The cooperative group in the UK released its interim financial result reports for the first half of 2025 with large -scale losses in operating benefits of £ 80 million ($ 107 million) due to suffering cyber attack last April.
The impact is analyzed in two categories, ie £ 20 million in one-clinical costs and £ 60 million from lost sales while the system offline.
The cyber security incident led to a reduction in revenue of £ 206 million ($ 277 million). The co-op says that it expects a loss of another £ 20 million for the second half of the year, as the recovery will continue.
Cum-ups are cooperative groups owned by a large member of the UK who are active in food retail, life services and business-to-business services. It operates 2,300 food retail stores and 59 franchise stores.
At the end of April 2025, the group discontinued parts of their IT system after detection of hacking attacks, causing limited disruption in back-office and call-sensor services.
A few days later, the co-op confirmed that it was targeted by hackers associated with the dragonforce ransomware operation, which managed to steal the personal data of the current and previous members in large numbers, including the name and contact details.
The attack, blamed the scattered spider colleagues, forced the co-op to rebuild their Windows Domain controllers and further expand the unavailability of the system.
On 10 July, the UK’s National Crime Agency connected four young suspects (age 17-20) to co-up cyber attack, as well as Marx and Spencer and Herods that were around the same period.
On 16 July, cum-up published new details on its internal investigation, stating that hackers stole personal data of all 6.5 million members during the April Cyber attack.
Although the co-opin reaction to the attack was quick and the attempted encryption was prevented, the group faced a significant financial impact.
