Hackers stole personal data from 29 million Facebook users in a recent hack, including information like phone numbers, emails, gender, hometowns and even relationship data.
Was your data stolen? (Mine was.) There’s an easy way to check. Visit this Help Center page on Facebook’s website and log in to your account. It will tell you whether or not your data was stolen, and which data in particular.
Here’s what it looks like when the hackers took a lot of data.
Worth noting, while Facebook’s alert says that no “payment card or credit card information” was stolen, Facebook product executive Guy Rosen did say that hackers would have been able to see the last four digits of a user’s credit card through this hack.
Facebook also says it will reach out to people directly if their data was stolen.
“In the coming days, we’ll send customized messages to the 30 million people affected to explain what information the attackers might have accessed, as well as steps they can take to help protect themselves, including from suspicious emails, text messages, or calls,” Facebook wrote in a blog post.
