Intermarché and French retail data breaches

Overview

In early August 2026, the French retailer Intermarché confirmed that its Drive online‑shopping service had been hit by a cyberattack, exposing personal details of approximately 287,600 to 300,000 customers. The compromised information included names, birth dates, addresses, phone numbers, loyalty‑card numbers, and order details. Banking data, passwords, email addresses, and loyalty‑point balances remained untouched.

Intermarché reported the incident to the French data‑protection authority (CNIL) and filed a criminal complaint with the Paris prosecutor’s office. The prosecutor subsequently opened an investigation for “illegal access to an automated data system,” assigning the case to the city’s cybercrime brigade. Affected shoppers were notified by e‑mail and warned to remain vigilant against phishing attempts.

By late August, the security incident was contextualized within a broader trend of attacks on the French retail sector. In addition to the Intermarché breach, competitor E.Leclerc reported a data breach via its customer service manager, LCommerce, following a cyberattack on an external logistics partner. That breach exposed names, email addresses, and phone numbers, though sensitive banking and login credentials were reportedly not affected.
