Co-op confirms massive data breach as retail cyberattacks surge

All 6.5 million members of the Co-op had their personal data compromised in a cyberattack carried out on 30 April, the company’s chief executive has confirmed.

Shirine Khoury-Haq said the breach felt ‘personal’ after seeing the toll it took on IT teams fighting off the intrusion. She spoke in her first interview since the breach, broadcast on BBC Breakfast.

Initial statements from the Co-op described the incident as having only a ‘small impact’ on internal systems, including call centres and back-office operations.

Alleged hackers soon contacted media outlets and claimed to have accessed both employee and customer data, prompting the company to update its assessment.

The Co-op later admitted that data belonging to a ‘significant number’ of current and former members had been stolen. Exposed information included names, addresses, and contact details, though no payment data was compromised.

Restoration efforts are still ongoing as the company works to rebuild affected back-end systems. In some locations, operational disruption led to empty shelves and prolonged outages.

Khoury-Haq recalled meeting employees during the remediation phase and said she was ‘incredibly sorry’ for the incident. ‘I will never forget the looks on their faces,’ she said.

The attackers’ movements were closely tracked. ‘We were able to monitor every mouse click,’ Khoury-Haq added, noting that this helped authorities in their investigation.

The company reportedly disconnected parts of its network in time to prevent ransomware deployment, though not in time to avoid significant damage. Police said four individuals were arrested earlier this month in connection with the Co-op breach and related retail incidents. All have been released on bail.

Marks & Spencer and Harrods were also hit by cyberattacks in early 2025, with M&S still restoring affected systems. Researchers believe the same threat actor is responsible for all three attacks.

The group, identified as Scattered Spider, has previously disrupted other high-profile targets, including major US casinos in 2023.
