Twitter whistleblower bringing security warnings to Congress

WASHINGTON (AP) — Peiter “Mudge” Zatko, the Twitter whistleblower who is warning of security flaws, privacy threats and lax controls at the social platform, will take his case to Congress on Tuesday.

Senators who will hear Zatko’s testimony before the Senate Judiciary Committee are alarmed by his Twitter allegations at a time of heightened concern over the safety of powerful tech platforms.

It’s Zatko’s second Capitol Hill appearance, and in some ways a 21st-century echo of his first. In 1998, he testified before a Senate panel along with fellow members of a hacker collective who warned about the security dangers of the then-emerging internet age.

Zatko, a respected cybersecurity expert, was Twitter’s head of security until he was fired early this year. He has brought the stunning allegations to Congress and federal regulators, asserting that the influential social platform misled regulators about its cyber defenses and efforts to control millions of “spam” or fake accounts.
