The former Twitter Inc. security chief alleging that the company misled investors about data protection issues is no stranger to high-pressure situations. 

Peiter Zatko, also known by the hacker nickname “Mudge,” is a longtime cybersecurity executive who over the years has held various technology-related roles with the US Defense Advanced Research Projects Agency, Google and the payment service Stripe Inc. It’s a resume that’s earned Zatko a distinguished cyber pedigree, and a career that began in earnest with congressional testimony about vulnerabilities in global technology.
