UPDATED: By now, you should have heard about the Heartbleed bug that decimated encryption for web servers that were using a version of OpenSSL dated December 31, 2011 or later.
What to do?
Change your passwords on accounts where you would be upset if someone were to steal into a digital trove of personal information — like credit card numbers, for example.
Generally speaking, if you change your passwords before a site implements a patch, you’ll need to change it again afterwards. Tumblr, for example, advised its members to change passwords after it installed the patch. Ditto LastPass, which explained its encryption scheme, one that includes something called perfect forward secrecy.
Check to see if the site has already taken the first step towards correction. And be prepared to change those passwords again after web site admins have completed all steps necessary to plug the hole.
If you use Chrome, install the Chromebleed checker, which “[d]isplays a warning if the site you are browsing is affected by the Heartbleed bug.” But no major site should still have flawed SSL software on Wednesday.
Who’s affected and who’s done what?
According to Netcraft, which monitors the web technology, more than a half million sites are currently vulnerable.
I’ve not found a central location that catalogs which sites have publicly announced their status. So I’m going to link to announcements in a list here.
Prominent sites that were vulnerable
- Amazon : AWS was affected but Amazon says that it was not; this does not compute
- Buffer : on AWS, has rekeyed certificates
- Canada Revenue Agency : halted online tools
- Delicious : recommended updating password
- Facebook : “added protections” before public announcement – use two-factor authentication or change your password
- Four Seasons Hotel
- Google (Blogger/Blogspot, gMail, YouTube) : “We fixed this bug early and Google users do not need to change their passwords.”
- Instagram (owned by FB – change your password)
- Last Pass
- Minecraft : advised customers to change passwords
- Pinterest : emailed accounts only if Pinterest thought they may have been affected
- Pocket : advised customers to change passwords
- SoundCloud : logged everyone out, recommended password update
- Tumblr : advised customers to change passwords
- Yahoo (Yahoo Homepage, Yahoo Search, Yahoo Mail, Yahoo Finance, Yahoo Sports, Yahoo Food, Yahoo Tech, Flickr, and Tumblr)
Sites that appear to have been free of the vulnerability
- Apple : was not running affected software
- Bank of America
- Capital One
- eBay : was not running affected software
- Microsoft (Bing, Hotmail, Live.com) : was not running affected software
- Slideshare (owned by LinkedIn)
- Wells Fargo
Web encryption 101
Netscape introduced SSL (secure socket layer) encryption in 1994. Websites that are sharing information securely show that in two ways: the protocol is https instead of http, and you’ll see a lock alongside the URL in the browser.
On an encrypted site, if someone is “listening in” to the transaction between your computer and the web server, they’ll hear (read) only noise, not plain talk (text).
Today OpenSSL is the dominant form of web encryption, and no one knows how many sites are at risk. However, Apache and nginx run about two-thirds of the sites on the web; both use OpenSSL. “The code library is also used to protect email servers, chat servers, virtual private networks and other networking appliances,” according to PC World. Note: not all passwords are encrypted with SSL.
