cotta: possible unauthorized access to the baking supplies online shop

On 26 October cotta, which runs the cotta online shop for baking supplies, said it had found possible unauthorized access to its online shop and is investigating with an outside firm. Whether personal or card data leaked is still under investigation, and nothing has been confirmed. As a precaution it stopped card payments in the online shop, including Yahoo! Wallet, and some web functions from 09:00 on 26 October. No restart date has been set, and customers who paid by card in the past are asked to check their statements.
