NEW YORK (AP) - Security experts are warning all Internet users to change all of their passwords because of a threat called Heartbleed that breached encryption technology used to securely transmit email, e-commerce transactions, social networking posts and other Web traffic. The threat is considered serious because it has remained undiscovered for more two years. The breach involves SSL/TLS, an encryption technology marked by the small, closed padlock and "https:" on Web browsers to signify that traffic is secure.
