Security researcher Graham Cluley notes a popular hoax circulating on Facebook. Just like email hoaxes, when the message asks you to share this warning with all your friends, it is usually a hoax.
QUOTE: More and more Facebook users have been sharing a message warning of a change in Facebook’s privacy settings, and how a new “Graphic app” could let any member of the social network see your photos, likes and comments. Despite the message being inaccurate, and containing a number of misunderstandings, it continues to circulate. The truth is that there is no such thing as “Graphic App”, and the material you post on Facebook is viewable by others based upon the sharing settings you have chosen, just as it has always been.
COPY OF HOAX MESSAGE: Hello to all of you who are on my list of contacts of Facebook. I would like to ask a favour of you…. You may not know that Facebook has changed its privacy configuration once again. Thanks to the new “Graphic app”, any person in Facebook anywhere in the world can see our photos, our “likes” and our “comments”. During the next two weeks, I am going to keep this message posted and I ask you to do the following and comment “DONE”. Those of my friends who do not maintain my information in private will be eliminated from my list of friends, because I want the information I share with you, my friends, to remain among my friends and not be available to the whole world. I want to be able to publish photos of my friends and family without strangers being able to see them which is what happens now when you choose “like” or “comment”.
Unfortunately we cannot change this configuration because Facebook has made it like this. So, please, place your cursor over my photo that appears in this box (without clicking) and a window will open. Now move the cursor to the word “Friends”, again without clicking and then click on “Settings”. Uncheck “Life Events” and “Comments and Like”. This way my activity with my family and friends will no longer be made public. Now, copy and paste this text on your own wall (do not “share” it!). Once I see it published on your page, I will un-check the same for you. Thanks so much.
