A computer security firm has found a flaw in Microsoft’s Internet Explorer browser that allows hackers to steal credentials to access Facebook, Twitter, and other websites. The technique is called cookiejacking, an abbreviated form of cookie-hijacking. Once the hacker has the cookie, he or she can use it to gain access to the same website.
The vulnerability currently affects all versions of Internet Explorer on every version of Windows operating system. Hackers can exploit the flaw to access a data file, called a cookie, that holds the login name and password to a web account.
