The subscription site for Forbes magazine has been the victim of the card-skimming attack group Magecart, with the well-known website leaking card data on Wednesday until the attack was noticed and the site taken down.

Malicious attackers have used the GitHub code repository for hosting credit card skimmers which are known as Magecart, the security firm Malwarebytes says, adding that new e-commerce websites are being attacked every day.

Customers of Dutch clothing company OppoSuits have been warned to monitor their credit card accounts after the firm reported that malware planted on its website could have stolen the details of customers who made purchases from its Australian, Canadian, EU and UK websites.
