A hacker attack hit Twitter after an unknown individual managed to steal the records (emails and phone numbers) of approximately 5.4 million Twitter users. The issue with Twitter’s cyber security was reported via a bug bounty portal in January 2022, but Twitter failed to address it promptly. No passwords were included in the breach, but the hacker has managed to sell the stolen data to at least two buyers, which means that people included in the list may soon be targeted by cybercriminals.
