Facebook has admitted that a software bug in the social network has inadvertently exposed contact details of around 6 million users. Apparently the bug led to the exposure of user email addresses or phone numbers to other users. However, Facebook says that no financial or other personal information was revealed to others and there were no signs of any malicious exploitation of the bug. The company said it is likely that only known acquaintances would have had access to the information.
The social network in a blog post said the bug manly caused a problem with Download Your Information (DYI) tool.
Facebook said "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. Because of the bug, the email addresses and phone numbers used to make friend recommendations and reduce the number of invitations we send were inadvertently stored in their account on Facebook, along with their uploaded contacts."
"As a result, if a person went to download an archive of their Facebook account through our Download Your Information (DYI) tool, which included their uploaded contacts, they may have been provided with additional email addresses or telephone numbers"." The social network added.
Anyways Facebook has said that the problem has been fixed and the affected users have been notified via Email. The Social Network made an apology in the blog post saying "We recognize that mistakenly sharing contact info is unacceptable, even if you are acquainted with people who saw these details, and we've taken measures to prevent this from happening again"
"All of us at Facebook take this issue very personally. We appreciate your ongoing use of Facebook, and are working every day to deliver the level of service you expect and deserve." it added.
