Twitter has not responded to the hack since the first reports on December 24. The company, which has been owned by billionaire Elon Musk since late October, has since been repeatedly asked about it. It is therefore not clear whether and what steps Twitter has taken to investigate the hack and to close the leak.
The hack may have taken place as early as 2021. It is unknown who carried out the hack.
A major hack at Twitter could arouse the suspicion of regulators in Europe and the United States. They are already alert because Twitter under Musk may not have complied with European data protection rules and agreements with the American watchdog.
