Peiter Zatko, the former Twitter security chief who’s accused the company of negligence with privacy and security in a whistleblower complaint, will testify before Congress on Tuesday.
Zatko is well-respected in the cybersecurity space, which gives his complaints extra weight. But so far he has little documentary support for his claims — unlike the Facebook whistleblower, Frances Haugen, whose complaint last year included troves of internal documents from the company now called Meta.
