Facebook is warning 1 million users about stolen usernames, passwords

Meta Platforms Inc. said it would notify roughly 1 million Facebook users that their account credentials may have been compromised due to security issues with apps downloaded from Apple Inc. and Alphabet Inc.’s software stores.

The company announced Friday that it identified more than 400 malicious Android and iOS apps this year that target internet users in order to steal their login information. Meta said it informed both Apple and Google about the issue in order to facilitate removal of the apps.

The apps worked by disguising themselves as photo editors, mobile games or health trackers, Facebook said.
