Hundreds of French supermarkets belonging to the Intermarché and Coopérative U chains have fallen victim to a cyberattack targeting their refrigeration systems, the two retail giants said on Monday.
Around 150 to 200 Intermarché stores were hit, along with nearly 100 Coopérative U outlets, they added. The Paris prosecutor's office confirmed the cyberattack, which is also thought to have affected other major chains.
