Hackers have attempted to steal credit card information from the owner of Ireland’s most popular supermarket.

Musgrave, which owns SuperValu, Centra, Daybreak and Mace, said on Tuesday that it detected malware on its systems which attempted to steal customers’ card information.

The company claimed the attackers attempted to take credit and debit card numbers and expiry dates, but not the names, PINs or CVV numbers associated with the cards.

While there is no evidence that any data has been stolen at this point, Musgrave is advising any concerned shoppers to review activity on their statements as a precautionary measure, the company said in a statement.

The attack has been reported to the Garda and the Irish Data Protection Commissioner.

Musgrave’s SuperValu stores have more than a fifth of the supermarket share in Ireland.

The company also operates stores in Northern Ireland, and it is understood customers on both sides of the border were targeted in the attack.

Cyber breach response experts are applying advanced technical fixes to deal with the breach, the retail giant added.

In response to questions from Sky News, Musgrave explained that it is still assessing the extent of the hackers’ attempted extraction of customer data.

It said it spotted an extraction attempt on Monday afternoon and does not yet know when it had been compromised by the malware.
