Mumsnet Privacy Snafu Exposes User Info

Mumsnet has suffered a serious data leak affecting potentially thousands of users after a software glitch during an IT system migration to the cloud. Justine Roberts, founder and CEO of the popular parenting forum, explained in a blog post late last week that the issue affected users for the best part of two days: from 2pm on February 5 to 9am on February 7. “During this time, it appears that a user logging into their account at the same time as another user logged in, could have had their account info switched,” she said. “We believe that a software change, as part of moving our services to the cloud, that was put in place on Tuesday pm was the cause of this issue. We reversed that change this morning. Since then there have been no further incidents.” The site admins also forced users to log-in again, ensuring they would be locked out of any accounts not their own.
