Twitter has terminated Peiter Zatko, head of security, and Rinki Sethi, chief information security officer, from its top security team, The New York Times reported.
Peiter Zatko, head of security, populary known as Mudge, is no longer at the company. Rinki Sethi, chief information security officer, will depart in the coming weeks.
Twitter CEO Parag Agrawal, in a memo to its employees, wrote that the moves follow an assessment of how the organization was being led and the impact on top priority work, adding that he was limited with how much more he could share due to the nature of this situation.
Twitter appointed Peiter Zatko, one of the world’s best-regarded hackers, as its head of security in 2020 with the aim to tackle everything from engineering mis-steps to misinformation.
Peiter Zatko used to oversee security at the electronic payments unicorn Stripe before which he worked on special projects at Google and used to handle out grants for projects on cyber-security at the Pentagon’s Defense Advanced Research and Projects Agency (DARPA).
Rinki Sethi also joined Twitter after the hack and, alongside Peiter Zatko, was charged with improving the company’s security and protecting its user data.
Parag Agrawal, who was appointed Twitter’s chief executive in November, has shuffled the company’s executives since taking over from Jack Dorsey, a founder.
Parag Agrawal earlier announced a significant reorganization of the top executives in the company, according to a filing with the US Securities and Exchange Commission.
Twitter earlier confirmed that Michael Montano, engineering lead and Dantley Davis a, design and research lead – have already stepped down from their roles on December 31.
