The breach was first reported in September after one of the hackers advertised the stolen data on an English web forum. The hacker offered to sell access to people's account for 10 cents each. According to the reports, the user named FBsaler claimed their database includes 120 million accounts, but the number was not confirmed by the cybersecurity experts.
