Twitter whistleblower to detail ‘dire’ security threats ahead of Musk deal vote

A former Twitter Inc executive turned whistleblower is set to testify on Tuesday before a U.S. Senate committee about his claims of serious security lapses at the social media network.

A deadline for Twitter shareholders to vote on Elon Musk’s deal to buy the company also falls on Tuesday.

The testimony of Peiter “Mudge” Zatko, a famed hacker who served as Twitter’s head of security until his firing last year, comes as Twitter and Musk head to trial next month over whether the $44 billion deal should be completed.
