Facebook data leak ZDnet was among those who reported the huge incident, and they noted that the whole argument that the data came from 2019 was not strong enough since not a lot of people change their numbers. Security firm Hudson Rock's CEO Alon Gal tweeted regarding the incident in January saying the database "came to the fore" especially when a Telegram user had made a bot that would allow users to query the whole database for a simple fee.
