A bug named "Heartbleed" was recently discovered and likely affects most websites on the Internet. Fortunately, an online tool makes it easy for users to quickly check whether a website is secure or not.
Heartbleed is a bug that affects OpenSSL, a technology that is used by many Internet services to keep user data secure. Hackers can take advantage of the bug to steal a key code that can then be used to steal information, including user passwords.
A fix has been created for the bug, but many websites across the Internet have still not implemented it to their services.
