It's hard to disseminate all the info running rampant across the internet regarding the Heartbleed SSL vulnerability which has been the big media talk over the past week and a half. We mostly stayed away from the story to avoid spreading any "fear-mongering."
Still, that doesn't mean we don't want to offer some useful intel for you guys. We've been holding out so we could wait until much of the initial hype died down and something useful came along. The above infographic is precisely that. The cybersecurity experts at LWG Consulting have put together a handy infographic which gives details on which major websites/web-services we should change our passwords on ASAP. It also shows some websites that we can breathe easier about.
It's possible that this infographic isn't 100% exhaustive, but it should be a great starting reference. Many of the companies who own these websites are currently scrambling to fix the vulnerability. Some of them have already fixed the vulnerability, but the problem has been there for years, so it is best to change your password regardless.
