Security researcher Aviv Raff has published code that would allow someone to take control of a computer running Internet Explorer. Raff informed Microsoft of the flaw on Tuesday and the software vendor has not yet patched it, Raff said. The hacker would first have to put a small amount of HTML code on a Web site and then persuade the victim to use a specific Internet Explorer feature on that site. The idea of disclosing his attack in a treasure hunt came from a local custom of playing such games during Israel’s Independence Day, which falls Thursday.”]
