On September 13 a Twitter leaker will meet before a Senate subcommittee

On September 13, the U.S. Senate Judiciary committee will hold a hearing with former Twitter Inc (NYSE:TWTR) security chief Peiter "Mudge" Zatko to investigate his whistleblower complaint alleging that the social media company duped regulators.

According to a spokeswoman for Zatko, he has previously raised his complaint with the staffs of the Senate Judiciary Committee chair and ranking member, the House Energy and Commerce Committee, and the Senate Intelligence Committee. Zatko accused Twitter of fraudulently asserting that it had a good security plan and making misleading comments regarding its defenses against hackers and spam accounts.

According to documents provided to congressional investigators, Zatko, a renowned hacker also known as "Mudge," alleged in an 84-page complaint that Twitter prioritized user growth over reducing spam, with executives eligible to win individual bonuses of up to $10 million tied to increases in daily users, but nothing explicitly for reducing spam.

Twitter has referred to the claim as a "fake story."

"The Senate Judiciary Committee will further investigate this matter with a full committee hearing during this work period, and will take any additional steps required to get to the bottom of these alarming allegations," said committee chair Senator Richard Durbin and leading Republican member Senator Chuck Grassley.

This week, Zatko also met with Senator Richard Blumenthal's staff members. Blumenthal is a Democrat who serves on the Senate Commerce Committee and the Judiciary Committee.

According to disclosures and evidence provided by Peiter 'Mudge' Zatko, a reputable cybersecurity expert who served as Twitter's Security Lead from 2020 to 2022, Twitter executives allegedly failed to address significant security vulnerabilities, neglected the mishandling of personal data, and disregarded known privacy risks to users for over a decade.

Blumenthal urged an investigation by the FTC in his letter.
