Facebook says hundreds of millions of passwords were exposed internally
"This caught our attention because our login systems are designed to mask passwords using techniques that make them unreadable.
"We have fixed these issues and as a precaution we will be notifying everyone whose passwords we have found were stored in this way.
"To be clear, these passwords were never visible to anyone outside of Facebook and we have found no evidence to date that anyone internally abused or improperly accessed them.
"We estimate that we will notify hundreds of millions of Facebook Lite users, tens of millions of other Facebook users, and tens of thousands of Instagram users.
"Facebook Lite is a version of Facebook predominantly used by people in regions with lower connectivity." ■
