The 2018 Google data breach was a major data privacy scandal in which the Google+ API exposed the private data of over five hundred thousand users.[1]
Google+ managers first noticed harvesting of personal data in March 2018,[2] during a review following the Facebook–Cambridge Analytica data scandal. The bug, despite having been fixed immediately, exposed the private data of approximately 500,000 Google+ users to the public.[3] Google did not reveal the leak to the network's users.[4] In November 2018, another data breach occurred following an update to the Google+ API. Although Google found no evidence of failure, approximately 52.5 million personal profiles were potentially exposed.[5] In August 2019, Google declared a shutdown of Google+ due to low use and technological challenges.[6][7][8]
