Facebook Security Bug Exposed

Facebook Security Bug Exposed
Security and Privacy on Internet is a real issue now in more complex social media world. With more and more people having social website accounts their privacy and information is at risk.

Recently a new Facebook security bug is exposed that exposes users’ personal contact information like emails or/and phone numbers to other users who were connected to them on facebook.

Currently this bug is affecting more than 6 million accounts on facebook.com

The security team at Facebook wrote in a blog post published today that when people upload their contact lists or address books to Facebook, we try to match that data with the contact information of other people on Facebook in order to generate friend recommendations.

This may be is a reason for the exposed security bug in the contact and recommendation system on Facebook.

On the official security blog security team reported:
“Because of the bug, some of the information used to make friend recommendations and reduce the number of invitations we send was inadvertently stored in association with people’s contact information as part of their account on Facebook,” the post continued. “As a result, if a person went to download an archive of their Facebook account through our Download Your Information (DYI) tool, they may have been provided with additional email addresses or telephone numbers for their contacts or people with whom they have some connection.”
It is believed that this bug is active for quite some time now and it was discovered by the security team last week. Facebook security team fixed the bug less than 24 hours after it was brought to their attention.

“For almost all of the email addresses or telephone numbers impacted, each individual email address or telephone number was only included in a download once or twice,” the post on the security blog on facebook reported. 

“This means, in almost all cases, an email address or telephone number was only exposed to one person. Additionally, no other types of personal or financial information were included and only people on Facebook – not developers or advertisers – have access to the DYI tool.”
