Change passwords and user names?
Many news reports are quoting secruity gurus who recommendi that anyone using the Web immediately change their user names and passwords, particularly on ecommerce and financial sites. Is that overkill or an appropriate response?

Tip of the iceberg IMHO
Heartbleed is, without question, an "earthshattering" bug.  However, it strikes me that there's still another shoe to drop.  What I mean by that is that OpenSSL is open source, right?  Tons of other developers use it: they link against it, copy/paste it, set up web services to incorporate it, etc.  

Remember the ASN1 parsing vulnerability from a few years back (http://www.securityfocus.com/bid/8732)?  Take a look at the list of products impacted and you'll see what I mean (the list goes on for page after page).  Why were so many products impacted?  Becuase that source was reused - and reused - and reused again.  We were literally dealing with that bug for a decade after the fact because that code was used in everything from embedded devices to medical equipment to ICS systems. 

So what really concerns me is less the population of web servers that this impacts - because, impactful as that is, they can at least upgrade fairly easily.  What really makes me nervous is what else is vulnerable that can't be upgraded quite so easily.  This code is in a lot of stuff, in particular embedded systems.  Mark my words -- we'll be deling with this one for a while.

OpenSSL TLS DTLS Heartbeat Extension
How important are the Antivirus Vendors in releasing the singatures for this vulnerablility as they use the webservers like apache?

Re: On the backend
I fully agree - now we are in the era of risk and uncertainty. Somehow as the normal people, we have to ignore something on purpose. If I think over about how many people/agencies have found my personal data during various exploration, I feel really deterred and cannot sleep well.:-(

Re: On the backend
Official voices referes to an implementation mistake ... but Snowden's revelations have sown the seeds of distrust. This is just the beginning.  The only certainty is that the flaw is very disconcerting ... and probably many Intelligence agencies have exploited it in the past.

Re: On the backend
That's a great question, @Ryan Sepe. I know it was an implementation flaw in OpenSSL. It would be interesting to know what exactly introduced the problem in that version 2 years ago.

On the backend
This is very scary that this exploit has come to light. Especially since it is very difficult and will be extensive to make sure that this exploit is remediated based on some of the safeguards mentioned in the article. If you can spoof the server and step in as if you were that server from a malicious standpoint there is no end to the data that will be compromised. Also, does anyone know how this vulnerability came to be? Meaning I am sure there are many ways that a site can be checked for activity, what is it about the previous creation of the heartbeat extension that provided this hole?
