More than 200,000 people in Delaware may have had their personal data exposed as part of the recently disclosed Facebook data breach, according to data released from Facebook to the Delaware Department of Justice.

The estimate of the possible extent of the data breach in Delaware came from responses by Facebook to questions posed by Attorney General Matt Denn’s office and other state attorneys general who are conducting investigations of the breach of personal privacy involving Facebook information. Global Science Research may have improperly shared Facebook information of up to 87 million users worldwide with Cambridge Analytica and other third parties, according to the company’s public disclosures.

In Delaware, Facebook estimated 902 users installed the app through which Global Science Research gained access to personal information of those users and of those users friends. Facebook estimated that up to 200,651 users in Delaware were friends with people on Facebook who had installed the app.

Facebook’s estimates provided to the attorneys general showed that approximately 196,000 Facebook users in the U.S. downloaded the app, but more than 46 million Facebook users in America were friends with someone who had downloaded the app, thus were potentially exposed.

While some people have chosen to delete their Facebook account, there are other steps that can be taken to reduce information shared through third-party apps. Experts say users should minimize the number of apps that they have installed — users can go to Settings and click on “Apps and Settings” to see the apps they have installed and click to delete any of them. Outside of Facebook, it is also recommended that people not use the option for many websites or apps offer to log in with their Facebook account because that login allows data sharing between Facebook and the website or app.
