Auchan

On June 6 2023 the threat actor group known as NLB leaked a massive customer database belonging to the Auchan retail chain. The breach originated from a compromise that occurred on May 18 2023. The exposed dataset contains millions of unique customer records including contact details and logistical information. This incident is part of a series of attacks by the same group targeting large retail entities operating in the region. The leaked files include detailed order histories and delivery specifications which could be used for targeted phishing or social engineering attacks against the affected customers.
