Whistleblower expected to give damning evidence of data and information security failings

Twitter's former head of security, Peiter Mudge" Zatko, will appear in front of lawmakers in Washington on Tuesday. He is expected to give damning evidence of data and information security failings at the social media platform, having outlined a litany of concerns in a whistleblower complaint last month.

The former hacker, widely respected in his field as an information security specialist, joined Twitter on 16 November 2020 and was fired on 19 January 2022. His complaint levels allegations of incompetence and fraud at Twitter, saying that he uncovered extreme, egregious deficiencies by Twitter in every area of his mandate", including weak controls of employee access to user data and interference by foreign governments.
