A bug in Facebook’s “Download Your Information” tool caused some six million users’ contact information being shared with other members. Facebook said on Friday that it had discovered and patched this bug, but the six million users were notified that their phone numbers or e-mails had been exposed. Facebook said that this incident is something that they’re “upset and embarrassed by” and that they will make sure “nothing like this happens again.”
The social network further says that to its knowledge, there have been no reports of this bug being exploited for any sort of wrongdoing, and that it has received no complaints from the affected users. Facebook will be sending a detailed email to these six million users, telling them about the number of people with which their contact information was mistakenly shared due to the bug. Facebook has published a detailed post regarding this bug on its security blog, basically if someone downloaded their information through the DYI tool, their archive may have included contact details for someone they were connected with but didn’t necessarily had the details for. According to Facebook this bug was fixed within 24 hours.
