How Did the Breach Occur?
The Duolingo breach was possible because of a vulnerable API or application programming interface. The API was designed to enable programmers to connect their services to Duolingo, but a small issue with it enabled attackers to harvest huge amounts of information from Duolingo, getting access to information that shouldn't have been available to the public.
When Did This Breach Occur?
The API issue has been known since March of 2023. That means the breach could have occurred in and around March or the months after.
Who Does the Breach Impact?
Over 2.6 million Duolingo users were exposed by this breach. It's the users that are at risk because of the information shared. Even though the data stolen wasn't substantial for each person, it could still be used to launch phishing attacks and steal customer data.
