Yesterday, Community Health Systems announced that Chinese hackers had managed to steal the healthcare records of 4.5 million of its customers. Now, security firm TrustedSec is claiming that the reason the information was swiped was because of the world-famous Heartbleed vulnerability. TrustedSec founder David Kennedy then told Bloomberg that he learned this fact from three unnamed insiders who told him under the cloak of anonymity. The security expert went on to say that the attack took place roughly a week after Heartbleed was made public, but before the healthcare chain could patch the hole in its system. We don't think we need to tell you what the lesson is, here.
