstra, G4SCosta GroupDialog and Medibank Group

Hybrid cloud promises to bring together the best of both worlds enabling businesses to combine the scalability and cost-effectiveness of the cloud with the performance and control that you can get from your on-premise infrastructure.

Reducing WAN latency is one of the biggest issues with hybrid cloud performance. Taking advantage of compression and data deduplication can reduce your network latency.

Research firm, Markets and Markets, predicted that the hybrid cloud market size is expected to grow from US$38.27 billion in 2017 to US$97.64 billion by 2023.

Colocation facilities provide many of the benefits of having your servers in the cloud while still maintaining physical control of your systems.

Cloud adjacency provided by colocation facilities can enable you to leverage their low latency high bandwidth connections to the cloud as well as providing a solid connection back to your on-premises corporate network.

Download this white paper to find out what you need to know about enabling the hybrid cloud in your organisation.
