Peiter Zatko, the prominent computer security expert who blew the whistle last year on alleged security problems at Twitter Inc., is joining the cybersecurity firm Rapid7 Inc., the company said Wednesday.

Zatko, known more commonly by his hacker-era name “Mudge,” will advise Rapid7’s executive team and customers in a part-time role, a spokesperson said. He will report directly to Boston-based Rapid7’s chief executive officer, Corey Thomas, who called Zatko’s extensive experience “invaluable.”
