Facebook does not plan to notify half-billion users affected by data leak

Facebook Inc did not notify the more than 530 million users whose details were obtained through the misuse of a feature before 2019 and recently made public in a database, and does not currently have plans to do so, a company spokesman said on Wednesday.

Business Insider reported last week that phone numbers and other details from user profiles were available in a public database. Facebook said in a blog post on Tuesday that "malicious actors" had obtained the data prior to September 2019 by "scraping" profiles using a vulnerability in the platform's tool for synching contacts. The Facebook spokesman said the social media company was not confident it had full visibility on which users would need to be notified. He said it also took into account that users could not fix the issue and that the data was publicly available in deciding not to notify users. Facebook has said it plugged the hole after identifying the problem at the time.
