A whistleblower claimed that Twitter had “egregious deficiencies” in data privacy and other sensitive areas, and had misled regulators over its cyber defences. Peiter Zatko was head of security at Twitter from late 2020 until his sacking earlier this year. The company said his allegations were full of “inconsistencies”. Mr Zatko’s claims about the handling of fake accounts parallel Elon Musk’s reasons for wanting to ditch his takeover of Twitter. Mr Musk’s lawyer said a subpoena had been issued to Mr Zatko. A subpoena has also been handed to Jack Dorsey, Twitter’s former boss, ahead of a trial that will determine if the deal should go ahead.
