Twitter whistleblower Peiter “Mudge” Zatko portrayed the social-media giant as a cesspool of cybersecurity and privacy risks in dramatic congressional testimony on Tuesday — and even claimed the site had at least one undercover Chinese agent on its payroll.
Zatko, a famed hacker who worked as Twitter’s head of security between November 2020 and early this year, was called to testify after he filed a dramatic whistleblower complaint in August alleging that the site poses a risk to national security. Twitter has accused him of making misleading claims.
