New malware is circulating on the Internet that infects Mac machines and tries to trick users into giving away their credit card data. According to Intego the malicious app called MacDefender hides on some webpages that use search engine optimization to spam the results of popular searches. On such infected websites users can see animation of a malware scam followed by a pop-up message telling users that their computer is infected. JavaScript on the page then automatically downloads a compressed ZIP file containing the malware.
