American gun manufacturer Smith & Wesson’s online store has been compromised by attackers who have injected a malicious script that attempts to steal customer’s payment information.¬†This type of attack is called Magecart and is when hackers compromise a web site so that they can inject malicious JavaScript scripts into ecommerce or checkout pages. These scripts then steal payment information that is submitted by a customer by sending it to a remote site under the attacker’s control.
