The Facebook Friend Suggestions security scare

Warnings are being posted all across Facebook suggesting that users who have received multiple friend suggestions are really infected with a computer virus.

 

A typical version of the warning reads as follows:

VIRUS WARNING: ANYONE WHO HAS GOTTEN A TON OF FRIEND SUGGESTIONS BE CAREFUL! IT IS A VIRUS! IF YOU ACCEPT THEM THEN YOUR ACCOUNT WILL SEND OUT ABOUT 85 TO SOMEONE ELSE!!! WARN YOUR FRIENDS NOW! This is a new virus that is sending requests to spread. DO NOT ACCEPT FRIEND SUGGESTIONS AT THE MOMENT!

The reality, however, is somewhat different. Most importantly, the behaviour and sightings of more than the usual number of Friend Suggestions are not a sign of a computer virus infection.

 

Instead, it appears that Friend Suggestions on Facebook now go to both parties, rather than just the one you specifically suggests takes up your suggestion of a new online connection.

 

So, imagine you are Tom, and you think that your friend Dick should become Facebook friends with Harry. You visit Dick’s Facebook profile, scroll down to where it says “Suggest friends for Dick” and choose Harry’s name.

Your suggestion that Dick should become friends with Harry doesn’t just go to Dick, but it will also now go to Harry as well. Presumably Facebook has made this change in order to encourage more users to interconnect.

 

But there’s more.

 

As Facebook reveals on its help pages about Friend Suggestions, Facebook can alsosuggest possible friends for you to connect with.

 

It does this by automatically examining “the networks that you are a part of, mutual friends, work and education information, contacts imported using the Friend Finder, and many other factors.”

 

Aside from the mysteriously ambiguous “many other factors”, the thing I find concerning there is the reference to Friend Finder.

 

What Facebook means is that they can suggest friends based upon email addresses that you may have imported into Facebook from your email account address book, perhaps when you first set up your account.

 

What many people may not realise is that even if you didn’t add everyone you imported from your address book as a Facebook friend, Facebook can still use those contacts imported from Outlook, Gmail, Hotmail, Yahoo, etc, in order to make future recommendations.

 

Therefore, Facebook may also see your email address in other people’s contact lists, and determine relationships based upon that.

 

If this bothers you (and I can perfectly understand why it would), then Facebook says you can tell it to remove the contacts from its suggestions system. Of course, it might have been better if you hadn’t offered up your address book to Facebook in the first place..

 

Facebook also says that you can change your privacy settings to prevent your profile from being visible to everyone as a potential friend suggestion.

 

More information about Facebook’s Friend Suggestions system can be read online here.

 

No doubt most of the souls forwarding and reposting this latest Facebook security scare to their profiles are oblivious to all these fine details, however, and are still believing that a virus is behind the suggestion messages that they are viewing.

 

Of course, it should still go without saying, that whether you receive a friend request or a friend suggestion, you should exercise caution about who you befriend on a social network – as it could be a cybercriminal rather than a long lost chum who is trying to access your profile.

Facebook disables chat after security hole discovered

Facebook has taken down its instant messaging-style system which allows members to chat real-time with each other after claims that the system suffers from a serious security problem.

 

According to a report by TechCrunch, a security flaw allows your Facebook friends to secretly spy on your private live chats as well as any see any pending friend requests that you have made.

 

In the past Facebook has insisted that privacy is its “highest priority”, but there isgrowing concern that the site has played fast and loose with the personal information of its 400 million users, encouraging them to share too much private data online and changing privacy settings to be more “open”.

 

A video has been posted on YouTube which allegedly demonstrates the security hole:

 

The news that Facebook has disabled its chat system suggests that they are working on fixing the security problem. Hopefully it will be resolved quickly.

 

But even if this security issue is fixed promptly there are other security issues on Facebook, as with any other social network, that need to be considered if you plan on continuing to use the site. Make sure you read our guidelines for better security and privacy on Facebook.

The Hacker Door Facebook security scare

A warning being sent across Facebook is scaring users into believing that their accounts have been hacked.

 

Here is a typical example of a warning message:

To all of my friends: COPY & PASTE: New problem found.... Hacker in door in our friends list!....We are now listed as friends of ourselves! You need to delete yourself from your friends list to close the door to hackers. To do this ... Go to Account, go to edit friends, there search for your name on the list and click the X to get your name removed.

 

The problem with this warning is that it’s complete poppycock, and causing some users to panic that they could have been hacked.

 

Yes, there is a bug that means that when you search through your Facebook friends list, you show up yourself as one of your friends. And yes, even if you try and “delete” yourself as a friend you’ll pop up again when you refresh the webpage.

 

But this is not evidence that your account has been compromised, and if you forward this warning to your Facebook friends and acquaintances you are only helping to perpetuate the hoax.

 

We saw a similar hoax spreading across Facebook earlier this year in what we called the “Automation Labs” security scare.

 

In summary, the “Hacker Door” scare is not something to worry about, and you should always check your facts before forwarding security warnings like this to your friends and colleagues.

 

However, there are real security issues on Facebook, as with any other social network. Make sure you read our guidelines for better security and privacy on Facebook.

 

Oh, and you might want to become a Fan of Sophos on Facebook too!

Facebook privacy settings: What you need to know

Facebook is making big changes to its privacy settings that may mean millions of people begin to expose information that they previously considered to be restricted to only their Facebook friends to the entire internet.

This YouTube video explains more.

 

Facebook is recommending that users adopt a series of new privacy settings that would reveal their personal data to anyone on the internet. Chances are that when you login to Facebook today you’ll be advised to make various pieces of your personal information available for “Everyone” to see.

To get a clear picture of what Facebook means by everyone (and its implications) you should check out the revised Facebook privacy policy:

 

"Information set to 'everyone' is publicly available information, may be accessed by everyone on the Internet (including people not logged into Facebook), is subject to indexing by third party search engines, may be associated with you outside of Facebook (such as when you visit other sites on the internet), and may be imported and exported by us and others without privacy limitations."

"The default privacy setting for certain types of information you post on Facebook is set to 'everyone.' You can review and change the default settings in your privacy settings. If you delete 'everyone' content that you posted on Facebook, we will remove it from your Facebook profile, but have no control over its use outside of Facebook."

 

So, let’s make this clear. If you make your information available to “everyone”, it actually means “everyone, forever”. Because even if you change your mind, it’s too late – and although Facebook say they will remove it from your profile they will have no control about how it is used outside of Facebook.

 

There’s a real danger that people will go along with Facebook’s recommendations without considering carefully the possible consequences.
