Heartbleed reveals Internet insecurity: everything you need to know



So does this mean that TurboTax was vulnerable to heartbleed, but now it is no longer vulnerable because it is secured, so users should change their passwords? Or does this mean TurboTax was never vulnerable to heartbleed, so no need to change passwords?


I've seen some chatter already about how this was the net effect of poor programming from an amateur open source development team. The quality of the programming (and arguably the review process) and the open source nature of the library are two completely different aspects that should not be conflated, however. A proprietary SSL library developed behind closed doors could have easily introduced the same flaws. The open source nature of the library may have made it easier for attackers to craft exploits against the heartbeat feature, but it's likely that a similar feature+flaw in a proprietary library would have been compromised the same way. The internet's most skilled and nefarious are never slowed down much by working with compiled binaries as opposed to source, and security through obscurity is widely stigmatized for good reason.




Heartbleed reveals Internet insecurity, but what should you do




Unfortunately, you can't without having a copy of the old certificate to check against the revocation list. In my findings, it was actually extremely difficult, and usually impossible to get this exploit to disclose any key material unless exactly the right circumstances existed. More than anything, what was at risk is the encrypted data that was being sent to and received from servers.Over the last two years, it's somewhat unlikely that this was actively being exploited, but just about anything you've done in the last 3 days anywhere on the internet should be considered entirely compromised. If you've had any active sessions on any sites, you should logout (someone can 'assume' your session to get into your account), and change any passwords you may have used in the last week. This includes major sites such as Facebook, GitHub, Indiegogo, etc, although I know most large organizations are aware of this threat, and have manually reset all active sessions in order to mitigate it. 2ff7e9595c
