BlackCat ransomware gang listed Conforama, said to be Europe's second-largest home furnishing retail chain, on its victim list.
On its data leak site, BlackCat threat actor boasts about stealing over 1TB of Conforama's data due to "a very low level of security and protection of their users' data."
On November 10, the ransom gang gave Conforama 48 hours to contact them and "get a chance to recover your data and protect your customers from the leak."
The stolen data allegedly contains financial documents and reports, customer credit card data, marketing, analytical and strategic, logistics documents, and client personal information, among other sensitive information.
"If Conforama does not contact us within 48 hours of the attack, this blog will be published, all data will be posted to the public domain, and there will be activity that will severely harm Conforama, its customers, and partners," BlackCat threatened.
It also said it would use clients' financial data for illegal purposes and inform all customers, partners, and suppliers. BlackCat threatened to send all internal marketing and analytical data to Conforama's competitors.
"This is the only chance they have to save their reputation, their business, and their customers' and partners' data," its data leak site reads.
As proof, BlackCat posted over a dozen of company documents, mostly various commercial agreements.
