Musk Seeks Details From Twitter Whistleblower

Elon Musk’s legal team sent a subpoena to Peiter Zatko, Twitter former head of security whose whistleblower complaint accusing the social-media company of “egregious deficiencies” related to privacy, digital and physical security, platform integrity and content moderation was made public last week.

Mr. Musk seeks documents and communications from Mr. Zatko about how the company measures and deals with fake and spam accounts, as well as information pertaining to reports about the company’s alleged security vulnerabilities that were sent to Chief Executive Parag Agrawal or other executives, according to legal filings made public Monday.
