If you haven't heard about the heartbleed bug and related security issues, this article provides a good explanation.
Applications developed in FPHC and deployed using the FP Application servers are not vulnerable to this bug.
Services we use from Amazon and GitHub were affected. SSL connections to our servers go through Amazon software, and we use SSL to connect to GitHub repositories. Both Amazon and GitHub have already updated their services to remove the vulnerability. FP Complete has followed GitHub's suggestions by changing our passwords and OAuth tokens. You can read those guidelines at github.
While we have no evidence that any sensitive information was leaked from FPHC, we recommend changing your password for FPHC as soon as possible, just in case.
Other measures to increase security never hurt. Things like using two-factor authentication on sites for which it is available, and using password locker software that will generate strong passwords unique to each site, will help prevent people breaking into your accounts. This event provides a good time to consider adding these extra security measures if you aren't already using them.
