(Reuters) - Australia's Woolworths Group Ltd said on Friday its majority-owned online retailer MyDeal identified that a "compromised user credential" was used to access its systems that exposed data of nearly 2.2 million users.

The news comes just weeks after Australia's second-largest mobile phone operator Optus suffered a breach that compromised data of up to 10 million customers - one of the biggest such incidents - triggering an overhaul of the country's consumer privacy rules.
