Intermarché Hackers Took Advantage of Mestdagh Brand Take-over-phase

Dozens of former Mestdagh supermarkets of Intermarché fell victim to a cyber attack last Sunday. For some stores this led to supply problems.

Cybercriminals targeted the former Mestdagh supermarkets that were taken over by Intermarché on Sunday – and whose IT systems were not yet fully integrated with those of the Musketiers. The attack was mainly aimed at the internal ordering system. The attackers also demanded a ransom , L'Echo reports.

"Not all stores were affected in the same way. The most significant impact of this cyberattack was on internal order flows and in some cases had repercussions on deliveries, causing supply problems. However, there were no leaks of personal data," said an Intermarché spokesperson. Stores, in Waterloo in particular, reflected supply disruption on the shelves.

Everything should be back to normal by Friday at the latest, says the retailer, who has filed a complaint.
