Startling new revelations from Twitter's former head of security, Peiter Zatko, have raised serious new questions about the security of the platform's service, its ability to identify and remove fake accounts, and the truthfulness of its statements to users, shareholders and federal regulators.
Zatko — better known by his hacker handle “Mudge” — is a respected cybersecurity expert who first gained prominence in the 1990s and later worked in senior positions at the Pentagon’s Defense Advanced Research Agency and Google. Twitter fired him from the security job early this year for what the company called “ineffective leadership and poor performance.” Zatko's attorneys say that claim is false.
