The Heartbleed bug was found in some of the latest versions of the OpenSSL open source cryptography library used by millions of websites globally. Many websites use OpenSSL when implementing secure connections over HTTPS (signalled by a padlock symbol in the browser). This widspread bug means that a hacker could potentially exploit a coding error in OpenSSL to extract usernames and passwords from secure websites.
I have received an email letter from my web hosting company advising that the servers hosting Adam Dimech Online have been patched and rigourously tested against this bug. Additionally, since no services on my website use SSL encryption, users of this website should remain unaffected.
