The latest Unseen Podcast takes to the air. Hosted by +Adam Synergy, and with military veterans +Antonio Paris and +Kenneth Wisian joining +Sam Lichtenstein on the panel, we hear many good stories about what it's like to fly (and jump) into danger.

Episode 68 is out. If +Adam Synergy or the panel want to add any linkage to the show notes, just let me know.

The music by DJ Spooky you hear on every episode is Creative Commons and you can get the whole album here:

+Adam Synergy I lurked for most of it. A very good episode. I think I have the whole thing captured, but please don't delete the video until I have it out in audio. Thanks +Kenneth Wisian, +Antonio Paris, & +Sam Lichtenstein for being a fine panel. The subject matter was not the sort of thing we usually cover, but that's healthy.

Ouch.

This is about as bad as it gets. CloudFlare is a service that sits between a website and the website’s users that makes it easier for the website to serve its data to users around the globe. A vast number of websites use CloudFlare. One internet technology company reports, “CloudFlare is used by 71.8% of all the websites whose reverse proxy service we know” (https://w3techs.com/technologies/details/cn-cloudflare/all/all). Because of how CloudFlare works, even on websites that use encrypted connections (HTTPS), the websites’ data flows through CloudFlare unencrypted before being sent to the user.

It turns out a flaw in CloudFlare’s systems caused unencrypted data from one website to be served up along with the data from another website on accident.

It used to be that the worst case scenario for internet security was if a flaw in a website allowed any unauthorized person to access secret information on that website. Something much worse has happened. Someone browsing Uber.com might inadvertently be sent a little data, a private message perhaps, meant for an OKCupid.com user.

But it’s much worse than just that. Search engines like Google and Bing crawl the web, downloading websites and storing them in massive caches to be indexed and searched. So let’s say Google’s web crawler is the “person” who accessed uber.com and was sent that private message from OKCupid.com. Now that private information is searchable on Google. In other words, CloudFlare has for months been spraying unencrypted private information like a firehose all across the internet—private messages from major dating sites, full messages from a well-known chat service, online password manager data, frames from adult video sites, hotel bookings, passwords, keys… A quick search of an incomplete list of affected websites turns up 3,662 sites with “bank” in the name. Search engines are still working to purge their caches of this data.

Regardless of who you are, you need to change your passwords. Now is a great time to adopt a password manager like 1Password. Since you will be changing your passwords anyway, adopting 1Password isn’t any extra work. Ironically, 1Password.com uses CloudFlare, but 1Password designed their security system specifically to protect against unforeseen scenarios like this, so 1Password was not affected by the security breach.

Shouting about 'Earth 2.0' really undermines the true excitement of the TRAPPIST-1 system -- and that is, the planets may have a completely different formation history to our own.
