What Is Heartbleed and Why Is It So Dangerous?
In your typical security breach, a single company’s user records/passwords are exposed. That’s awful when it happens, but it’s an isolated affair. Company X has a security breach, they issue a warning to their users, and the people like us remind everyone it’s time to start practicing good security hygiene and update their passwords. Those, unfortunately, typical breaches are bad enough as it is. The Heartbleed Bug is something much, much, worse.
The Heartbleed Bug undermines the very encryption scheme that protects us while we email, bank, and otherwise interact with websites we believe to be secure.

The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).
The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.
That sounds pretty bad, yes? It sounds even worse when you realize roughly two-thirds of all websites using SSL are using this vulnerable version of OpenSSL. We’re not talking small time sites like hot rod forums or collectible card game swap sites, we’re talking banks, credit card companies, major e-retailers and e-mail providers. Worse yet, this vulnerability has been in the wild for around two years. That’s two years someone with the appropriate knowledge and skills could have been tapping into the login credentials and private communications of a service you use (and, according to the testing conducted by Codenomicon, doing it without a trace).
Although no group has come forward to flaunt all the credentials and information they siphoned up with the exploit, at this point in the game you have to assume that the login credentials for the web sites you frequent have been compromised.
What to Do Post Heartbleed Bug
Any majority security breach (and this certainly qualifies on a grand scale) requires you to assess your password management practices. Given the wide reach of the Heartbleed Bug this is a perfect opportunity to review an already smooth-running password management system or, if you’ve been dragging your feet, to set one up.
Before you dive into immediately changing your passwords, be aware that the vulnerability is only patched if the company has upgraded to the new version of OpenSSL. The story broke on Monday, and if you rushed out to immediately change your passwords on every site, most of them would still have been running the vulnerable version of OpenSSL.
It looks like this weekend is shaping up to be a good weekend to get serious about updating your passwords. First, you need a password management system.
You need to start changing your passwords. is a great way to ensure you don’t miss any passwords; Here it highlights the basics of good password hygiene, quoted here:

Passwords should always be longer than the minimum the service allows for.
If the service in question allows for 6-20 character passwords go for the longest password you can remember.
Do not use dictionary words as part of your password.
Your password should never be so simple that a cursory scan with a dictionary file would reveal it. Never include your name, part of the login or email, or other easily identifiable items like your company name or street name. Also avoid using common keyboard combinations like “qwerty” or “asdf” as part of your password.
Use passphrases instead of passwords.
If you’re not using a password manager to remember really random passwords (yes, we realize we’re really harping on the idea of using a password manager) then you can remember stronger passwords by turning them into passphrases. For your Amazon account, for example, you could create the easily remember passphrase “I love to read books” and then crunch that into a password like “!luv2ReadBkz”. It’s easy to remember and it’s fairly strong.
Security vulnerabilities, especially ones with such far reaching implications, are never fun but they do offer an opportunity for us to tighten our password practices and ensure that unique and strong passwords keep the damage, when it occurs, contained.
