Dear Mom, Dad, Gramma, Brothers, Aunts and Uncles
I've got some bad news. You may have some work to do to keep your private information safe and prevent people from being able to impersonate you on the Internet.
As you know, I'm a computer programmer. Or a nerd. Or whatever. Essentially people give me money to sit on my butt and get fatter. Yes Mom, I know I haven't called in a few weeks. I'm sorry. Anyway, my people have really let you all down right now.
You see, there's a problem with the Internet right now. It's even worse because Facebook, Twitter, and Google are central to our digital lives.
You know how when you sign in to Yelp on your phone it asks you to log in with Facebook? Or how more and more web pages ask you to Log in with Google? Well, that's gotten a bit more dangerous in the last month.
Essentially there is a security problem in a very common framework, called Ruby on Rails. This framework runs a lot of websites. Websites like Meetup.com, tons of facebook games, and quite a few business applications like Harvest
If an app you added on Facebook, Twitter, Google or LinkedIn is compromised it gives the attacker the ability to do whatever that app is allowed to do on facebook, twitter, google or linked in.
Even worse many of the applications we developers make are greedy about what we want you to allow the app to do. Some social games require you to give them the right to post things on your friends timeline before they'll even let you play! What dirtbags, right?
I figured I should apologize for all of us, as well as inform you of the risks that you are now being exposed to, as well as what steps to take to make yourself a little safer.
Protecting Your Google Accounts
Google is the largest concern for me. I use it to log in to all kinds of things and it has tons of my personal data in it. Including client lists, budgets, and things like that.
Apps you log in to with Google can access all kinds of things; like your contacts, email, calendar, documents in google drive, and even your chat history if you use google chat!
Thankfully it's pretty straightforward to revoke access with Google, though a bit time consuming. They have a support page explaining how, located here: http://support.google.com/accounts/bin/answer.py?hl=en&answer=41236
Protecting Your Facebook Account
Most Facebook apps are allowed to get your contact information, many can post status or pictures, and a few can add or remove friends.
If your not cool that some stranger on the Internet can someday possibly impersonate you on Facebook, even if you change your password you may want to follow these instructions.
I know, I know. It's painful. You have to click twice per app you want to remove, and if you're like me you somehow have accumulated dozens of them over the years. Oops. I'll think twice before logging in with facebook!
Protecting Your Linked In Account
Most LinkedIn apps can access your personal information, as well as post updates to your timeline. Some can update your work history, or send private messages.
It's easy to revoke access on LinkedIn, especially because there are so few apps for the platform!
Protecting Your Twitter Account
Most twitter apps can update your status, some can send DMs. A lot of my personal brand is tied up in Twitter, so this is more important for me than LinkedIn, but I'm assuming the opposite is true for you.
Revoking twitter access is a joy compared to Facebook!
The Thrilling Conclusion
I would strongly recommend removing all access for Facebook, Twitter, Google, and LinkedIn apps for the time being. If you really need whatever app it was, contact the apps support team and ask them if they are using rails, and if so if they are up to date with the latest security patches. If they say yes, then you're good to go!
I wish I could say this was all you should be worried about, but we're in for a bumpy ride over the next few months.
